Digitakt audio tracks via O.B. have not same latency with midi tracks controlling AU-Plugins in Logic-X

Hi guys.
There is anyone here who get correctly in time together in multi track mode all the D.T. audio tracks via O.B. and all midi tracks controlling AU-Plugins in Logic-X???
In my case I get the playback of the midi tracks about one step before the audio tracks.
I already adjust buffer size and recorder delay while triggering a Trilian AU-plugin, but no deference.
Τhe audio tracks are correctly in time, the strange thing is that the midi tracks start to trig the Trilian (…or any AU-Plugin) about a half of a step before the audio tracks.
I hope Elektron developer team will resolve this issue in future upgrades of O.B.
But until then…
Is there any Logic user who found some nice tip???
