2007-11-17    Josh Green <jgreen@users.sourceforge.net>

	* FluidSynth release 1.0.8 "Its about funky time!"
	* configure.ac: Bumped LT_REVISION and added call to AM_PROG_CC_C_O macro.
	* Makefile: Updated fluidsynth.prj to fluidsynth.anjuta
	* README-OSX: Update from Ebrahim Mayat for OS X Leopard
	* acinclude.m4: Fixed embedded main function in AM_PATH_READLINE macro.

2007-11-11    Josh Green <jgreen@users.sourceforge.net>

	* configure.ac: Added --enable-trap-on-fpe and --enable-fpe-check to
	  assist with Floating Point Exception debugging.
	* src/fluid_chorus.c: Reverted the rest of the chorus "Effect level clip"
	  patch, until something better is devised.
	* src/fluid_synth.c: Added support for trapping on Floating Point
	  Exceptions on GLIBC systems, to aid developers in tracking down FPEs
	  with gdb, removed buffer alignment hacks since they are no longer
	  needed (not using SSE currently).
	* src/fluid_sys.c (fluid_time_config): Added check for a CPU freq
	  calculation of 0.0, since this test is inadequate to begin with and
	  was coming up as 0.0 on my laptop, causing a FPE.  Will replace with
	  real timer functions, in the future.
	* src/fluid_voice.c: Removed zap_almost_zero macro as it was buggy and
	  had issues which went away when gcc optimization was turned off and in
	  the case of !WITH_FLOAT was using abs() which is integer based and
	  would cause FPEs.
	  (fluid_voice_write): Removed a memory alignment hack and moved a call
	  to fluid_fpe_check() to a better location.
	  (fluid_voice_effects): Replaced zap_almost_zero with a call to fabs(),
	  added fluid_fpe_check() call.
	* src/fluidsynth_priv.h: Removed FLUID_ALIGN16BYTE hack, as it is no
	  longer needed.

2007-11-10    Josh Green <jgreen@users.sourceforge.net>

	* doc/fluidsynth.1: Updated man page with current command line options and other changes (minor).
	* include/fluidsynth/synth.h: Reverted "Effect level clip" patch as it seems to cause chorus
	  count to have a much lessor effect.

2007-09-20    Josh Green <jgreen@users.sourceforge.net>

	* Doc updates to AUTHORS and latest README-OSX from Ebrahim Mayat.
	* src/config_win32.h.in: VERSION is now filled in at configure time.
	* src/fluid_alsa.c (fluid_alsa_audio_run_s16): Fixed bug which was
	  causing weird crashes with QSynth when new_fluid_audio_driver2() when
	  audio meters were enabled (user data parameter was being used as a
	  fluid_synth_t instance).  Synth instance is now no longer used in
	  this case (it was only used for 16 bit dithering before).
	* src/fluid_oss.c: Fixed the same bug that was affecting ALSA driver.
	* src/fluid_rev.c: Reverted to old commented out code in regards to
	  reverb level.
	* src/fluid_synth.c (fluid_synth_dither_s16): Now no longer uses
	  fluid_synth_t instance, but accepts a pointer to an integer instead
	  for keeping track of dithering buffer index (all that the synth instance
	  was being used for).
	* src/fluid_synth.c (fluid_synth_one_block): Reverted patch which
	  performs assignment of chorus and reverb levels in synthesis loop,
	  until a better scheme is devised (unnecessary CPU consumption).
	* Added Visual Studio .sln and .vcproj files and some minor source
	  changes to get FluidSynth to build with it.
	* Back-converted Visual Studio project to VC++ 6 project for users
	  using that build platform (not tested).

2007-09-02    Josh Green <jgreen@users.sourceforge.net>

	* configure.ac: Removed SSE and longlong related switches (SSE support
	  removed for now and longlong is now always used).
	* : Applied effect level clip patch from David Hilvert
	  see http://fluidsynth.resonance.org/trac/ticket/2.
	* : Applied reverb damp scaling patch from David Hilvert
	  see http://fluidsynth.resonance.org/trac/ticket/3.
	* src/fluid_dsp_float.c: No longer being #include'd and all interpolation
	  functionality has been re-written as separate functions, interpolating
	  around loops is now supported, effect (reverb/chorus/pan/filter) stuff
	  moved to fluid_voice.c.
	* src/fluid_phase.h: 64 bit unsigned integers are now used for phase
	  index/fraction sample pointers, modified macros accordingly.
	* src/fluid_voice.c: Removed SSE code, fluid_voice_init() renamed to
	  fluid_dsp_float_init() and moved to fluid_dsp_float.c.  Effect related
	  functionality (reverb/chorus/pan/filter) moved from fluid_dsp_float.c
	  to fluid_voice.c.  Some code re-formatting and comment cleanup.  Loop
	  no longer requires padding surrounding it (fixes bug related to loop
	  point right on the end of the sample).

2007-08-18    Josh Green <jgreen@users.sourceforge.net>

	* src/fluid_alsa.c: Added SND_SEQ_PORT_TYPE_MIDI_GENERIC back into the
	  ALSA sequencer port registration as it broke the use of playmidi
	  (thanks to Dave Serls for providing a patch and pointing this out).

2007-01-14    Josh Green <jgreen@users.sourceforge.net>

	* src/fluid_alsa.c: Fixed evil bugs in ALSA driver where return value
	  of new fluid_alsa_handle_write_error() was not being checked correctly
	  causing successfully handled ALSA errors (underruns for example) to
	  terminate audio thread.
	* src/fluid_synth.c: Using an inline roundi function to replace roundf
	  as per suggestion by Mihail Zenkov, 16 bit for dithering.

