I wanted to post this in case anyone else has this problem. It occurs when combining Vienna libraries with other libraries, at least on Sonar (now Cakewalk/Bandlab). The problem, which affects both Vienna and Synchron libs, is that they lag behind the other libraries' instruments. I could not figure out a way to solve it, until I posted it on the Cakewalk forum, and the resident DAW Genius, scook, responded. Cakewalk has a way to set the timing of a midi inst. ahead or back by a specified amount. This turned out to be -10 in my case. You do it on the track imspector, which has all kinds of controls on it, pan, velovity etc. I never knew what the timing one was for, but I do now. The best part is, it doesn't affect the notes in staff view, they still display correctly (unlike using the slide function, which messes them up).
I don't know how many folks use Cakewalk/Sonar here, maybe not many, but this could affect other DAWS as well, so maybe it might be applicable. It solves a problem which has plagued me for years. Like most of this stuff, it's so simple, once you know the trick. No more using inferior sounds, now, I can use Vienna's great sounds whenever I want! Wonderful!
