Hi Volovicg,
Thank you for your detailed reply!
Most of the instruments are on a specific midi channel as I am using Kontakt multis for each instrument.
I have noticed the following since my last post:
The score window DOES play back the CORRECT instrument when the score window is ONLY displaying that individual region.
The score window, when displaying multiple regions, is playing back the SAME wrong instrument. For example on my current score when displaying all regions, and no matter which track I have selected/am playing in the arrange page, it is still only playing back the SAME string patch in Kontakt, no matter which region I am playing eg. bass, flute, etc.
Here are some screenshots and also a screen video explaining the issue.
