Remaking the bass synth from the 1996 song "Everybody Needs a 303" by Fatboy Slim can be an exciting challenge for any synthesizer enthusiast. Here’s how you can create the "Everybody Needs a 303" bass patch and play this iconic sound on most hardware or software subtractive synthesizers (Serum, Vital, Pigments, Prophet, Korg, Moog, etc). We've included the preset download directly for your convenience, but we strongly recommend you use our programming tutorial to recreate it yourself.
Original Audio
Fatboy Slim’s 1996 debut single “Everybody Needs a 303” features a prominent bassline that is quintessentially Roland TB-303. The sound, which starts at 2:30 in the track, is characterized by its squelchy, chirpy quality, typical of the TB-303.

Getting Started
- Start by initializing your synthesizer to a plain saw with no filter, modulation or effects. For soft synths use the "init"/"default" preset or the the button to reset all parameters to their default factory values.
- No two synths are exactly alike, so treat the values below as approximate, and use your ear.
- Percentage values (e.g. 50%) represent the relative position of a knob or slider within its full range. The full range of each parameter may differ from synth to synth, so use your ear.
