The 303 lives between the sheets. Spreadsheets Synth is an acid bass synthesizer with a built-in step sequencer — a cultural product of the band Spreadsheets, tuned to 313K and pointed straight at the dance floor. THE SQUELCH Sawtooth or square through a resonant filter with cutoff, resonance, decay, and accent — from rubbery basslines to screaming acid leads. Add distortion for grit, then send it into orbit with the phaser and delay. THE SEQUENCER Program patterns step by step, set the line looping, and ride the cutoff live. It's an instrument for performing, not just programming.
