No MIDI on the Korg Mono/Poly? Here's how to bridge it
Free tool — see exactly what kind of converter connects it to a modern MIDI setup.
Strengths
- 4 stackable VCOs can be played as one huge unison mono voice or spread across 4 paraphonic notes
- Built-in step sequencer and arpeggiator add composition tools beyond a plain synth panel
- Distinctively thick, aggressive analog tone well-suited to basslines and leads
Trade-offs
- Paraphonic (shared filter/envelope) design means it doesn't behave like true independent polyphony
- No MIDI on the original, requiring a retrofit or CV interface
