- mix: independent strips process in parallel (rayon, native), parameter pushes cached, plugin sync/routing order cached per session structure; plugin and render benchmarks - UI: Playback Engine, I/O Setup (bus rename/delete), Keyboard Shortcuts windows; clip gain line + info; folder open/close; tempo changes from the ruler; Inserts/Sends F-J, EQ curve and comments sections in the Mix window - docs: control protocol and MCP guides Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
