Add a MIDI Sync settings card (before the binding cards) with Send and Receive MIDI clock toggles, both off by default and persisted. Send: a dedicated thread emits clock (0xF8) at 24 PPQN plus Start/Stop on the transport edges to every attached MIDI device (USB + Bluetooth), and — because a sequencer should drive gear, not just its tempo — also forwards the tracks' note-on/off on each cell's MIDI channel. Notes are queued from the audio thread through a lock-free ring and drained by the send thread, mirroring the mono-per- track cell lifecycle; stop/pause/panic release everything so external notes never hang. (Per-channel Arpeggiator/Transposer are internal FX and aren't reflected.) Receive: MidiInput now forwards real-time bytes to the clock module, which follows an external clock — Start/Continue starts the transport, Stop pauses it, and the pulse rate drives the tempo (a tempo + transport follow, not a sample-locked slave).
