[Csnd] can't print global i-variable

| Dear community, in order to prevent samples out of range I want to print the value of the global amplitude in a midi-triggered csd-file. The problem: the file uses additive-synthesis and the amplitude for the individual partials comes out off a ftable. Unfortunately I didn't succeed with my attempt. Only at the very beginning I get the message: instr 102: giAmp = 0.000(before I've touched any key). Here is my simplified code, hope it's not too long: ;;;;;;;;;;;;;;;;;;;;;;;;;; SNIPPET ;;;;;;;;; <CsoundSynthesizer> <CsOptions> -odevaudio -Ma </CsOptions> ; ============================================== <CsInstruments> sr = 48000 ksmps = 1000 nchnls = 2 0dbfs = 1 giAmp init 0 gisine ftgen 0,0,2^10, 10, 1 giAmpCurve ftgen 0,0,128,-16,1,128,2,0 ; curve for Amplitude of the partials giratiotab ftgen 0,0,-6,-2,1,2,3,4,5,6 ; ratios of the partials instr 1 imaxdur = 1 imaxamp ampmidi 0.1 icps cpsmidi iatt = 0.1 ipartnumber = 1 inumparts = 6 isubinstr = 101+icps/sr ;;;;;;;;;;;;;;;;;;;;;;;; LOOP STARTS ;;;;;;;;;;;;;;;;;;;;;;;;;;;; loop: ;;;;;;;;;;;;;;;;;;;;;;;;;; frequencies ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; iratio table ipartnumber-1, giratiotab ipartfreq = iratio * icps ;;;;;;;;;;;;;;;;;;;;;;;;; amplitudes ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ipartamp table (ipartnumber-1)/(inumparts-1),giAmpCurve,1 ipartamp = ipartamp*imaxamp ;;;;;;;;;;;;;;;;;;;;;;;;;; duration ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ipartdur = imaxdur/ipartnumber ;;;;;;;;;;;;;;;;;;;;;;;;; attack ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ipartatt = iatt/ipartnumber ;;;;;;;;;;;;;;;;;;;;;;;; send it to subinstrument ;;;;;;;;; event_i "i", isubinstr, 0, ipartdur, ipartfreq, ipartamp, ipartatt loop_le ipartnumber, 1, inumparts, loop ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; END OF LOOP ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; endin instr 101 ipartdur = p3 ipartfreq = p4 ipartamp = p5 giAmp = ipartamp+giAmp ipartatt = p6 asig poscil ipartamp, ipartfreq, gisine ;;; envelope adec linseg 0,ipartatt,0,ipartdur-ipartatt,-98 aenv = ampdb(adec) ;;; output aout = aenv*asig outs aout, aout endin instr 102 ; reads the accumulated Amplitudes of the partials and prints it print giAmp endin </CsInstruments> ; ============================================== <CsScore> f 0 10 i1 0 10 i102 0 10 </CsScore> </CsoundSynthesizer> |

| Hi Stefan, I suppose the giAmp is changing on a note-to-note basis and you want to print these changes? You need to convert it to krate in this case and use printk2 instead: (instr 101) giAmp = ipartamp+giAmp gkamp init giAmp (instr 102) printk2 gkamp Best, Peiman On 5 August 2012 11:42, Stefan Thomas <kontrapunktstefan@gmail.com> wrote: Dear community, |

| Dear peiman, thanks for Your explanations. Yes, giAmp changes on a note-to-note basis and I thought, that this variable can change when pressing a key. I've adopted Your proposals and it works now as desired! 2012/8/5 peiman khosravi <peimankhosravi@gmail.com> Hi Stefan, |

| Sorry, I would like to ask one more question. I get the following terminal's output: i102 0.37523I would like to change it to: How can I achieve it?gkamp 0.37523 2012/8/5 peiman khosravi <peimankhosravi@gmail.com> Hi Stefan, |

| Hello, You can use printks instead. Something like this: printks "giamp = %f\n", 0, gkamp "%f" means take the value of gkamp and print it as a float. "\n" is a newline, otherwise everything is printed on the same line. Best, P On 5 August 2012 13:59, Stefan Thomas <kontrapunktstefan@gmail.com> wrote: Sorry, I would like to ask one more question. |