2006-12-10    Josh Green <jgreen@users.sourceforge.net>

	Lots of documentation updates.
	* doc/Doxyfile: No longer including functions by default, only those
	  listed in the listed header files.
	* src/fluid_strtok.[ch]: Removed, since it was crap.  Replaced with
	  fluid_strtok() in fluid_sys.c which doesn't require an allocated
	  tokenizing instance.
	* src/fluid_alsa.c: Audio processing is more optimized in the case where
	  no user defined audio callback is used (removal of unneeded buffer copy),
	  fluid_alsa_handle_write_error() added for centralized ALSA audio error
	  handling,
	* src/fluid_aufile.c: Now also doing 16 bit dithering.
	* src/fluid_cmd.c: Removed use of old tokenizer instance.
	* src/fluid_coreaudio.c: User defined callback function is now honored.
	* src/fluid_defsfont.c: More leaks plugged (thanks to Paul Millar for
	  the patch), removed sfont_free_data() since sfont_close() should be
	  used instead (don't want to leak a file handle).
	* src/fluid_midi_router.c: Took out uses of fflush() since sending a
	  line of text (with newline) should display it.
	* src/fluid_oss.c: Using fluid_synth_dither_s16() in place of old
	  16 bit conversion code.
	* src/fluid_settings.c: Replaced strtok stuff with new function, some
	  other improvements.
	* src/fluid_synth.c (delete_fluid_synth): Turning off all voices so that
	  SoundFont data will be freed correctly (thanks to patch from
	  Paul Millar).
	* src/fluid_sys.c (fluid_strtok): New function to replace old tokenizing
	  functions which required a token instance.
	* src/fluidsynth.c: Warning message printed if a non option is not a
	  valid SoundFont or MIDI file (thanks to Nick Daly for the patch).

2006-11-22    Josh Green <jgreen@users.sourceforge.net>

	* src/fluid_alsa.c (new_fluid_alsa_audio_driver2): Removed some ALSA
	  lib calls to set software parameters, which was likely causing the
	  100% CPU usage problem (not actually fixed in last update, not sure
	  which one is the culprit).
	  (fluid_alsa_seq_run): More changes in ALSA sequencer code, hopefully
	  it is right this time!
	  (delete_fluid_alsa_seq_driver): Memory leak fixed - wasn't freeing
	  array of sequencer file descriptors.
	* src/fluid_chan.c: Memory leak fixes: Now deleting preset from channel
	  when channel is destroyed.
	* src/fluid_cmd.c: Memory leak fix: strtok being deleted from command
	  shell when shell is destroyed.
	* src/fluid_defsfont.c: Memory leak fixes: Freeing modulator lists in
	  preset and instrument zones, freeing zone names, freeing instruments
	  linked from preset zones, replaced use of "safe_malloc" with FLUID_MALLOC
	  macro, deleting instrument list in SFData, deleting samples in SFData,
	  freeing SFData structure.
	* src/fluid_settings.c: Memory leak fix: freeing options in option
	  type settings.
	* src/fluid_synth.c: Memory leak fixes: Freeing FX buffers and
	  right/left_buf.

2006-11-21    Josh Green <jgreen@users.sourceforge.net>

	* src/fluid_alsa.c (new_fluid_alsa_audio_driver2): Modified all ALSA
	  calls to check return code error as "< 0" as per ALSA examples, sample
	  rate is now compared with what was expected and warning message displays
	  both values, if target sample rate wasn't set update the local
	  period_size variable (was causing 100% CPU consumption by ALSA, from
	  the resultant erroneous sw_params calls).
	  (fluid_alsa_audio_run_float): Using case statement for
	  error codes from snd_pcm_writen() for the sake of tidiness.
	  (fluid_alsa_audio_run_s16): Using case statement for error codes
	  from snd_pcm_writei() for the sake of tidiness, re-instated call
	  of device callback function that was broken with the dither patch
	  (don't want to break the API), now using new fluid_synth_dither_s16()
	  to convert floating point sample data to 16 bit with dithering.
	  (fluid_alsa_seq_run): Timeout in poll() call set to 100ms (from 1ms!),
	  snd_seq_event_input_pending is used to check if events are available
	  before calling snd_seq_event_input to prevent blocking, check of
	  snd_seq_event_input error code moved to the right location (bug fix).
	* src/fluid_synth.h: Added dither_index parameter to fluid_synth_t
	  structure to allow for per synth dithering continuity.
	* src/fluid_synth.c: Modified dithering to use new dither_index field
	  for per synth dithering continuity, fixed off by 1 error with
	  dithering index comparison, removed usage of roundf in dithering (is
	  it sufficient to just integer truncate?).
	  (fluid_synth_dither_s16): New function to perform dithering on
	  buffers of floating point sample data.

2006-11-20    Josh Green <jgreen@users.sourceforge.net>

	* src/fluid_alsa.c: Applied dithering patch from Mihail Zenkov.
	* src/fluid_synth.c: Applied dithering patch from Mihail Zenkov.

2006-03-04    Josh Green <jgreen@users.sourceforge.net>

	* src/fluid_alsa.c (delete_fluid_alsa_audio_driver): Now calling
	snd_pcm_close() to close the ALSA audio driver handle.
	(fluid_alsa_seq_run): Check for -ENOSPC error was logicly inverted.
	(new_fluid_alsa_seq_driver): Sequencer is now opened in blocking mode.

2006-02-20    Josh Green <jgreen@users.sourceforge.net>

	* Fixed build error that occured when neither LASH or LADCCA are
	  present.
	* Updated README-OSX from Ebrahim Mayat.

