Subject	[Csnd] loopseg syntax
	Please help to me to correctly understand the syntax of loopseg. I am puzzled by my code that was working as I expect, but as I have a warning message "wrong number of argument", I am trying to figure out how to correctly code loopseg. For this I am trying this little code extracted from the doc From the manual ksig loopseg kfreq, ktrig, iphase, ktime0, kvalue0 [, ktime1] [, kvalue1] \ [, ktime2] [, kvalue2] [...] But the following code display only one value change, not what is expected <CsoundSynthesizer> <CsOptions> -iadc0 -odac0 -b1024 </CsOptions> <CsInstruments> sr = 44100 ksmps = 1 nchnls = 2 instr 300 klp loopseg 10, 0, 0, 0,0, 1,1, 1, 0 printk2 klp endin </CsInstruments> <CsScore> i300 0 20 </CsScore> </CsoundSynthesizer> I understand the parameters as loop frequency of 10 Hz, no retrigger, phase 0 (start immediately), first segment 0,0 - 2nd segment 1,1 - third segment 1,0 I understand (and maybe I am wrong here): value starts at 0, then increases to 1, then go back to 0, each time interval is the same and is 1/3 of 1/10 seconds By changing to klp loopseg 10, 0, 0, 0,1, 1,1, 0, 0 printk2 displays many different values, but the meaning is loop frequency of 10 Hz, no retrigger, phase 0 (start immediately), first segment 0,1 - 2nd segment 1,1 - third segment 0,0 Thanks

	which version of csound, and of the manual, do you use? there was a change / correction, in 5.13 as i just read. iain has some examples and explanations here: http://en.flossmanuals.net/csound/a-envelopes/ have a look at 05A10_lpshold_loopseg.csd. best - joachim Am 05.09.2013 15:07, schrieb jean-pierre lemoine: > Please help to me to correctly understand the syntax of loopseg.

	Thanks Joachim for looking at this question. I am using the csound 6 documentation. Where the phase parameter must be? after the trigger parameter or at the end? Base on my test, this is working only at the end, which is not what the documentation describes. If I decode the example you suggest to look at, I interpret, assuming that ktemp must be related to a time value trigger =0 pair 1 = 0,0 pair 2 = 0.1, 1 pair 3 = 55/kTempo, 1 pair 4 = 0.1, 0 pair 5 = 5/kTempo, 0 phase = 0 Phase is at the end kAmpEnv loopseg kBtFreq, 0, 0, 0,0.1, 1, 55/kTempo, 1, 0.1,0, 5/kTempo,0,0 On Thu, Sep 5, 2013 at 8:07 PM, joachim heintz <jh@joachimheintz.de> wrote: which version of csound, and of the manual, do you use? there was a change / correction, in 5.13 as i just read. iain has some examples and explanations here: http://en.flossmanuals.net/csound/a-envelopes/ have a look at 05A10_lpshold_loopseg.csd. best - joachim Am 05.09.2013 15:07, schrieb jean-pierre lemoine: Please help to me to correctly understand the syntax of loopseg.
