OLD JOINT MODEL · SIX INSTRUMENT GROUPS
Keep the harmony. Grow the orchestra.
The original R/H/B/M Transformer still writes the rhythm, real chords, bass and melody. A separate, deterministic prototype distributes those notes among six groups for comparison.
PROTOTYPE / 原型The six-group mapping is not yet a trained orchestration model. Existing model weights are unchanged. Browser synthesis is a sketch, not final orchestral sound.

Shape the score
Six instrument groupsAuto → On → Off
On permits a group to play; Off excludes it; Auto varies its presence by bar. During continuous play, group and tempo changes affect the next prepared segment. Other settings require a restart.

CONTINUOUS PERFORMANCE
Real chords, continuously
No bars playing
MODEL CHORDS · 2 × 4 BARSThe labels match the H stream, not estimated from notes
This is an orchestration bridge for listening and comparison. It keeps the old model intact while we evaluate whether a learned six-group layer is worth training.
