David,
So how would Raton-Conductor work? Again, not as
simple as it sounds.
Minimally, one would move the mouse in a ecliptic (or circular) motion (as
suggested by MagicBaton's instructions for beginners). The size of the
vertical diameter (or average diameter) would be the volume/expression and
tempo or time-codes set by the change in vertical direction from down to up.
Real conducting patterns are more complex but these two principals would more
or less remain.
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
