Subject[Csnd] k-rate pchbend
Why am I not able to get the pchbend information as I do the mod wheel?

-Charles



-odac -b64 -B256 -M0



sr = 44100
ksmps = 8

     instr 1
kbnd pchbend        ;pitch bend
kmod chanctrl 1,1   ; mod wheel

printk2 kbnd
printk2 kmod

     endin

The note needs to have been activated by MIDI for pchbend to work. I'm not sure why this has been done so.
You could use midiin instead, Something like this will work:

<CsoundSynthesizer>
<CsOptions>
-odac -b64 -B256 -M0
</CsOptions>
 
<CsInstruments>
sr = 44100
ksmps = 8

instr    1
kstatus, kchan, kdata1, kdata2 midiin
if kstatus = 224 then
    printk2 kdata2
endif
kmod chanctrl 1,1   ; mod wheel
printk2 kmod
     endin
 
</CsInstruments>
<CsScore>
i1 0 3600
e
</CsScore>
</CsoundSynthesizer>


It is of course only reading one of the data bytes. My cheapo MIDI controller only outputs 7-bit resolution anyway. If you have higher resolution hardware and want to use it you will have to recombine the two data bytes.