2006-02-18    Josh Green <jgreen@users.sourceforge.net>
	* FluidSynth release 1.0.7 "Increasing Fluidity.."

	* Removed spurious newlines from FLUID_LOG statements throughout.
	* AUTHORS: Some cleanup and additions.
	* src/fluid_lash.[ch]: Moved LADCCA related code from fluidsynth.c here
	  and added new LASH support (both old LADCCA and LASH are supported
	  exclusively). Used patches sent by Frieder B├╝rzele as a guide.
	* src/fluidsynth.c: Removed LADCCA code (now in fluid_lash.c),
	  re-organized command line parsing and removed duplicate WIN32 switch
	  statement, re-organized help output and added missing entries, added
	  "-o help" switch for listing settings, welcome message now printed
	  whenever FluidSynth is run and simplified,
	  (print_usage): hard coded application name as "fluidsynth".
	* configure.ac: Changed --enable-SSE option to --enable-broken-SSE
	  and --enable-SSE now just displays a fat warning about not using it.
	* src/fluid_jack.c: Warning is now displayed if synth sample rate
	  doesn't match jackd.
	* src/fluid_alsa.c: Added detection for ALSA sequencer buffer overrun
	  (-ENOSPC) and interrupted poll() call (-1??).
	* src/fluid_voice.c: Applied patch from Henri Manson which adds a
	  fluid_ct2hz_real() function which does not have the filter cutoff
	  limits that fluid_ct2hz() does, new function being used for
	  calculations that may include non-audible frequencies.
	* src/fluid_dsound.c: Applied patch from Henri Manson which
	  only creates the directsound window once.

2005-09-04    Josh Green <jgreen@users.sourceforge.net>

	* src/fluid_ramsfont.c (fluid_ramsfont_remove_izone): Applied crash bug
	fix from Antoine Schmitt.

2005-07-05    Josh Green <jgreen@users.sourceforge.net>

	* src/fluidsynth_priv.h: FLUID_ALIGN16BYTE is broken on AMD64 so now
	only enabled if SSE is being used. If SSE code becomes more useful in
	the future this should be fixed.

2005-06-29    Josh Green <jgreen@users.sourceforge.net>

	* Applied LASH patch that is included with ladcca-0.4.0.

2005-06-11    <jgreen@users.sourceforge.net>

	* Released FluidSynth 1.0.6 "Music to my ears"

	* README-OSX: Update from Ebrahim Mayat.
	* acinclude.m4: Midishare support now defaults to auto.
	* configure.ac: Added LT_CURRENT, LT_REVISION and LT_AGE in place of
	  LIBFLUIDSYNTH_MAJ and LIBFLUIDSYNTH_MIN to make better use of
	  libtool library versioning.  Fixed use of AC_ARG_ENABLE (was setting
	  variables to yes even when disable was specified), fixes --disable-SSE
	  which was reported by Mikhail Yakshin, added warning when SSE is
	  enabled to let users know that this feature isn't really desirable
	  currently.
	* src/Makefile.am: Now using LT_VERSION_INFO to substitute the libtool
	  version.
	* src/fluid_cmd.c (fluid_cmd_handler_handle): Modified to avoid GCC
	  "type-punned" cast warning.
	* src/fluid_defsfont.c (fluid_preset_zone_import_sfont): Fixed
	  assignment of modulator amtsrc flags (should be assigned to flags2
	  not flags1), thanks to Stephan Tassart for reporting this.
	  (fluid_inst_zone_import_sfont): Same fixes as for above.
	* src/fluid_sys.c (fluid_log): Now using vsnprintf for formatting
	  error messages to fix buffer overflow as reported by Axioplase.
	  (fluid_debug): Same as above.

2005-06-11    <jgreen@users.sourceforge.net>

	* fluidsynth.prj: Added Anjuta project file.
	* src/fluid_conv.c: fluid_cb2amp conversion set back to real centibels
	  and added a new fluid_atten2amp table conversion for non-standard
	  EMU 8k/10k attenuation.
	* src/fluid_voice.c (fluid_voice_write): Updated volume calculations to
	  use fluid_cb2amp for envelope and LFO, but use fluid_atten2amp for
	  initial attenuation.
	  (fluid_voice_noteoff): Re-coded volenv_val attack conversion and
	  verified.

2005-06-10    <jgreen@users.sourceforge.net>

	* src/fluid_phase.h: Patch from Sean Bolton to fix big endian long long
	  phase combined 64 bit value type fluid_phase_t
        * src/fluid_voice.c (fluid_voice_update_param): case GEN_OVERRIDEROOTKEY
	  was incorrectly adding pitchadj fine tune amount instead of subtracting
	  it.  Also, fine tuning should be applied to root key override as well.

