I understand all this, and believe I have taken it into account. The synth is still existing at the time the .sched is evaluated since the code is designed such that the synth will not release until after the next event is called. In fact if I adjust the code to check I can still hear the event. As I wrote, this is only a problem when this event is not the first one. If it is the first one, then it works fine, with exactly the same code, and levels of spawning. If it isn't the first one, then the .sched gets evaluated immediately. This is what confuses me. It seems as if the tempo is initially very high for some reason, but as I wrote before it doesn't matter if I comment out the tempo related lines of code. The problem seems to be scheduling with the local synth if it's not the first event spawned. So not that it doesn't get evaluated, but that it gets evaluated (seemingly) right away. > Is the TSpawn supposed to be triggering an entire series of events with an > independant tempo stream? If so then you do need one more level of spawning. No, this event alone (let's call it A) has an independant tempo stream, but the next event needs to be spawned at a certain point in the progression of event A. The next event is in the master tempo stream again. I can't adjust the tempo of the master Synth, since this will affect things that are already happening, and I don't want to do that. I'll try another level of spawning though. Thanks, S. ------------------------------ Date: Mon, 09 Jul 2001 21:07:32 -0500 From: James McCartney <---@---.---> Subject: Re: .sched?

The slots in the output routing array represent the hardware channels. The index you supply tells it which software channel to stuff into that output. This way, one software channel can go out multiple outputs. So your array should look like this: Synth.setOutputRouting([1, 2, 3, 4, 5, 6, 7, 8, 1, 2, 3, 4, 5, 6, 7, 8]); The slots in the input routing array represent the software input channels. The index you supply tells it which hardware channel to stuff into that input. This allows one hardware channel to go to multiple software inputs.

(but correct me if i'm wrong...) an example perhaps? or did you mean that you could simply declare a whole bunch of arguments (or variables) and simply not use them? in that case, you're not really using them as place holders. you're simply not using them at all. it might be better to not do this. cheers, christian ------------------------------ Date: Tue, 10 Jul 2001 21:11:14 -0500 From: James McCartney <---@---.---> Subject: Re: arg i ? on 7/10/01 8:02 PM, christian adam hresko at godpup@ix.netcom.com wrote: > or did you mean that you could simply declare a whole bunch of arguments (or > variables) and simply not use them? in that case, you're not really using > them > as place holders. you're simply not using them at all. it might be better to > not do this. You misunderstand I think. In the case of places where you provide a function to be called by the system, you are passed a certain number of arguments in a certain order. You have no control over the number of arguments or the order. That is defined by the code calling you. If you want to get access to the third argument for example but do not care about the first two, you have to declare three arguments. The names can be anything but the fact that you are getting passed three arguments: the spawn, the event count, and the synth, is not under your control by declaring the argument list. - --- james mccartney james@audiosynth.com SuperCollider - a real time synthesis programming language for the PowerMac. ------------------------------ Date: Tue, 10 Jul 2001 20:30:59 -0600 From: David Cottle <---@---.---> Subject: Re: arg i ? > on 7/10/01 8:02 PM, christian adam hresko at godpup@ix.netcom.com wrote: > >> or did you mean that you could simply declare a whole bunch of arguments (or >> variables) and simply not use them? in that case, you're not really using >> them >> as place holders. you're simply not using them at all. it might be better >> to >> not do this. > > You misunderstand I think.

And the only way to get to e.g., event count, is to declare spawn, then count. Even if you don't use spawn, even though you name them anything you want. For example: [10, 20, 30].do({arg count; count.postln;}) will not post the count, but the items in the array. [10, 20, 30].do({arg placeholder, count; count.postln;}) will post the count, not the items. If, for whatever reason, I want to use count but not the items in the array, I have to declare the first argument as a placeholder. ------------------------------ Date: Tue, 10 Jul 2001 23:18:17 -0400 From: christian adam hresko <---@---.---> Subject: Re: arg i ?
