the MPC doesn't slave to MTC as far as i know. it can use MIDI Clock
and/or MIDI Song Position Pointer. Ardour doesn't generate or response
to either of these message types (yet). This is because of its root in a
studio environment rather than a music-production environment - the
class of devices i was interested in sync-ing with handle MTC better or
instead of these other types of signals (and note, they are not a
replacement for MTC, or vice versa)

its likely that if you ask ardour to send MMC, it will send Record-
Enable message with the "ID" field set to "all". not sure what cubase
does. maybe it doesn't bother to send RecordEnable at all, for this very
reason. the behaviour should be configurable, i suppose.

the trace control whether or not ardour prints a text trace of all MIDI
i/o to its standard error output. nothing more or less.
