Re: [sc-users] Deal with In and Out with crucial Instr and Patch

thanks.
If i do

(
Instr(\reverb,{arg inbus=2, mix=0.5, room=0.5, damp=4, vol=0.3, outbus=2;

    var out, in;
in = In.ar(inbus+16, 1);//Input channels offset is +16 so to get the second input add 16.
out = FreeVerb.ar(in, mix, room, damp, vol);
Out.ar(outbus, out);
});
)

p = Patch(\reverb,[2, 0.5, 0.5, 4, 0.3, 2]);
p.play(bus: 2);

I have

^^ The preceding error dump is for ERROR: source has nil rate Patch("reverb")

Could it be someting about Specs defaults?

// allocate a bus at index 10, 2 channels
b = Bus(\audio, 10, 2);

p = Patch(\reverb, [2, 0.5, 0.5, 4, 0.3, 2]);
// play patch onto that bus
p.play(bus: b);

I think you can also just pass in a number for what bus to use:

p.play(bus: 10);


You can also use In.ar and Out.ar within the Instr if you want.

Thanks mauritohm.
For example i don't understand why this

Instr(\reverb,{arg inbus=2,mix=0.5,room=0.5,damp=4,vol=0.3, outbus=2;

    var out, in;
in = In.ar(inbus + 16, 2);//Input channels offset is +16 so to get the second input add 16.
out = FreeVerb.ar(in, mix, room, damp, vol);
Out.ar(outbus, out);
});


)
p = Patch(\reverb, [2, 0.5, 0.5, 4, 0.3, 2]);
p.play;

gives me the following error when i evaluate p.play;

If I recall correctly, you can just Out.ar(4, signal) and then you will be sending your output through the fifth channel (our bus).
Remember to set SC outputs using serverOptions.numOutputBusChannels, then in Jack just route SC's out 5th channel to whatever input on the other side.

I hope it helps.
Cheers

Hi eddi,
thanks for your suggestions. 
I'll do further explorations.

Hi Alfonso,

I have little experience with the Instr/Patch way, but recall that it works well with James' MixerChannel quark, which I rely heavily on (thanks, James!)

Using it might solve your challenge already. If not, you can at least peek at how he does it.

Cheers,
eddi
