	Victor (and Adam - thanks to both), Believe it or not, this doesn't work either. I also can't understand why my score line: i1 0 -1 creates a distill.wav file that contains no samples (just a 44-byte header). I have found one cumbersome procedure that works: instrument 1, of momentary duration, determines the duration of sample one, subtracts 1 (or less) from it, and spawns instrument 2 with that duration. Instrument 2 is then the controller that instigates samples 1 and 2 (now instruments 3 and 4). No turnoffs now necessary, as the duration for the controlling instrument is preset appropriately. If anyone has a simpler and more straightforward solution, I'd be glad to hear it. Adam - Sorry, I don't quite understand what you are suggesting, with manual overlapping and all. Sounds like you are thinking of a completely different approach. If you've an example, I'd love to see it.

	Hi Art, I haven't followed this email thread too closely, but have you thought to rewrite p3 in instr 2 and instr 3, using filelen? Something like: instr 2 instr 2 Sfile = p4 ilen1 filelen Sfile p3 = ilen1 kamp linseg 0, .5, 1, p3 - 2, 1, 1.5, 0 aout diskin Sfile, 1 out aout * kamp endin and possibly reusing that for both wavs. It'd mean you wouldn't have to worry about turning off anything as the instrument would just end at the file length. Haven't tried this, but seems like a possibility? steven On Tue, Jan 29, 2013 at 10:33 PM, Art Hunkins wrote: > Victor (and Adam - thanks to both), > > Believe it or not, this doesn't work either. > > I also can't understand why my score line: > i1 0 -1 > creates a distill.wav file that contains no samples (just a 44-byte header). > > I have found one cumbersome procedure that works: > instrument 1, of momentary duration, determines the duration of sample one, > subtracts 1 (or less) from it, and spawns instrument 2 with that duration. > Instrument 2 is then the controller that instigates samples 1 and 2 (now > instruments 3 and 4). > No turnoffs now necessary, as the duration for the controlling instrument is > preset appropriately. > > If anyone has a simpler and more straightforward solution, I'd be glad to > hear it. > > Adam - Sorry, I don't quite understand what you are suggesting, with manual > overlapping and all.

	art - i am pretty sure that there is a simple solution for what you want to do. my problem is that from your description: "It is mixing two mono samples; the second slightly overlaps the first." i cannot get a clear image of the situation. some questions: - do they start at the same time? - or at any different, but fixed time? - or does sample 2 start at any time in a real-time situation? - do you want to record sample 1 until sample 2 begins, or do you want to record both until one of them ends? sorry if this is due to my poor understanding, but if you don't mind, explain again. best - joachim Am 29.01.2013 23:33, schrieb Art Hunkins: > Victor (and Adam - thanks to both), > > Believe it or not, this doesn't work either. > > I also can't understand why my score line: > i1 0 -1 > creates a distill.wav file that contains no samples (just a 44-byte > header). > > I have found one cumbersome procedure that works: > instrument 1, of momentary duration, determines the duration of sample > one, subtracts 1 (or less) from it, and spawns instrument 2 with that > duration.
