Vertical stem controlProject BPM + key syncEvery move enters ReplayMove through a set without losing context. Prepare music, perform it, then open the exact performance in Replay.

Bounded audio historyConnect MIDI, guitar, microphone and line inputs. Load software instruments and print safety lanes.
Live inputs + MIDI mappingEvery fader, cue, effect and transport gesture returns on the same clock beside clean and printed audio.
Sample-identical intent replayAdd whole folders, preview audio, analyze BPM and key, then arrange by compatibility or readiness.

Four instant scene slotsPackage state, sources, manifests, diagnostics and captures so the set can move safely between Macs.
Export Center preflightMaster, channel and stem routing use the same clear target model. The rack always tells you where the next effect will land.
