This happens again and again and I can't figure out what's going on.
I'll be trying to compose a part, perhaps I'm improvising on my midi input keyboard. The sound will be whatever the sound that I was last editing in Finale. I'm playing on the keyboard...and suddenly the volume of that instrument drops precipitously. Like it'll be 50% of the volume it was. And then...nothing seems to bring it back up to normal.
It seems like something has reset the midi volume of that channel. But how can I bring it back to normal? It doesn't seem to be a function of the mixer, nor of dynamics in the score. The only way I've figured out how to fix it is to change the instrument patch completely (if it was a flute, make it a harp for a minute). then the volume will be back to normal and I can bring the flute patch back and it'll be back to normal.
So the big questions are:
a. what might be happening?
b. what's the right way to fix it?
it seemed like in the old days it was pretty clear what the midi volume was for each channel, it was in the instrument list. Now...I don't know where that's gone. It doesn't seem to work the same way as the mixing board.
For playback, I'm using Garritan Instruments selected through the Score Manager.
Midi controller keyboard is an old Casio FZ-1.
Midi interface is Focusrite Scarlett 616.
