Hello, I've created a score in Finale. It's Ok. I've put up GPO. It plays the score ok, But... the instruments are out of balance? What to do? (The cellos are hardly audible, but violas are...etc.)
Each instrument in the player has a volume knob and can be adjusted manually. Or: Go to the Options menu of the player and activate "cc7 and cc10." This will allow you to send MIDI volume data (cc7) to set the levels of each instrument.
Sounds much better now.
