Just read this thread: Aftertouch problem - #3 by iainmccurdy
@iainmccurdy I made a test instrument that uses midiin like you suggested:
<CsoundSynthesizer>
<CsOptions>
-n -d -+rtmidi=NULL -M0 -m0d --midi-key-cps=4 --midi-velocity-amp=5
</CsOptions>
<CsInstruments>
; Initialize the global variables.
sr = 44100
ksmps = 32
nchnls = 2
0dbfs = 1
massign 0, 1
;instrument will be triggered by keyboard widget
instr 1
kbnd pchbend 0, 48
kbnd portk kbnd, .01
kpchbend = semitone(kbnd)
iInstrchan midichn
kstatus,kchan,kdata1,kdata2 midiin
if (kstatus==208 && kchan==iInstrchan ) then
kAftouch = kdata1
endif
kAftouchnew portk kAftouch/127, .05
//printk2 kAftouchnew
kEnv madsr .01, .0, 1, 1
ares pluck p5, p4*kpchbend, p4*100, 0, 1
ares2 oscil kAftouchnew, p4*kpchbend
out (ares+(ares2*0.5)) * kEnv
endin
</CsInstruments>
<CsScore>
f0 z
</CsScore>
</CsoundSynthesizer>
This actually works better in Cabbage than QtCsound for me. The Seaboard in Csound is now starting to feel like a real instrument!
One question regarding portk is there a better way to smooth out the k signal, so that swells are nice and smooth? I have tried interp but that doesn’t seam to work. I can just set the k-rate to 1, but I would prefer to have something less taxing on computer for live performance.
@rorywalsh after reading more about Geert’s github I found SendMIDI. This looks like it can easily generate virtual MIDI streams, with lots of control data. Possibly this could be used to make a ‘virtual’ Seaboard (lots of MIDI channels & pitchbend, pressure etc…):
