MCLAR -- clarinet physical model
in RTcmix/insts/stk

quick syntax:
MCLAR(outsk, dur, AMP, FREQ, NOISEAMP, maxpressure, REEDSTUFF[, PAN, BREATHENV]) 

   p0 = output start time (seconds)
   p1 = duration (seconds)
   p2 = amplitude (absolute, for 16-bit soundfiles: 0-32768)
   p3 = frequency (Hz)
   p4 = noise gain (0.0-1.0)
   p5 = max pressure (0.0-1.0)
   p6 = reed stiffness (0.0-1.0)
   p7 = pan (0-1 stereo; 0.5 is middle) [optional; default is 0.5]
   p8 = breath pressure table [optional; default is 1.0]

   p2 (amplitude), p3 (frequency), p4 (noise amp), p6 (reed stiffness) and
   p7 (pan) can receive dynamic updates from a table or real-time control source.
   p8 (breath pressure table), if used, should be a reference to a pfield table-handle.

MCLAR is the "Clarinet" physical model in Perry Cook and Gary Scavone's STK, the Synthesis ToolKit.



Usage Notes

MCLAR implements a clarinet physical model. It seems highly similar to the earlier CLAR physical model, but this has better control parameters. Also check out MBLOWHOLE for a clarinet-like model with a tonehole and register vent included.

It was originally adapted from Perry Cook and Gary Scavone's STK, for doing amazing physical model stuff.

This is from the orginal STK source code for "Clarinet":

Be aware that some combinations of parameters will yield no sound. The 'physics' have to work correctly!

The optional 'breath pressure table' (p8, "BREATHENV") functions independently of an amplitude-control envelope used in p2 ("AMP"). This allows you to design sharp attacks, etc.

MCLAR can produce other mono or stereo output.



Sample Scores

very basic: 

   rtsetparams(44100, 2)
   load("MCLAR")

   breathenv = maketable("line", 1000, 0,1, 2,0)
   MCLAR(0, 3.5, 30000.0, 314.0, 0.2, 0.7, 0.5, 0.5, breathenv)
   MCLAR(4, 3.5, 30000.0, 149.0, 0.2, 0.7, 0.5, 0.5, breathenv)


slightly more advanced: 
   rtsetparams(44100, 2)
   load("MCLAR")

   amp = maketable("line", 1000, 0,0, 1,1, 2,1, 3,0)
   freq = maketable("line", "nonorm", 1000, 0, 349, 1, 207)
   MCLAR(0, 3.5, amp*20000.0, freq, 0.2, 0.7, 0.5)

   bamp = maketable("line", 1000, 0,1, 2,1, 3,0)
   noise = makeLFO("sine", 7.0, 0.0, 1.0)
   reedstiff = maketable("line", 1000, 0,0, 1,1, 2,0)
   pan = maketable("line", 1000, 0,1, 1,0, 1.5,1, 2,0)
   MCLAR(4, 3.5, 15000.0, 149.0, noise, 0.7, reedstiff, pan, bamp)