2005-06-07    <jgreen@users.sourceforge.net>

        * Applied Sean Bolton's DSSI patch (SB patch) which adds the ability to
	  change polyphony at runtime and fixes a bug (see below).
	* README-OSX: Update from Ebrahim Mayat for OSX Panther.
	* include/fluidsynth/synth.h: Sean Bolton's DSSI patch adds two new
	  functions fluid_synth_set_polyphony and fluid_synth_get_polyphony.
	* src/fluid_conv.c: Centibel to amplitude conversion now follows
	  EMU 8k/10k which is contrary to SoundFont specification (TiMidity++
	  used as an example).
	* src/fluid_conv.h: FLUID_CB_POWER_FACTOR defined for the centibel->amp
	  conversion table equation.
	* src/fluid_defsfont.c (load_pgen): Fixed 'use of cast expressions as
	  lvalues is deprecated' warning by casting the value being assigned
	  instead of the variable assigned to and removed code warrior
	  specific code to work around this.
	  (load_igen): Same as for load_pgen.
	* src/fluid_synth.c: SB patch - uses synth->polyphony instead of
	  synth->nvoice when iterating over the synth's voices.
	  (fluid_synth_update_polyphony): SB patch (new) - runtime update
	  (fluid_synth_set_polyphony): SB patch (new)
	  (fluid_synth_get_polyphony): SB patch (new)
	  (fluid_synth_nwrite_float): SB patch - fixes bug where the use of
	  arbitrary values of the 'len' parameter was broken.
	* src/fluid_voice.c (fluid_voice_write): modlfo_to_vol (modulation LFO
	  to volume) was being calculated inverted (should be negative
	  attenuation, gain, for a positive rise in LFO).
	  (fluid_voice_noteoff): Updated centibel to amplitude conversion
	  used when voice off during attack to use the new
	  FLUID_CB_POWER_FACTOR.

2004-11-11    <jgreen@users.sourceforge.net>

	* README-OSX: Update from Ebrahim Mayat.

2004-08-18    <peter@hanappe.com>

	* src/fluid_synth.c (fluid_synth_set_bank_offset): 
	(fluid_synth_get_bank_offset): New API to set
	a bank offset in a SoundFont (proposition made by Ken Ellinwood).

2004-08-06    <peter@hanappe.com>

	* src/fluid_synth.c (fluid_synth_noteon):
	fluid_synth_release_voice_on_same_note() is now called in the
	noteon() function instead of in fluid_synth_start(). This fixes
	the silent note problem!

2004-07-29    <peter@hanappe.com>

	* src/fluid_chan.c (fluid_channel_cc): Applied Ken Ellinwood's
	fix for the bank select (MSB) message.
 
	* src/fluid_jack.c (fluid_jack_audio_driver_settings): Applied Rui
	Nuno Capela's patch

2004-05-14    <peter@hanappe.com>

	* doc/fluidsynth.1 (option): Fixed typo noted by Gerald Pye.

2004-05-14    Peter Hanappe <peter@hanappe.com>

	* src/fluid_dsound.c (fluid_dsound_enum_callback): Applied Sergey
	Pavlishin's patch. This path fix stack overflow during DirectSound
	audio driver initialization.

2004-05-07    Peter Hanappe <peter@hanappe.com>

	* src/fluid_synth.c (fluid_synth_remove_sfont): Added new function

2004-05-05    Peter Hanappe <peter@hanappe.com>

	* src/fluid_alsa.c (new_fluid_alsa_seq_driver): The alsa driver
	now opens several ports if the synthesizer is configured for more
	than 16 MIDI channels.

	* src/fluid_voice.c (fluid_voice_write): I removed the filter
	on/off optimization. The filter is always on and serves as an
	anti-aliasing filter.

2004-05-04    Peter Hanappe <peter@hanappe.com>

	* src/fluid_synth.c (new_fluid_synth): The number of MIDI channels
	now has to be a multiple of 16. The synth checks that this is the
	case and changes the settings accordingly. I removed the sanity
	checks for the min/max value of the number of MIDI channels since
	this is already done by the settings object.

2004-03-30    Josh Green <jgreen@users.sourceforge.net>

	* src/fluid_voice.c (fluid_voice_write): Altered filter turn-off
	optimization to not turn filter off once it has been
	enabled. There is still a potential for a click when it gets
	turned on though, which needs to be dealt with.

2004-03-30    Peter Hanappe <peter@hanappe.com>

	* src/fluid_dsp_core.c: I've split up the dsp core file in three
	files: fluid_dsp_simple.c, fluid_dsp_float.c, and
	fluid_dsp_sse.c. This improves the readability.

2004-03-29    Peter Hanappe <peter@hanappe.com>

	* src/fluid_jack.c (new_fluid_jack_audio_driver2): Testing the
	number of ports before allocating them.
	(fluid_jack_audio_driver_settings): Registering
	the "audio.jack.autoconnect" setting.

	* src/fluid_midi.c (fluid_player_set_midi_tempo): Tempo changes
	handled correctly. Was broken after fix on [2004-03-22] (see
	below).

	* src/fluid_strtok.c (fluid_strtok_char_index): Removed printf's
	from fluid_strtok.c

2004-03-26    Peter Hanappe <peter@hanappe.com>

	* bindings/README: Imported the fluidsynth_jni and fluidmax
	projects.
	
2004-03-25    Peter Hanappe <peter@hanappe.com>

	* src/fluid_rev.c (new_fluid_revmodel): Added 'gain', similar as
	in Freeverb 3. Using same 'wetscale' as Freeverb 3, but fixing
	'wet' to 3. fluid_revmodel_setlevel() does not change the value of
	'wet': The 'wet' level can be controlled with the 'reverb send'.
	(fluid_revmodel_processreplace): The input is multiplied by 2 and
	by the gain. This corresponds to the channel mixing and scaling
	that Freeverb 3 does.

2004-03-24    Peter Hanappe <peter@hanappe.com>

	* src/fluidsynth.c (main): Added the -f switch. Passing "-f file"
	on the command line tells fluidsynth to read parse the file and
	execute and commands.  
	(main): User config and system config file are now loaded correctly

	* src/fluid_cmd.c (fluid_shell_run): the shell doesn't get stuck
	and loop on an emtpy string when the end of the stream is reached.

	* src/fluid_io.c (fluid_istream_gets): fluid_istream_gets()
	returns 0 if the end of the stream was reached and -1 on error.

