Build a Polyphonic Synth

A polyphonic patch must keep several notes alive at the same time. That changes the job of the voice modules: each active note needs its own evolving state rather than sharing one mono envelope and one pitch.

Build it

Use the polyphonic oscillator, filter, envelope and VCA family with a performance source. Establish clean note-on/note-off behaviour before adding effects or elaborate modulation.

What to listen for

Hold a chord and release notes at different moments. Each voice should behave as part of the polyphonic instrument. Then add velocity or another performance source to make repeated chords less static.
