I have a score set up with horns, guitar, bass, drums. No matter what I do, when I press keys on my MIDI controller I hear drums. Now the score itself plays back fine. Each track is properly outputting. What am I missing? I have gone through every possible MIDI setup option and I don't see where this behavior is coming from. I don't see anything that is making drums default playback channel for keyboard input.

Thoughts?

thanks
