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.
