Hey thanks dick for everything but i still got some problems

when i change my sawbass arg note to freq to have iannix’s triggerIndex control it’s pitch it just clips and crashes…
hmm don’t get much on how Iannix messages works and the one you wrote either
or perhaps it is just some stupid mistalkes i’ve made
it will be great if i could get some explanations for newbies like me!: )
thanks a lot ; )

well…

I tried your program out, found it made a few low grumbly noises and then quit on a memory allocation fail.

I’m probably not the guy to diagnose your SC troubles, just a beginner myself. A glance at your code above suggests you might be generating a lot of Synths that aren’t being removed fast enough. That would cause the memory fault. The pitch selection logic seems a bit odd. I tried your code with the sawbass decay a bit shorter, and pitch selection tweaked as follows, and it worked for me:

(
SynthDef(
“sawbass”,
{
|note = 35, amp=1.2, cutoff=350, decay=1|
var env, audio;
env = EnvGen.kr(Env.new([0,1,0],[0.001,0.4],[3,-5]),doneAction:2);
audio = RLPF.ar(Saw.ar(note.midicps,amp),cutoff)*env;
audio = CombC.ar(audio,1,0.125,decay);
Out.ar([0,1],audio);
}
).send(s);
)

(
g = OSCresponderNode(nil, ‘/trigger’,
{ |time, responder, msg|
var pitch, triggerIndex = msg[1];
var scale = [ 40, 41, 43, 45, 47, 48, 50 ];
var note = scale[ triggerIndex % 7 ];
Synth(“sawbass”, [ note, note, amp, 1.5] );
}
).add(s);
)
