When I search for how to do voice stealing in Pure Data, I find poly. But poly just seems to be for MIDI notes. I'm calculating frequencies on the fly; MIDI notes won't work for me. How do you do voice stealing in Pure Data when you aren't using MIDI notes? Thanks for any help or suggestions!

@jamcultur There was recently an interesting thread on voice stealing which should help.
Although the op was looking to sort data as lists tagged by symbols you should find the discussion useful, and @jameslo wrote some pseudo code to break down the problem... and a patch to solve the problem in Pd.

Thanks, I'll take a look at that.
