I've uploaded the 100th OWL Patch - it's a pretty primitive, 5 voice (but not polyphonic) drum machine made in Pure Data, with kick, snare, two toms, and hi hats.
It's more suited to the OWL Modular. The button triggers a drum sound, knob a selects drum sound, knob b selects the sound you're editing and knobs c and d edit that sound.
I'll be working on making it sound better and ironing out some bugs regarding parameter changes.
Here's the patch:
Hope you enjoy, please feel free to share any tips on improving sound (I was more focused on getting it working than sounding good!)
