Put SCRAMBLE. on your drums and 808s
One button rolls a new FX chain: glitch, stutter, tape stop, chops, reverb, delay and vocal tune. There are 43,252,003,274,489,856,000 possible chains, the same count as the positions of a 3x3 cube. Save 10,000 presets a day and 1% of them would take 118 billion years, over 8x the age of the universe.
Not just loops: drum buses, 808s and bass, hats, vocals and the master bus. 3,000+ downloads so far.