	* src/fluid_cmd.c (fluid_source): Fixed bug in "file =
	open(filename, FLAGS);" (I shouldn't pass O_WRONLY when what I
	want is O_RDONLY!)

2004-03-23    Peter Hanappe <peter@hanappe.com>

	* src/fluid_aufile.c (new_fluid_file_audio_driver): Added
	fluid_aufile.c. This file implements a audio driver that writes
	the audio output to a file. This driver is NOT real-time and is
	currently useful for testing purposes only (not even useful to
	play MIDI files).

2004-03-22  Peter Hanappe <peter@hanappe.com>

	* src/fluid_synth.c (new_fluid_synth): Removed the synth->busy
	mutex. I don't think it is necessary; to be discussed.

	* src/fluid_midi.c (fluid_player_callback): Fixed the timing in
	the MIDI playback. The current MIDI tick in every timer callback
	was calculated as an increment to the previous number of
	ticks. This introduces a growing error due to rounding errors and
	timer variations. The current tick is now calculated according to
	the absolute time at the beginning of the file. (Beginners error
	...)

	* doc/FluidSynth-LADSPA.pdf: Added Markus' LADSPA design document.

	* doc/xtrafluid.txt: Added Antoine's Xtra API documentation.

	* doc/midi_time.txt: Added a memo on midi timing.

2004-03-19  Peter Hanappe <peter@hanappe.com>

	* src/fluid_midishare.c: Applied Stephane Letz patch: MidiShare is
	now connected to fluidsynth by default so that received MIDI
	events directly trigger the synth
	
2004-02-28  Peter Hanappe <peter@hanappe.com>

	* src/fluid_synth.c: Added fluid_synth_program_select2() and
	fluid_synth_get_sfont_by_name() in fluid_synth.c. These functions
	are not in the public API, yet.

2004-02-25  Peter Hanappe <peter@hanappe.com>

	* src/fluid_voice.c: Fixed bug in volume envelope (in
	fluid_voice_update_param(), case GEN_VOLENVDECAY): the minimum
	value was converted to linear amplitude instead of a normalized
	value of the cB (1-cB/1000). Because of that, the decay section
	went on for too long.

2004-12-xx  Peter Hanappe <peter@hanappe.com>

	* src/fluid_seq.c: Inserting events in the queueLater list was
	incomplete. It didn't check if the event was the last in the list,
	and the looping through the list didn't update the prev pointer. I
	added muteces to the sequencer. Events are dynamically allocated
	if no free events are available. The sequencer is protected by a
	mutex.
 
2003-11-14  Josh Green  <jgreen@users.sourceforge.net>
	* src/fluidsynth.c: Removed CCA_Use_Jack and CCA_Use_Alsa flags
	since LADCCA no longer uses them.

2003-08-31  Josh Green  <jgreen@users.sourceforge.net>

	* acinclude.m4: Renamed AC_SOUND macro to AC_OSS_AUDIO and removed
	the ALSA check from it since pkg-config is now being used to check
	for ALSA. Also fixed --enable-alsa-support and --enable-oss-support
	which were disabling support instead (reported by Bart Massey).
	* configure.ac: pkg-config is now being used to check for ALSA.
	ALSA and OSS now use automake conditionals to conditionally compile
	source files.
	* Makefile.am: Re-arranged SUBDIRS so build output looks nicer.
	* src/Makefile.am: ALSA and OSS are now conditionally compiled using
	automake conditionals.

2003-08-29  Josh Green  <jgreen@users.sourceforge.net>

	* src/fluid_sys.c: Patch from Eric Van Buggenhaut to make i386 asm
	code not compile for all non-i386 archs rather than just DARWIN.
	* src/fluidsynth_priv.h: Patch from Sergey Pavlishin to fix
	FLUID_REALLOC macro.
	* src/fluid_cmd.c: Ken Ellinwood's patch to add -verbose to "channels"
	command, and print settings values with 3 decimal places.
	* src/fluid_defsfont.c (fluid_defsfont_sfont_get_preset): Ken
	Ellinwood's patch to initialize sfont field of preset.
	* src/fluid_ramsfont.c (fluid_ramsfont_sfont_get_preset): Ken
	Ellinwood's patch to initialize sfont field of preset.
	* src/fluid_midi.c (fluid_midi_file_read_event): Fixed a crash bug with
	zero length MIDI meta events that was pointed out by Sergey Pavlishin.
	(delete_fluid_midi_event): Fixed a stack overflow problem pointed out
	by Sergey Pavlishin that was caused by recursively deleting MIDI
	event linked list, now just using a while loop.

2003-08-25  Josh Green  <jgreen@users.sourceforge.net>

	* src/fluidsynth.c: MIDI channels switch should be -K not -L as was
	listed in "Usage" output, also -K was setting audio.channels for
	non getopt case statement - changed to midi.channels. Added a new
	option "-l, --disable-ladcca" to disable LADCCA server connection.

2003-08-25  Josh Green  <jgreen@users.sourceforge.net>

	Release version 1.0.3

	* doc/fluidsynth.1: Applied typo patch from Eric Van Buggenhaut.
	* TODO: Restructuring TODO file (removing old stuff).
	* doc/Doxyfile: Disabled Tex doxygen generation and changed
	OUTPUT_DIRECTORY to api/.
	* doc/Makefile.am: Added an update-docs target and related for updating
	developer doc and doxygen reference HTML. Also added update-docs to
	dist-hook for updating before distribution packaging.
	* include/fluidsynth/synth.h: Some fixes to doxygen documentation.
	* fluidsynth.spec.in: New RPM spec file which is generated at configure
	time.
	* Makefile.am: Added fluidsynth.spec(.in) to EXTRA_DIST.

