I've read several related posts to my issue, but I'm still somewhat fuzzy as regards the actual solution. I am using GPO4 as a VST plugin in Cakewalk Music Creator 5. On some instruments, after I play through the piece once, the volume will reset to zero. This happens after playback stops. I have noticed that the ModWhl is resetting when this occurs. What do I do to stop this from happening?
Thanks, German! You sent me down the right path. It took me a minute to find, but on Cakewalk MC5 the setting you referred to is located in Options\Project\Midi Out - Zero Controller When Play Stops. It worked!
