One finger plays a dark sounding arpeggio on top of an evolving bass note. I may come back and fill in all the params at some point, but meanwhile you can load the sysex.
The Prophet 12 has a ton of parameters, huh? Hopefully the patch contributor uploaded a system exclusive file. If so, take note that the Prophet 12 sends the program back to the same bank/preset where it came from. Make sure you don’t have something important in that slot before uploading the preset to your synth!