2003-08-19  Josh Green  <jgreen@users.sourceforge.net>

	* src/fluid_alsa.c: Added some calls to snd_strerror() to print out
	details of ALSA routine failures.
	* src/fluid_defsfont.c: Put a message about SoundFont loading code
	being borrowed from Smurf SoundFont Editor.
	* src/fluid_rev.c: Valgrind found that some values were being used
	uninitialized because fluid_revmodel_update() was being called before
	all reverb parameters were set, now setting manually and then calling
	update routine.
	* src/fluid_voice.c: Increased FLUID_MAX_AUDIBLE_FILTER_FC to minimize
	clicks from filter toggling. Added a FLUID_MIN_VOLENVRELEASE constant
	to set the minimum volume envelope release to minimize clicks.

2003-07-22  Josh Green  <jgreen@users.sourceforge.net>

	* src/fluid_midishare.c: Added include of header "config.h" as
	per Albert Graef's request.
	* src/fluid_voice.c (fluid_voice_optimize_sample): Moved a
	variable declaration to the beginning of function, it was
	causing problems with at least one user.

2003-06-28  Josh Green  <jgreen@users.sourceforge.net>

	* src/fluid_defsfont.c: Moved call to fluid_voice_optimize_sample
	from fluid_inst_zone_import_sfont to fluid_defsfont_load. Also
	reduced minimum sample size before rejection from 48 to 8 (could
	be lower?).
	* src/fluid_voice.c (fluid_voice_optimize_sample): Added a check
	for sample->valid to ignore ROM samples which was causing a crash
	with Vintage Dreams and other SoundFont files with ROM samples.

2003-06-17  Josh Green  <jgreen@users.sourceforge.net>

	Release version 1.0.2
	Added Makefile.am files where lacking.

	* Makefile.am: Fixes to "make dist" target by adding macbuild, sf2
	and winbuild to SUBDIRS also removed acconfig.h from EXTRA_DIST.
	* acinclude.m4: Removed AC_JACK, now using pkgconfig.
	* configure.ac: Updated to version 1.0.2, Jack test now using
	pkgconfig and built by default if found, coreaudio driver now built
	by default if found.
	* doc/Makefile.am: Added Doxyfile, example.c, example.sf2, fluidsynth.1
	and fluidsynth-v10-devdoc.xml to EXTRA_DIST.
	* src/Makefile.am: fluid_jack.c now conditionally built, fluid_sse.h
	added to EXTRA_DIST.
	* src/fluid_jack.c: #if JACK_SUPPORT removed as its not needed.

2003-06-15  Josh Green  <jgreen@users.sourceforge.net>

	* configure.ac: Fixed detection of CoreAudio by looking for
	CoreAudio/AudioHardware.h.
	* src/Makefile.am: Added COREAUDIO_CFLAGS and COREAUDIO_LIBS.
	* src/fluid_coreaudio.c: Added CoreAudio prefix to #include headers
	(fluid_core_audio_callback): Fixed declarition to match that of the
	typedef in CoreAudio header to stop warnings.
	* fluidsynth.c: Now including fluidsynth_priv.h to include the arch
	specific definitions in there (perhaps should be done in configure
	script though).
	* fluidsynth_priv.h: Added "#define WITHOUT_SERVER 1" to Darwin build.

2003-06-12  Josh Green  <jgreen@users.sourceforge.net>

	* Makefile.am: Added autogen.sh to EXTRA_DIST
	* acinclude.m4: Added AM_PATH_READLINE macro for readline detection
	and prefix configuration.
	* configure.ac: Support for MinGW32 build, Darwin build fixes,
	configure CFLAGS input value now honored, fixes to CoreAudio support,
	and better readline detection and config.
	* src/Makefile.am: Now conditionally compiling CoreAudio and Windows
	sources, added config_*.h files to EXTRA_DIST, some stuff for MinGW32
	build, READLINE_LIBS and READLINE_CFLAGS now used.
	* src/fluid_dsound.c: Fixed some warnings by adding "void" for
	empty parameter procedure declarations.
	* src/fluidsynth.c: Don't include config_win32.h if MinGW32.
	* src/fluidsynth_priv.h: Stuff for MinGW32 and Darwin builds.
	* doc/fluidsynth-v10-devdoc.xml: Applied a diff from
	Alexandre Prokoudine.

2003-06-09  Josh Green  <jgreen@users.sourceforge.net>

	* src/fluid_alsa.c: Added calls to pthread_attr_setschedparam to
	properly create SCHED_FIFO threads.
	* src/fluid_oss.c: pthread_attr_setschedparam calls added.
	* src/fluid_midishare.c: Patch update from Stephane Letz.

2003-05-29  root  <mn@bongo>

	* src/fluid_synth.c (fluid_synth_one_block): Added a mutex that
	provides a small degree of protection against noteons / noteoffs,
	when the audio thread is working.

	* src/fluid_synth.h (struct _fluid_synth_t): 

	* src/fluid_voice.c (fluid_voice_optimize_sample): 

2003-05-29  Markus Nentwig  <nentwig@users.sourceforge.net>

	* include/fluidsynth/voice.h: added fluid_voice_gen_incr to api
	* src/fluidsynth.c: Added error message for command line parameter handling
	* src/fluid_voice.c (fluid_voice_optimize_sample): Removed loop peak detection 
	at run time, because it caused dropouts. Now the sound font loader or application 
	is responsible to call fluid_voice_optimize_sample (if it doesn't, the turnoff optimization is 
	simply disabled).
	
