Apps needed:
STRNG
Mozaic – with the Midi CC Randomizer 2.01 Patch available on Patchstorage

This is a simple AUM patch to generate random presets inside the app STRNG. All 32 settings are already mapped to two instances of Mozaic. Simply set the strength of the randomization to your desired amount inside each instance of Mozaic, then double tap the randomize button inside both Mozaics to Randomize parameters in STRNG. Then just play the keyboard to see what it sounds like. Tweak and save the preset inside STRNG if you like it.
Cheers!
