Re: [sc-users] |i|

If you want the Mix.fill to return a stereo signal for instance, each iteration of function needs to return an array of two items. If you need a four channel output, each iteration has to return an array of four items.

That's what Mix.fill does. It sums the results of the Function.

Thanks for responding,

but why  SinOsc.ar(arrayfreq[i]);  sum the array in one channel and without it becomes a multichannel?

|i| is a shorthand for arg i;

Mix.fill passes an incrementer into its function, here you are giving that argument the name i... it will start at zero, and increate to arrayfreq.size-1

Best,

Hello List!

What does |i| means in this context?

Mix.fill(arrayfreq.size, {|i| SinOsc.ar(arrayfreq[i], arrayphase[i])});

I undestand that it´s a Argument, and empirically I found that without it becomes multichannel (generally I would solve it with a ".sum")

But I havent found in the help a explanation why or what is it.

Thanks
