MIDI generator
Sidecar
MIDI phrase player for generated solo material with deterministic local generation and optional localhost coordinator requests.
Opinion
An experiment I gave up on (in favour of MCP).
Functionality
Sidecar plays validated solo phrases against host BBT transport. It can generate
token-free local phrases or request material from the separate
downspout-ai-coordinator process over localhost.
The plugin never owns API keys and never performs network work from the audio/MIDI callback. Routed MIDI is used as generation context rather than passed through.
Status
Taken to proof-of-concept, and left there.
