Thank you, Istvan. This is exactly the information I needed.
For list verbosity and for the purposes of the various archives and
Nabble.com and elsewhere, here is the complete implementation, with
Csound files and commandline options.
Example 1 commandline used:
[localhost:~] user% /Users/you/CVS/csound5/csound -odac -iadc -d -M0
-+rtaudio=Jack -+jack_client=csound5-1 ~/Desktop/glovescale.csd
;// Example 1 - Signal generator
;// called "csound5-1" for the Jack server.
sr = 44100
kr = 44100
ksmps = 1
nchnls = 2
itmp ftgen 1, 0, 16384, 10, 1
;// This header contains references to all UDOs on the repository
#include "_udo.h"
;// http://www.csounds.com/udo
/*--- ---*/
instr 1
/* substitute with midi control if you do not have a p5 glove ! */
ka, kb, kc, kf1, kf2, kf3, kf4, kf5, kx, ky, kz p5glove
;// scale raw input in range 0-1
kavg = (((kf1+kf2+kf3+kf4+kf5)/5)/63)
kzee = ((kz+400)/800)
/* */
;// rescale to desired range
kscl scale kavg, 4.0, 12.0
kscl2 scale kzee, 0, 8
;// volume control
kamp ctrl7 1, 7, 0, 150
kvol gainslider kamp
;// sound synthesis
aosc oscil 12000, cpspch(kscl), 1
aset waveset aosc, kscl2-1
aout = aset*kvol
aclp clip aout, 2, 32767
; printk2 kscl ; for debugging
outs aclp, aclp
endin
/*--- ---*/
;// fun !
i1 0 1000
e
; # EOF
Example 2 commandline used:
[localhost:~] user% /Users/you/CVS/csound5/csound -odac -iadc -d -M0
-+rtaudio=Jack -+jack_client=csound5-2 ~/Desktop/glovescale.csd
;// Example 2 - Process the previous input using the mod wheel
;// to alter pitch
sr = 44100
kr = 44100
ksmps = 1
nchnls = 2
itmp ftgen 1, 0, 16384, 20, 9, 1
/*--- ---*/
instr 1
ainl, ainr ins
kscl ctrl7 1, 1, -12, 12
kscl = (2^(kscl/12))
fl pvsanal ainl, 8192, 8192/4, 8192, -1
fr pvsanal ainr, 8192, 8192/4, 8192, -1
fscl pvscale fl, kscl
fscr pvscale fr, kscl
a0l pvsynth fscl
a0r pvsynth fscr
acll clip a0l, 2, 32767
aclr clip a0r, 2, 32767
outs acll, aclr
endin
/*--- ---*/
i1 0 1000
e
; #EOF
Thanks again, Istvan, for this valuable addition to the language !
