Not much that I have on Windows or Linux support clock messages. MagicBaton was a MIDI-player that added events based on the mouse-conducting. Alternatives: 1. Run the Boa in Parallel with whatever sequencer or player is going through jack or such. Boa would then put out simply omni/overall level and tempo events. 2. Run Boa as a plug-in Rosegarten, Muse or other such program. In this case, it would work on one track/channel and insert expression (and tempos) or in an omni mode as above. For rehearsing (MagitBaton's parlance) one track, one would probably want to disable tempo changes and conduct expression. Omin/overall would do level and tempo. 3. Controlling another software via midi-clock and some volume control device. This assume, naturally, that this software is available :-)
