	Is there a way to turn off a metro opcode once it has started?

	not sure what you mean by "once it has started". this works ... -odac instr 1 kGo init 1 if kGo == 1 then kTrig metro 1 else kTrig = 0 endif printk2 kTrig kGo = 0 endin i 1 0 10 ... but actually then there is no sense to use metro, but this: if kGo == 1 then kTrig = 1 else kTrig = 0 endif best - joachim Am 19.10.2013 16:26, schrieb Roger Kelly: > Is there a way to turn off a metro opcode once it has started? > >

	I think these are all good solutions. I should explain better the context of my question. I am developing an Android application and using "metro" as a 'tick' trigger to do various graphic animations. The Android app gets updates from Csound per "metro" frequency tick. I had considered "turning off" metro over concern of CPU usage when animations are off. But perhaps there is no real overhead of a metro opcode? Does anyone know if metro incurs much of a CPU cost?
