This example is an interactive demo that uses MIDI data from the MIDI
In jack to drive a simple musical instrument. Unlike linmidi, several
controllers (Mod wheel, pitch bend wheel, channel volume) are used by
the linbuzz patch, via the sfront/lib/Slib library.
The test this program under Linux, type "make" in this directory to
run the example.
To test this program under Macintosh OS X, copy the Makefile.osx file
to Makefile, and then type "make". Note that sfront supports external
MIDI sources via CoreMIDI at present, but not virtual MIDI sources.
Testing under Windows MultiMedia Extension library
--------------------------------------------------
Note that this example has not been tested yet under Windows;
please send back bugs and performance reports. Thanks!
The simplest test under Microsoft Windows uses the Windows MultiMedia
Extension library, via the PortAudio library. First, run sfront:
sfront -cin win32 -aout pa_win_wmme -orc linbuzz.saol -sco linbuzz.sasl
And then compile the sa.c file using either gcc:
gcc -O3 sa.c -lm -lwinmm -o sa.exe
or Microsoft Visual C++:
cl sa.c winmm.lib -o sa.exe
Execute the sa.exe file to start the instrument. Rerun sfront using
the -latency t flag, where t is a floating-point constant with units of
seconds, to test the latency behavior of the program.
Testing under Windows DirectSound
---------------------------------
Sfront also supports the Windows DirectSound system, via the Portaudio
library. To use DirectSound, you'll need a recent version of Developer
Microsoft Directsound installed on your machine, available from
http://www.microsoft.com/directx/download.asp
To use sfront with Directsound, first run sfront:
sfront -cin win32 -aout pa_win_ds -orc linbuzz.saol -sco linbuzz.sasl
And then compile the sa.c file using Microsoft Visual C++:
cl sa.c dsound.lib dxguid.lib winmm.lib -o sa.exe
Execute the sa.exe file to start the instrument. Rerun sfront using
the -latency t flag, where t is a floating-point constant with units of
seconds, to test the latency behavior of the program.
If you have trouble with compilation, see this FAQ for DirectSound
installation issues:
http://msdn.microsoft.com/library/default.asp?URL=/library/techart/DirectX8faq.htm
Note gcc probably won't compile DirectSound, but you can try it using:
gcc -O3 sa.c -lm -lwinmm -ldsound -ldxguid -lwinmm -o sa.exe
