Re: Velocity with fvcurve

Thank you for the reply!

Changing the volume channel (7) did indeed change the the resulting volume
when exporting to a file.  Unfortunately when I hooked it back up to the
Yamaha piano, the volume did not change,  This piano is fairly old, its a
Disklavier Grand Piano from circa 1990 and I'm guessing may not conform to
completely to midi standards.    I am going to keep poking at it to see
what the magic combination is, I know others have managed to adjust the
volume with commercial solutions.  One thing i was reading up on was
sending a sysex MIDI Master Volume message, i have no idea if this will
have any effect, but we will see.