1999-11-30  Antoine Schmitt  <as@gratin.org>

	* src/fluid_defsfont.c: inst_zone lokey is now properly inialized to 0
	(it was not, leading to random lost noteons depending on memory
	initialization)

2003-04-03  Peter Hanappe  <peter@hanappe.com>

	* src/fluid_rev.c: reverb parameters are clipped to their valid
	range.

	* src/fluid_alsa.c: using fluid_alsa_audio_run_s16 as default
	function. This reduces the high CPU usage.

	* src/fluid_voice.c (fluid_voice_write): filter interpolation done
	over only 1 buffer to avoid filter instability

	* src/fluid_chan.c (fluid_channel_init): bank number set to 128
	for the drum channel

	* src/fluid_midi.c (fluid_midi_file_read_event): Correctly reading
	pitchbend value

2003-02-27  Josh Green  <jgreen@users.sourceforge.net>

	Updated automake files (automake 1.6).

	* configure.ac: New version autoconf variables which get substituted
	into include/iiwusynth/version.h.in.
	* include/iiwusynth/version.h.in: Version defines that are filled in
	by autoconf.
	* src/Makefile.am: Fixed SOURCES including removing headers that are
	now in include/iiwusynth/, added missing sources (iiwu_ramsfont.[ch],
	iiwu_sfont.h) and added iiwu_dsp_core.c to EXTRA_DIST.
	* doc/Makefile.am: Added iiwusynth.1 to EXTRA_DIST.
	* include/iiwusynth.h: Added version.h.
	* iiwusynth/Makefile.am: Added version.h to the installed headers.

2003-02-08  Markus Nentwig <nentwig@users.sourceforge.net>

	* src/iiwu_ladspa.c: Added a very small signal at Nyquist
	frequency. This fixes denormal number problems in some
	plugins.
	* src/iiwu_cmd.c (iiwu_shell_run): Now also invalid input lines
	are added to the command line history. So the user can just scroll
	up and fix them.
	* src/iiwu_ladspa.c: Cleaned up error messages
	* src/iiwu_dsp_core.c: Disabled SSE interpolation, because it is
	slower than the normal code
	* autogen.sh: Added a line, that checks for the presence of pkg-config in
	autogen.sh.
	Motivation: It took me some time to figure out what was wrong...
	It produces some error message instead of an obscure error later
	during ./configure, if pkg-config is not installed.
		
2003-02-07  Josh Green <jgreen@users.sourceforge.net>

	Applied another Bob Ham LADCCA patch.

	* src/iiwu_alsa.c: LADCCA patch: Now using a ladcca.enable setting.
	* src/iiwu_jack.c: LADCCA patch: ladcca.enable setting and jack ports
	are no longer auto connected unless audio.jack.autoconnect is set.
	* src/iiwusynth.c: LADCCA patch: ladcca.enable and command line options
	-j and --connect-jack-outputs to enable Jack autoconnect.

2003-02-05  Josh Green <jgreen@users.sourceforge.net>

	Applied Bob Ham's LADCCA and pkgconfig patches.

	* Makefile.am: pkgconfig patch.
	* configure.ac: Renamed from configure.in as per new autoconf
	standards. LADCCA configure switch and detection. FluidSynth.pc
	pkgconfig file output.
	* src/Makefile.am: LADCCA patch.
	* src/iiwu_alsa.c [HAVE_LADCCA]: LADCCA patch: reports ALSA
	sequencer client ID.
	* src/iiwu_jack.c [HAVE_LADCCA]: LADCCA patch: reports JACK
	client name.
	* src/iiwusynth.c [HAVE_LADCCA]: LADCCA patch: connects to LADCCA
	server, creates client thread, saves/restores SoundFont file state.
	Used iiwu_sfont_get_name macro to get SoundFont file names contrary
	to the patch. Should these macros be public? Included unistd.h
	for usleep call (within HAVE_LADCCA).

2003-01-23  Josh Green <jgreen@users.sourceforge.net>

	* src/iiwu_jack.c: Fixed a segfault bug caused by freeing jack
	port names, when really only the port array should be freed,
	jack reference docs are confusing on this matter!
	* src/iiwu_voice.c (iiwu_voice_check_sample_sanity): Min loop size
	and padding now set via constants IIWU_MIN_LOOP_SIZE and
	IIWU_MIN_LOOP_PAD defined at top of iiwu_voice.c, and the values
	were lowered to exceed SF spec requirements rather then just meet.
	(iiwu_voice_write): Now using a constant IIWU_MAX_AUDIBLE_FILTER_FC
	defined at the top of iiwu_voice.c to control the filter
	cutoff optimization. Also added IIWU_MIN_AUDIBLE_FILTER_Q so
	filter will only turn off if both cutoff and q are determined to be
	inaudible. Filter optimization is much less noticeable when modulating.

2003-01-14  Markus Nentwig <nentwig@users.sourceforge.net>

	* src/iiwu_ladspa.c: Adapted new command handler
	* src/iiwu_midi_router.c (midi_dump_prerouter): Added forgotten

	multi_channel from the settings (replaced with audio_channels > 1)
	* src/iiwu_settings.c (iiwu_settings_init): added audio_groups
	setting. This is the number of individual channels generated from
	the synth, and always equal to audio_channels, as long as the
	LADSPA Fx unit is disabled. Otherwise it can be used (for
	example) to separate even and odd MIDI channels, apply different Fx
	and mix together to one stereo output.

	and multiple audio output channels
	
2002-12-04  Peter Hanappe  <peter@hanappe.com>

	* src/iiwu_midi.c (iiwu_midi_file_read_event): the metadata buffer

	message as an well-behaved, interactive application should.

