saw a generative patch for chords on the internet. I can't figure out how to replicate it for mods because he doesn't show everything. would like to know how to fix this patch so I can get going. would love any info on generative chord and synth stuff so I can start making my own patches.

I am particularly interested in altering the the rythm and bein able to generate chords within a key which is what I was trying to accomplish.
