I noticed something while using the Zak opcodes to route audio from multiple instruments to a single output, and subsequently got the same problem when trying it with global audio signals. The following code will generate a random sequence of notes on each bang of the metro, with the notes ringing out over eachother: instr trigger ktrig metro 0.2 ktime init 0 if (ktrig == 1) then while (ktime <= 1) do ; For 1 second krand random 0, 7 knote table krand, 1 ; Pick a random MIDI note from a table event "i", 2, ktime, 0.5, knote ktime += 0.1 ; Increment our time od ktime = 0 ; Reset the timer endif endin instr 2 kenv madsr 0.01, 0.01, 0.5, 1 kfreq = cpsmidinn(p4) asig pluck kenv, kfreq, i(kfreq), 0, 1 outs asig, asig endin </CsInstruments> <CsScore> f1 0 7 -2 60 62 64 65 67 69 71 i"trigger" 0 20 </CsScore> </CsoundSynthesizer> However, when the audio is routed using the Zak opcodes such as this (with zak initialised and the output instrument turned on of course): instr 2 kenv madsr 0.01, 0.01, 0.5, 1 kfreq = cpsmidinn(p4) asig pluck kenv, kfreq, i(kfreq), 0, 1 zaw asig, 0 endin instr output asig zar 0 outs asig, asig zacl 0, 1 endin Or when the output of pluck is assigned to a global a rate which is then output in the output instrument, each quick successive note will cut the previous one off entirely. This happens whether zacl is used to clear the variable in zak space or not, or whether the global is cleared or not after the output. I can't figure out why this would happen, maybe it's a bug? Or maybe someone could explain it to me. Cheers! Ryan |

You need to accumulate in zak not just write
