Jan,
I tried adding a Midi track w/ Micrologue assigned (using IAA). That plays perfectly in tune.
I left the track and added a 2nd MIDI track using the internal piano sound. When the pitch bend range is wide (approaching 12), I’m still getting “stuck” detuning, but not as bad as before. Strange… Will try some more and send you the file.
Also, I should probably ask this in another thread, but, please, please, please, add an acoustic bass (i.e., jazz bass) sound to the built in collection. 
It is sorely needed. As is, I have to waste resources using IAA to SampleTank, etc. every time I want to use an acoustic bass sound in a project.
Thanks,
Dan
