now about tracks with different speeds (tempo?, tpqn/ppqn?) is a
complete another story: the MIDI file standard just doesn't allow for
different tracks/channels with different speeds whatsoever. where did
you get the idea?
At least some professional, if not all professional sequencers allow to
lock tracks at the current used BPM, then it's possible to give other
tracks different BPM. This isn't just needed for freakish
polyrhythms, it's a must to sync special effect sounds to film by SMPTE
and still to be able to change the BPM for some ambient effect
sounds/music. IIUC this is what's the OP produced and wishes to export
and import. This might not be provided by a single file standard, but
the OP wants to split a file into it's tracks and than import it to a
sequencer that allows to use different tempi.
some smart sequencer might but i repeat and assure you that the SMF
format 0 doesn't.
theoretically SMF format 1 does support polyrythmic sequences as each
MTrk might have each its own arbitrary tempo and time-sig meta-event
sequences.
qtractor does not support polyrythmic sequences though. it isn't that
smart you may say ;)
qtractor does support for SMF format 1 which follows the general
convention of one first MTrk (#0) for placing tempo/time-sig meta-events
and, most importantly, each of the following MTrk #'s do hold single
channel events.
however, iirc. the OP asked for SMF format 0 support though. and that is
not, cannot be conveyor for polyrythmic compositions.
hth.