	* src/iiwu_synth.c (iiwu_synth_all_sounds_off): New function to
	implement the 'All Sound Off' MIDI messages (CC 120).
	(iiwu_synth_system_reset): This function now also resets the
	default controller values on the MIDI channels, and clears the
	reverb and chorus delay lines.
	(iiwu_synth_count_midi_channels): New function to retreive the
	number of available midi channels.
	(iiwu_synth_count_audio_channels): New function to retreive the

	line command 'rev_setwet' to 'rev_setlevel'. Replaced the word 'wet' by
	'level' in most places.
	 Added a command line option --dump, which provides
	 'machine-readable' output from stdout to hook up a user interface.
	* src/iiwusynth.h: Moved the default values for gain, chorus and
	reverb here. Might be useful as an example...
	* src/iiwu_voice.c (iiwu_voice_calculate_runtime_synthesis_parameters): 
	Added 'scale tuning' modulator, centered around C3.

	Amplitude scaling short => floating point is now done as the last
	operation in the DSP loop (voice->amp does not include the scaling
	factor anymore).	
	* src/iiwu_synth.c (iiwu_synth_one_block): Saved a couple of
	multiplications per sample by moving the master gain into iiwu_voice_write
	* src/iiwu_synth.c (iiwu_synth_free_voice_by_kill): Modified the algorithm

	* src/iiwu_voice.c: Added caching for loop peak detection: The
	amplitude of the loop is only detected once for each
	sample. Exception only, if the resulting loop differs from the
	original loop settings of the sample (in this case, the peak
	detection is still run for each noteon event).
	* src/iiwusynth.h (struct _iiwu_sample_t): Added 'amplitude_that_reaches_noise_floor_is_valid'
	and 'amplitude_that_reaches_noise_floor'

2002-07-13  Peter Hanappe  <peter@hanappe.com>
	* src/Makefile.am (EXTRA_libiiwusynth_la_SOURCES): Applied Takashi
	Iwai's patch. The configure stuff in iiwusynth-0.2 cannot be

	Previously, turning a volume pedal briefly to 0 would quit all voices playing.

	* src/iiwu_rev.c (iiwu_revmodel_processreplace): Removed 'dry' path from reverb unit 
	Motivation: This saves a couple of multiplications, the dry signal goes through the ordinary output
	anyway.

2002-04-30  Markus Nentwig  <nentwig@users.sourceforge.net>

	* src: Added iiwu_LADSPA.c, iiwu_LADSPA.h (support for LADSPA effect plugins).
	
	* src/iiwusynth.c (main): Changed default gain to 0.2.

	* src/iiwu_voice.c: Restructured the voice initialization as follows:
	(iiwu_voice_init): sample position, IIR filter history, envelopes etc. are reset.
	(iiwu_voice_optimize): The generators (nominal value) have been set by the sound font.
	Now each modulator is calculated once to obtain the 'final' initial value for each
	generator, which consists of nominal value and modulator-contributed part.
	(iiwu_voice_update_param): Calculates all voice parameters, which depend on one
	particular generator. This is called once for each voice parameter during 
	voice_optimize and further each time, when a modulator changes a generator.
	(iiwu_voice_update_param): Added a voice parameter filter_gain to avoid
	recalculating the filter gain each time the center frequency changes (it depends
	only on Q)
	(iiwu_voice_write): Voice is now turned off, when the amplitude falls below -100 dB,
	even during the sustain phase (happens, when holding a piano key for a very long time)

	* src/iiwu_voice.c (iiwu_voice_noteoff): Moved voice->chan = NO_CHANNEL into iiwu_voice_off.
	Previously a released note was not modulated anymore, for example pitch bend stopped working as soon
	as the key was released.

	* src/iiwu_voice.h: Changed _ON macro to figure out the state of a key from the position in
	the envelope, instead of using a cleared channel number as indicator.

	* src/iiwu_synth.c: Implemented all default modulators
	Added LADSPA support.
	Added digital clipping.
	Moved master gain factor ahead of LADSPA Fx.

	* src/iiwu_mod.c: 'Hardcoded' GM default modulator vel => filter.
	Replaced 128 with 127 in (127-x)

	* src/iiwu_midi.c: Fixed sysex for realtime MIDI. Fixed pitch bend bug.

	* src/iiwu_gen.c (iiwu_gen_set_default_values): Using float instead of int for default values.
	Added references to specifications (doc). Changed 'init array' function name to 'set_default' .

	* src/iiwu_defsfont.c (iiwu_preset_zone_import_sfont): Import of modulators
	(iiwu_inst_zone_import_sfont): Import of modulators
	(iiwu_defpreset_noteon): Added modulators, fixed generator problem (local zone overwrites global zone, previously it added)

	* src/iiwu_conv.c: Using now oncave / convex equation from SF specs.
	Removed ct2hz functions and tables.
	(iiwu_ct2hz): Limit checking
	(iiwu_cb2amp): Removed 'magic number'
	(iiwu_tc2sec): Avoided == for iiwu_real_t
	
	* src/iiwu_cmd.c: Increased number of tokens. Using WORKLINELENGTH constant.
	Changed max. gain to 5.
	Added LADSPA commands.
	Renamed misleading rev_bypass command to rev_enable

	* src/iiwu_chan.c: Centered pitch wheel. Added 'expression' modulator (CC 11).
	* configure.in: Added LADSPA support

	* src/iiwu_voice.c (iiwu_voice_write): turns off voice if
	amplitude < -100 dB in release phase. Set filter gain back to old
	value (0.25f * ...)

	* src/iiwuplay.c (main): added gain, interactive, and reverb options

	* src/iiwusynth.c (main): added gain and reverb options
