Re: [sc-users] Working with playbuf/trigger

[Sam Ingrassia <sam.ingrassia@xxxxxxxxx>]

Thanks for the help, t_trig and decay.kr worked out well!

Hi Sam, not really following you here (sorry insufficient sleep) but this sounds like it can be managed by using t_trig type arguments... Search for t_trig in SynthDef help file for more info.

SynthDef(\trigme, { arg t_trig1; Out.ar(0, SinOsc.ar(220, 0, Decay.kr(t_trig1, 0.1))); }).memStore;

a = Synth(\trigme);

a.set(\t_trig1, 1);

a.set(\t_trig1, 1);

a.set(\t_trig1, 1);

//and so on...

Sorry if that is irrelevant, hope that helps.

Thanks to everyone in advance -

MyApp.applicationData.at("KeyboardOperator").at("CurrentNodeProxy").source = { 

arg rate = 1, trigger = 0, startPos = 0, loop = 1;

//enable trigger

trigger = if(BinaryOpUGen('==', trigger, 1), Impulse.kr(MouseX.kr(0.5,100,0.5)), 0);

PlayBuf.ar(1,b,rate,trigger,startPos, loop).dup;

};

With the above code, when i set trigger to 1 i can then take control via impulse/MouseX to execute trigger. My question is, how can I just execute trigger just once? for instance doing something like this:

MyApp.applicationData.at("KeyboardOperator").at("CurrentNodeProxy").source = { 

arg rate = 1, trigger = 0, startPos = 0, loop = 1;

PlayBuf.ar(1,b,rate,trigger,startPos, loop).dup;

};

MyApp.applicationData.at("KeyboardOperator").at("CurrentNodeProxy").set(\trigger, 1);

MyApp.applicationData.at("KeyboardOperator").at("CurrentNodeProxy").set(\trigger, 0);

I would think that this would jump to the startPos and then continue playing, which is the behavior that I am trying to achieve. This leads me to believe that impulse is executing at a different time/context (which i do not fully understand yet) and modulating with the value from MouseX. How can I trigger a jump back just using NodeProxy.Set()?

Thanks again,

Sam
