I started tinkering after I read your message, and I created a little gadget that traces mouse motions and recognizes fairly general conducting patterns. One can extract timing and intensity information for the purpose of generating MIDI clock events as well as MIDI controller values. I'm tentatively calling it Boa Conductor. I've got a few questions: 1. Is anyone interested in a tool like Boa Conductor? What I've done so far was just for kicks; I now have to decide how much time and effort to put into polishing it. 2. Are there any MIDI sequencers/players for Linux that can be driven by external clock messages? My understanding is that Rosegarden does not currently work as a slave but that may change in the future. MusE can work as a slave, but I never used it before (has anyone tried driving MusE with clock messages?). I don't think timidity expects to be driven by a MIDI clock. How about other MIDI players? 3. Would it make sense to have a feature that uses JACK Transport rather than MIDI clock? Best, Peter
