<U>DESCRIPTION</U></H4>
Get a value from the MIDI event that activated this instrument, or from
a continuous MIDI controller, and convert it to a locally useful format.
<H4>
<U>INITIALIZATION</U></H4>
<I>iscal</I> - I-time scaling factor.
<P><I>ifn</I> (optional) - function table number of a normalized translation
table, by which the incoming value is first interpreted. The default value
is 0, denoting no translation.
<P><I>inum, ictlno </I>- MIDI controller number.
<P><I>initial</I> - the <I>initial</I> value of the controller.
<P><I>ilow, ihigh</I> - low and hi ranges for mapping
<P><I>irange</I> - the pitch bend range in semitones.
<P><I>ichnl, ichnkm</I> - the midi channel<BR>
<BR>
<BR>
<H4>
<U>PERFORMANCE</U></H4>
<B>notnum</B>, <B>veloc</B> - get the MIDI byte value (0 - 127) denoting
the note number or velocity of the current event.
<P><B>cpsmidi</B>, <B>octmidi</B>, <B>pchmidi</B> - get the note number
of the current MIDI event, expressed in cps, oct, or pch units for local
processing.
<P><B>cpsmidib</B>, <B>octmidib</B>, <B>pchmidib</B> - get the note number
of the current MIDI event, modify it by the current pitch-bend value, and
express the result in cps, oct, or pch units. Available as an I-time value
or as a continuous ksig value.
<P><B>ampmidi</B> - get the velocity of the current MIDI event, optionally
pass it through a normalized translation table, and return an amplitude
value in the range 0 - <I>iscal</I>.
<P><B>aftouch</B>, <B>chpress</B>, <B>pchbend</B> - get the current after-touch,
channel pressure, or pitch-bend value for this channel, rescaled to the
range 0 - <I>iscal</I>. Note that this access to pitch-bend data is independent
of the MIDI pitch, enabling the value here to be used for any arbitrary
purpose.
<P><B>midictrl</B> - get the current value (0 - 127) of a specified MIDI
controller.
<P><B>midictrlsc</B> - get a scaled and offset value of a controller.
<P><B>chanctrl</B> - Get the current value of a controller and optionally
map it onto specified range. <I>ichnl</I> is the MIDI channel and
<I>ictlno</I> is the MIDI controller number.
<P><B>ctrlinit</B> - Sets initial values for a set of MIDI controllers.
