Impulse Cycler is a motion-first transient shaping effect that combines level-independent transient detection with synthetic transient layering. Shape attacks and sustains, layer new synthetic transients, and assign tempo-synced LFO modulation to any control parameter. Although for more than just percussion, it often sounds like putting a drum machine on your machine. Hours of pattern multiplication. Hope it can be fun.
