No MIDI on the Roland TB-303 Bass Line? Here's how to bridge it
Free tool — see exactly what kind of converter connects it to a modern MIDI setup.
Strengths
- Built-in step sequencer with slide/accent created the entire acid-house genre almost by accident
- Distinct squelchy resonant filter sweep is instantly recognizable and still widely emulated
- Small, simple, dedicated bass-line tool that's fast to program once you know it
Trade-offs
- No keyboard at all, since it's a step-sequenced bass module rather than a playable synth
- No MIDI, so syncing to modern DAWs requires a DIN sync/MIDI converter
