Hello again - Sorry for the delay.
LandonPd, I tried the patch with the array and the sound breaks up far below the the -1 to 1 limits. If I record the loudest 'clean' signal out to a program like audacity, it's definitely reflected as a weak signal. If I amplify the audio in audacity to fit the -1 to 1 limits the same crackling distortion emerges.
Gilberto, I wasn't able to fix the issue with the limiter. It does the job initially, but if I compensate afterwards to get a sufficient gain level, the distortion comes right back.
I think you might be right about the 'algorithm', but I'm confused about this since the patch seems to be basic additive synthesis with osc~s.
Here is one more patch with a simple two-note chord. I get distortion at *~6 with a weak signal in the array window.
The high *~ values I believe are just balancing out the low *~ values at the output in each voice-abstraction.
At some point I'll try sampled sine waves and see if that helps
