I think there's a slight penalty but it's not enough to worry about in most systems. Anyway, when you don't have any choice, best thing is to just do it :)

Hi there, recently, I had to use the adat outputs of my audio card in Pd, but these channesl are from 16 to 24 (they skip all the analog outs plus some other things like SPDIF). My question is, if I ask Pd to work with that much audio outputs (24 of them), but only use a couple of outputs (like [dac~ 17 20] for example), is it more expensive on the CPU compared to if I only have 2 outputs and use [dac~ 1 2]?

In short, does the cost depend only in the number of outputs in a [dac~] object?

Moreover, does the number of [dac~] objects make a difference? For instance, having one [dac~] with many outputs costs the same as different [dac~] objects for each output?

I always had the idea that too many outputs could really mean a lot more cpu cost, but I'm not sure now if that cost is really real or relevant. what do you say?

thanks
