Notes

  • Current keyboard handling is Ctrl-based in code paths, including on macOS builds.
  • Some actions depend on the current view, active tool, and selection state.
  • Q/H/G apply to the current selected notes in the piano roll.
  • Audio stretch requires rubberband to be available on PATH; pitch correction uses per-session cached analysis and local undo/redo in its own editor.
  • Group is only enabled when two or more non-group clips of the same type are selected on the same track, and grouped clips must be ungrouped before splitting.
  • Per-clip plugin graphs are audio-only and currently available on supported Unix non-macOS builds.
  • The main editor zoom is geometric rather than linear, so equal slider movement produces equal zoom-ratio changes.
  • Undo/redo in the pitch-correction view only changes local correction history; it is separate from global history.
  • Maolan also ships a maolan-cli binary that can play, pause, stop, send panic, and export the current session.
