Working Backwards I am......
As you know doing some amount of work with User Tracks.

Taking a modified version of the UT 10 min template there is an external midi
created.
Within this midi template are some number of multi-bar chords.
Load Realband with this midi template.
Setup voicing and sounds wanted.
Render the Midi to a wav file.
Listen to the wav file and every chord sounds great.. and smooth.
Even the multi-bar chords. No breaks, bumps or sound changes across
the Bar.
Then complete the UT.
Pick out a BIAB style demo to pak with the UT zip.
Play this demo and across every bar is some kind of change.
Same chord, just a bump as tho the chord is re-played.

I did/do have a similar thread in the UT forum, but minimal responses.
Interesting to read what you folks have said.
