Weird problem:

No issues when starting at the beginning or starting at a measure containing bass trombone.

When I start playback at a random measure with no bass trombone before she played her very first notes, also no problem.
When I start playback at a random measure with no bass trombone after she has played in some part before my starting point, I hear a continious lowest C# sounding..
This even happens when I set other instruments to solo (and thus should mute the bone)!

I''m working on a piece for symphony orchestra with finale 25 and I am using SE, keyswitches for SE+ and for patches out of Brass I

Any ideas?

I'm very new to VSL, and I can't figure it out how to read the matrices in the manual and let them work in Finale. For instance, if you want a snap pizzicato in your violin solo (SE1), the dump would be KS F#1 according to the matrix, right? But I do not understand the principle of the Rows (V1, V2, sometimes V3) and how to exactly choose the right KS that sets the articulation as mentioned in Row V2. You get my point?
