Remaking the bass synth from the 1987 song "Acid Tracks" by Phuture can be an exciting challenge for any synthesizer enthusiast. Here’s how you can create the "Acid Tracks" 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
Phuture’s 1987 track ‘Acid Tracks’ is a seminal piece in the acid house genre, and its bassline is a defining element of this sound. The super squelchy 303 bass sound, which becomes prominent at 1:27, is characterized by its high resonance and distinctive squelching effect. This sound is produced by the iconic Roland TB-303, a monophonic analog bass synthesizer.

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.
