Thesys on Logic: not in Sync

[Robo2k]

I want to use multiple instances of Thesys sending different sequences to different MIDI synthesizers via Logic Pro 9.1.7 on a Mac.

When Thesys is selected (by highlighting the track), it is perfectly in sync
when I press play.

As soon as I leave the track, select a different one and press play again, Thesys seems to have a "headstart", starting prematurely (about 200ms or so) before all other intruments start. It never gets in sync, even after a few cycles.

I have had a similar issue with another Synth plugin before, but that was resolved with the latest update, so my guess is that Thesys (and not Logic) is resbonsible for the "headstart".

Does someone happen to know how to resolve this issue?

Also a feature request: the MIDI-out selector is not so easy to manage when running more than one instance of Thesys under Logic, sometimes it switches randomly from one synth to antoher! And: how about MIDI channel selection? Would be really cool!

Are you using the IAC bus feature? Unfortunately the IAC bus has no stable timing. This is why we added the midi file drag and drop feature.
You can drag and drop the Thesys sequence to a Logic Midi track and send Midi
from there.
Unfortunately, until now the AU plugin interface does not allow to send MIDI.
We are working on other workarounds.
