Keep vocal pocket clear in verse sections.
Let hook sections lift with stronger kick + 808 movement.
Use imported one-shots when loaded; synth voices stay as fallback.
JSON export remains the source-of-truth handoff format.

Phase 7.3 TimGM6mb Reference Kit

MIDI playback parity

This build keeps MIDI export untouched and routes web playback through a bundled TimGM6mb-rendered GM reference kit first, so the page follows the same note, velocity, and timing contract as the MIDI file.

Target Track

Bundled reference samples play by default. Local samples still override a lane for this browser session. For exact external MIDI-player matching, replace assets/reference-kit samples with renders from the same soundfont/player.
