Unforturnately not optiomal because MIDI is in fact very flaky
timing-wise, being a serial protocol. So even if MIDI events are
quantized in the sequencer they can never be sent at the same time
through a MIDI port.

No, just use what gives enough "pre-timing".

Seems you have been missing the basic point in all this, which is that
the EDP has to run synchronized to the MIDI sequencer. I've heard
people doing that well with MIDI Clock and myself I have been doing it
a couple of time with beat pulse sync (recorded a pulse from the EDP
into Logic and then playing back that pulse into the EDP to make it
follow).
