Stopping a Pattern

[macduff111]

Hi,
I can now send patterns to synthdefs, and am excited that I can control scsynth from python! I never got on with sclang, but scsynth is v powerful with a great architecture.
Anyway, my question - how do I stop a Pattern once it has been started with play() ?
Thanks

Save a reference to the pattern player and call .stop() on it:

player = my_pattern.play(...)
player.stop()

Patterns themselves are just stateless iterables. When you call my_pattern.play() you're creating a PatternPlayer object which maintains the state of iteration through the pattern, and coordinates between that iterator, the clock, and the synthesis execution context (typically a Server).

Also, nit about verbiage. SynthDefs don't receive anything. Think of them like classes or templates. When you issue a /s_new command under the hood, you're allocating an instance of the SynthDef. That occurs e.g. when an EventPattern's NoteEvent gets performed against the execution context by the pattern player.

Yes, understood, my terminology a bit loose. "I can select which SynthDef a Pattern binds to" would be better way of putting it perhaps.
