[Csnd] Help with loop and ctrl7

Subject[Csnd] Help with loop and ctrl7
I am currently trying to load a bank of 48 pots with this loop that puts the
ctrl7 into an array. It is basically iterating between CCs 13-24 on channel
1, then doing the same on channel 2 up through channel 4.

It prints out the correct values but the 'printk2 gklfo[0]' isn't printing
anything when the knob is turned. 

gklfo[] init 48
index init 0
ichn init 1
imaxchan = 4 ;max channel to count
iccmin = 13 ;min pot cc number
iccmax = 24 ; max pot cc number
loadchn:
if (ichn <= imaxchan) then
	icc = iccmin 
		loadcc:
		if (icc <= iccmax)then
			initc7	ichn, icc, 0	
			gklfo[index] ctrl7 ichn, icc, 0, 1
			icc += 1	
			index +=1
			goto loadcc
		endif
ichn += 1
goto loadchn
endif

printk2 gklfo[0]


However, if I simply put 

gklfo[0] ctrl7 1, 13, 0, 1
printk2 gklfo[0]

it prints fine when the knob is turned. Is an array the wrong way to
approach this?

Thanks

Your loop is an itime loop but ctrl7 is a perf-time action

One way to address the issue is making a simple instrument that
processes one channel, but initialize many instances from a separate
UDO or instrument, something like:

=====

instr CCProc
  index = p4
  ichn = p5
  icc = p6
  initc7  ichn, icc, 0
  gklfo[index] ctrl7 ichn, icc, 0, 1
endin

opcode StartCCProc
  index init 0
  ichn init 1
  imaxchan = 4 ;max channel to count
  iccmin = 13 ;min pot cc number
  iccmax = 24 ; max pot cc number

  while(ichn < imaxchan) do
    icc = iccmin

    while(icc < iccmax) do
      schedule("CCProc", 0, -1, index, ichn, icc)
       icc += 1
       index += 1
    od
    ichn += 1
  od
endop

StartCCProc()

=====

(Haven't tested above, but I think something like that would work)
