Bc2000 (for the BCF2000 & BCR2000)

Hi,

I'm trying to set up a preset on my BCF2000 to use the faders to
control the volumes of the MIDI channels 1-8 on any multitimbral synth.

Sliders 1-8 are set to control CC7 (volume) for each of MIDI channels
1-8. So far so good. But when I tried it, moving any of the sliders
changed the volume of ALL the channels simultaneously.

Any ideas where I might be going wrong?

Cheers
Andy
