	Hello, Could someone please help me understand what I need to modify in order to have each iteration of the loop on a k-period (so that I have a new value on every k period)? kcount=0 isize = ftlen(itable) loop: kout tab kcount, itable loop_lt kcount, 1, isize, loop printk2 kout (full CSD below) Many Thanks Peiman <CsoundSynthesizer> <CsOptions> -W -d -odevaudio </CsOptions> <CsInstruments> sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 opcode test,k, ki kval, itable xin kcount=0 isize = ftlen(itable) loop: kout tab kcount, itable loop_lt kcount, 1, isize, loop endop instr 1 itable ftgen 0, 0, 16, -7, 0, 16, 1 kline line 0, p3, 15 kout test kline, itable printk2 kout endin </CsInstruments> <CsScore> i1 0 10 </CsScore> </CsoundSynthesizer>

	I am not sure I understand your question, but in case this information is relevant, the whole instrument is a loop that is run through once per k cycle. For example: instr 1 kindex init 0 kindex = kindex+1 endin in the above instrument, kindex is 1 at the end of the first k cycle, 2 at the end of the second, etc. etc. On Fri, Jul 27, 2012 at 7:11 PM, peiman khosravi wrote: > Hello, > > Could someone please help me understand what I need to modify in order to > have each iteration of the loop on a k-period (so that I have a new value on > every k period)? > > > kcount=0 > isize = ftlen(itable) > > loop: > kout tab kcount, itable > > loop_lt kcount, 1, isize, loop > printk2 kout > > (full CSD below) > > Many Thanks > Peiman > > > > > > > > > -W -d -odevaudio > > > > sr = 44100 > kr = 4410 > ksmps = 10 > nchnls = 1 > > > > > opcode test,k, ki > kval, itable xin > > kcount=0 > isize = ftlen(itable) > > loop: > kout tab kcount, itable > > loop_lt kcount, 1, isize, loop > > endop > > > > > instr 1 > > itable ftgen 0, 0, 16, -7, 0, 16, 1 > > kline line 0, p3, 15 > > kout test kline, itable > > printk2 kout > > endin > > > > > > i1 0 10 > > >

	Hi Peiman, It looks like you are missing an xout in you UDO.

	Thanks Steven, that was missed out as I was changing things around a bit but it wasn't the main problem. Justin, your example is exactly what I needed. Thanks very much. After all these years with Csound I couldn't figure this one out! P On 28 July 2012 06:37, Steven Yi <stevenyi@gmail.com> wrote: Hi Peiman, It looks like you are missing an xout in you UDO.
