Re: [sc-users] Re: all audio explodes when trying to trig record clean feed via groups

Hey James,

One last question: As you can tell I am already in this bad habit with Out.ar and multichannel expansion. I understand your point with the example you provided (thanks btw) but am confused about what the correct way to make that mono signal stereo would be. Is this the proper way to do what I was trying to do (below)?

version 1 (condense two signals to mono, expand to stereo)

m = { arg cleanAmp = 0.5, loopedAmp = 0.5; var clean, looped, sig; clean = In.ar(~cleanBus.index, 1) * cleanAmp; looped = In.ar(~loopedBus.index, 1) * loopedAmp; sig = clean + looped; Out.ar(0, sig!2); }.play(target: ~finalMix);

or version 2 (clean in channel 0 looped in channel 1)

m = { arg cleanAmp = 0.5, loopedAmp = 0.5;

    var clean, looped, sig;

    clean =  In.ar(~cleanBus.index, 1) * cleanAmp;

    looped = In.ar(~loopedBus.index, 1) * loopedAmp;

sig = clean + looped;

Out.ar(0, [clean, looped]);

}.play(target: ~finalMix);

Glad to hear it's working better.

UGens shouldn't be asking for a "buffer.index" -- a Buffer object knows how
to report its bufnum, not an index.

You need to change this to Out.ar(0, sig) -- DO NOT DO [0, 1] here.

Try this to see why:

s.boot;

s.scope(3);

a = { Out.ar([0, 1], [SinOsc.ar(880, 0, 0.1), Saw.ar(440, 0.1)]) }.play;

amp = 0.1 to save your ears. You can use the right-hand slider to scale the
display up.

Bus 0 = sine. OK.
Bus 1 = sine + saw. Nope.
Bus 2 = saw (+ hardware input, if you have the default two hardware output
channels)

I'm quite sure this is not what you wanted.

As I had said before, if you find yourself getting in the habit of writing
"Out.ar([0, 1]...)," better to get out of that habit right now. It's not
correct usage.
