The TB-303 Acid Bassline Explained in 75 Seconds

That squelching, screaming line running through acid house, acid techno and a thousand warehouse raves started life as a failed bass-guitar machine. Roland’s TB-303 flopped in the shops, then Chicago producers twisted its filter into something nobody had heard before. In just over a minute, Cableguys strips the sound down to its parts: one saw or square oscillator, a monophonic voice, a 16th-note pattern with overlapping notes for those gliding slides, a resonant low-pass filter driven by an envelope, and distortion to make it bite. Why it is worth your time: you do not need the original hardware or an expensive clone, because the whole recipe is rebuilt in the free Vital synth. Watch it once, then load Vital, copy the settings, and spend ten minutes riding the cutoff and resonance by hand while the loop runs. Record those moves, because the constant tweaking is what turns a simple pattern into proper acid.
