LogicPro synchronization with Cubase on one Mac?

Question

Anyone did it? With IAC driver?
I would like to use CubaseSX only as MIDI sequencer - I do dnot need any sound to come out of Cubase...
My goal is to import a MIDI drum track to Cubase and edit it here within Cubase Drum editor, while audition the sound from Logic.
I had a success with sending MIDI to Logic through one of IAC BUS. In Logic enviroment I routed the cable from the IAC BUS on the Physical input to Audio Instrument object where some Drum sampler plugin like DFHS or BFD is inserted. Easy and fast, MIDI data from MIDI track in Cubase are "travelling" to AU Instrument in Logic fine.
Ofcourse there has to be another IAC BUS MIDI port used for synchronizing the playback of the two DAWs. And this is where I was not that succesfull. I tried MTC, also Midi Clock but I never get smooth playback in sync. The tempo started to drift always after playing back song a while and it sounded like a broken Tape deck :))
I choosed Built in audio as a CubaseSX audio driver while Logic was using my mLan network. Maybe I should try to share my mLan audio/midi network between Logic and Cubase?
Anybody tried to do something like that?

Answer 1

I'm using Logic regularly as slave synchronized with MIDI clock via IAC to other applications as master (also Cubase SX). But in my experience it works perfectly only if both sequencers are set to the same tempo beforehand. So I'm using MIDI clock just for start/stop synchronization.
Btw, you don't need a separate IAC bus for transmitting MIDI clock.
