Caustic Song file (optional):
Here's something I was messing around with. I used 5 ModSynths. The first one just has patterns of notes, and 4 Machine Input modules that send the notes out to the other 4 ModSynths. Each of the other 4 ModSynths are set up pretty much the same (Oscillators, Filters, LFO, etc.) but each has different Arpeggiator settings, and two of them have automated Insert FX.
So a single 4 or 5 note pattern in the first ModSynth is generating a bunch of intertwining parts that all fit with each because they're using the same notes - just with different Arpeggiator rates/sequences and synth settings.
This probably isn't anything new, but I wanted to give it a try. Caustic continues to amaze me!
