This is kinda frustratin'

I'm trying to use one of these beasts with my sequencer.

All 4 of these models apparently operate the same.
So if you've got one of those, and know why they
don't respond to a midi control #7 (channel volume control)

well, I'd appreciate knowing how you made channel volume work for ya.

For me, the drums on channel 10 DON'T seem to respond to
channel volume control (control #7).
They're always THUNDEROUS compared to the piano channel...

Anybody got any help for me?

Thanks much,
...Steve - writing my own piano practice program ...yeah, I'm crazy like that
