Howdy.

I have a very simple mixer in my app that mixes two signals at a time and takes the sum and mixes with another signal and then once again for a fourth signal.

This approach worked well before for just two signals but now with four signals to combine it seems like there are some audio quality issues when some of the voices are nil.

I'm no pd expert and I'm stumped on how to do this better.

should I toss this approach or is there a way to preserve audio fidelity when either or both of Voice 2 and Voice 3 have no signal.

It looks like I need a moses~ to conditionally bypass a mixing stage but I have no idea how to pull this off. If anyone can point me to an example that would be awesome.

I can only use vanilla objects.

Thanks!

Maybe something like this?

the reason the number atom in powerpan isn't right is because I didn't make the jitter_guard zero all the unused voices. Should fix that.

You bet. thanks for posting that it was super helpful

I had forgotten about throw~/catch~ that makes it a whole lot easier.

Looks like I can use threshold~ to trigger a throw when a signal is non-zero.
