	hey csound community, i'm trying to get an array of strings to print on the signal ktrig using printf in a while loop. in this construction, it seems only the first iteration gets printed. is there a better way to do this? kelly output: new alloc for instr 1: :1,0 :1,0 :1,0 :1,0 :1,0 :1,0 :1,0 :1,0 :1,0 :1,0 B 0.000 .. 10.000 T 10.000 TT 10.000 M: 0.0 0.0 csd: sr =44100 kr =4410 ksmps =10 nchnls =2 instr 1 ktrig metro 1 kitr = 0 Sout =":" while kitr < 2 do printf "%s%d,%d\n", ktrig,Sout,ktrig,kitr kitr +=1 od endin i1 0 10 Csound mailing list Csound@listserv.heanet.ie https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND Send bugs reports to https://github.com/csound/csound/issues Discussions of bugs and features can be posted here

	not sure what you exactly want to do (print only when metro is 1?) but i think the second argument of your printf should be kitr+1, not ktrig. best - joachim On 07/03/2020 17:29, kelly hirai wrote: > hey csound community, > > i'm trying to get an array of strings to print on the signal ktrig using > printf in a while loop. in this construction, it seems only the first > iteration gets printed. is there a better way to do this? > > kelly > > output: > > new alloc for instr 1: > :1,0 > :1,0 > :1,0 > :1,0 > :1,0 > :1,0 > :1,0 > :1,0 > :1,0 > :1,0 > B 0.000 .. 10.000 T 10.000 TT 10.000 M: 0.0 0.0 > > csd: > > > > sr =44100 > kr =4410 > ksmps =10 > nchnls =2 > > instr 1 > ktrig metro 1 > > kitr = 0 > Sout =":" > while kitr < 2 do > printf "%s%d,%d\n", ktrig,Sout,ktrig,kitr > kitr +=1 > od > endin > > > > i1 0 10 > > > > Csound mailing list > Csound@listserv.heanet.ie > https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND > Send bugs reports to > https://github.com/csound/csound/issues > Discussions of bugs and features can be posted here Csound mailing list Csound@listserv.heanet.ie https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND Send bugs reports to https://github.com/csound/csound/issues Discussions of bugs and features can be posted here

	Setting kitr to zero every perf cycle is a little odd too Maybe.... ⁣Sent from TypeApp On Mar 7, 2020, 16:30, at 16:30, kelly hirai wrote: >hey csound community, > >i'm trying to get an array of strings to print on the signal ktrig >using >printf in a while loop. in this construction, it seems only the first >iteration gets printed. is there a better way to do this? > >kelly > >output: > >new alloc for instr 1: >:1,0 >:1,0 >:1,0 >:1,0 >:1,0 >:1,0 >:1,0 >:1,0 >:1,0 >:1,0 >B 0.000 .. 10.000 T 10.000 TT 10.000 M: 0.0 0.0 > >csd: > > > >sr =44100 >kr =4410 >ksmps =10 >nchnls =2 > >instr 1 > ktrig metro 1 > > kitr = 0 > Sout =":" > while kitr < 2 do > printf "%s%d,%d\n", ktrig,Sout,ktrig,kitr > kitr +=1 > od >endin > > > >i1 0 10 > > > >Csound mailing list >Csound@listserv.heanet.ie >https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND >Send bugs reports to > https://github.com/csound/csound/issues >Discussions of bugs and features can be posted here Csound mailing list Csound@listserv.heanet.ie https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND Send bugs reports to https://github.com/csound/csound/issues Discussions of bugs and features can be posted here

	There is a printarray opcode, but it doesn't seem to work for strings. Maybe you can file a ticket for that in the github issue tracker ;) Opcodes with an internal state can't be run in a loop like this but I've no idea if that's the case with printf. Either way, when I hit these issues I always reach for the old recursive UDO to resolve them. And it works here too... opcode printMyArray, 0, k[]o kArray[], iCnt xin kTrig metro 1 iArrayLen = lenarray:i(kArray) printf "%d:%d\n", kTrig,iCnt,kArray[iCnt] if iCnt < iArrayLen-1 then printMyArray kArray, iCnt+1 endif endop instr 1 kArray[] fillarray 1,7,5 printMyArray kArray endin On Sun, 8 Mar 2020 at 19:36, kelly hirai <khirai@hiraimusic.net> wrote: `shouldn't the output be` `:1,0` `:1,1` `repeated 10 times? ultimately i'm trying to get an array of strings dynamically printed to the console on the signal from ktrig. the fillarray manual entry uses unrolled printks:` instr 1 kS[] fillarray 1,7,5 printk 0, kS[0] printk 0, kS[1] printk 0, kS[2] turnoff endin `how would you do this with iteration?` `k.` On 3/7/20 3:06 PM, John ff wrote: Setting kitr to zero every perf cycle is a little odd too Maybe.... ⁣Sent from TypeApp On Mar 7, 2020, 16:30, at 16:30, kelly hirai <khirai@hiraimusic.net> wrote: hey csound community, i'm trying to get an array of strings to print on the signal ktrig using printf in a while loop. in this construction, it seems only the first iteration gets printed. is there a better way to do this? kelly output: new alloc for instr 1: :1,0 :1,0 :1,0 :1,0 :1,0 :1,0 :1,0 :1,0 :1,0 :1,0 B 0.000 .. 10.000 T 10.000 TT 10.000 M: 0.0 0.0 csd: <CsoundSynthesizer> <CsInstruments> sr =44100 kr =4410 ksmps =10 nchnls =2 instr 1 ktrig metro 1 kitr = 0 Sout =":" while kitr < 2 do printf "%s%d,%d\n", ktrig,Sout,ktrig,kitr kitr +=1 od endin </CsInstruments> <CsScore> i1 0 10 </CsScore> </CsoundSynthesizer> Csound mailing list Csound@listserv.heanet.ie https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND Send bugs reports to https://github.com/csound/csound/issues Discussions of bugs and features can be posted here Csound mailing list Csound@listserv.heanet.ie https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND Send bugs reports to https://github.com/csound/csound/issues Discussions of bugs and features can be posted here Csound mailing list Csound@listserv.heanet.ie https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND Send bugs reports to https://github.com/csound/csound/issues Discussions of bugs and features can be posted here Csound mailing list Csound@listserv.heanet.ie https://listserv.heanet.ie/cgi-bin/wa?A0=CSOUND Send bugs reports to https://github.com/csound/csound/issues Discussions of bugs and features can be posted here
