Roland's TB-303 (1981) was built to stand in for a bass player and flopped. In Chicago, Phuture couldn't program a cheap one, so DJ Pierre twisted its cutoff and resonance as it played: the squelch of “Acid Tracks” and acid house.
Built to fake a bass. Twisted into acid.
Facts
- Roland launched the TB-303 Bass Line at the end of 1981 (US price $395). Roland says the plan was to recreate an electric bass guitar for solo performers, synced to its TR-606 drum machine as a portable “backing band”.
- It didn't really sound like a bass guitar, and it was hard to program: you entered every pitch first, then the timing, then accents and slides. It flopped. Roland says about 10,000 were made (Sound On Sound once reported a rumour of nearly 20,000).
- Second-hand 303s went cheap. DJ Pierre remembers Spanky paying about $40 for Phuture's (Spanky has recalled $200), and it came with Japanese instructions. Around 1985 in Chicago, still working out how to program it, Pierre twisted its cutoff and resonance while a pattern played. That jam became “Acid Tracks”.
- Ron Hardy's first play of the tape at the Music Box emptied the dancefloor; after three more plays that night the crowd was won over. Marshall Jefferson had Phuture slow it from about 128 to 120 BPM, and Trax released it in 1987. In 1988 acid house exploded in Britain.
- On a 303, an accent raises the filter cutoff as well as the volume (quick repeated accents push it higher still), and a slide ties one note into the next. Roland's TB-03 (2017) keeps the original Pitch and Time write modes.
- The flop is now a collector's item: by 2017 an original fetched over £2,000 second-hand (MusicRadar).

Script
This squelch was supposed to be a bass guitar. Roland's TB-303, 1981: a bass player in a box for solo musicians. It didn't sound like one. It flopped: about 10,000 made. Programming it was a puzzle: pitches first, then timing. Around 1985, Chicago's Phuture got one cheap and couldn't crack it. So DJ Pierre twisted the cutoff and resonance while it played. Same notes. Only the knobs moved. Accents kick the filter open. Slides glue notes together. Out in 1987 as “Acid Tracks”. A year later, acid house swept Britain. Built to fake a bass. Twisted into acid.
