that's right, the tempo is in beats per minute.

Are you talking about "beats_per_measure" in the source code? That
stuff is the numerator of the current time signature during
performance mode; AFAIK it's used only by the metronome.

currently that can't work because the filter is applied when the
track is recorded and not when it is played. In such situations I
simply change the channel configuration to match the channel the
track is using.

But there should be a way to remap events in a track, that's on my
todo list.

trackinfo output contains the track length, but this isn't very
readable. To bank a track to the end you can use 'trackcut'
function and give ~0 (or any large number) as length argument. For
instance:

trackcut 0 ~0 0

sysex messages aren't pocessed as ordinary midi events; they're
never passed from the input to the output. If there is a "current
sysex bank" defined, in record mode sysex messages are appended to
it. So, to stop processing sysex messages just define the current
sysex bank to 'nil'. I plan to add filter rules for sysex messages.
