I am using GPO Studio v 1.2 with the bundled Overture SE patched up to v 3.6.1. The problem is that when ever I add any new notes to my score and play them back through GPO, the volume level of the passage I just created goes very low and comes back up the minute it gets back to a passage that was not modified. This just started happening recently. I tried recreating the GPO studio instruments from scratch instead of using my saved .gpo file and it still doesn't resolve the problem. So I am guessing that the problem lies with Overture. Does anybody have any suggestions? Thanks for all!
