Bc2000 (for the BCF2000 & BCR2000)

Hi everybody, 

is the BCR2000 better for live-tweaking of the Volume/EQ parameters?

Maybe the tutorial items at youtube.com make it look more complex than it is.  And now i have a BCF2000 box still unopened..  

SHOULD I GET THE BCR2000 INSTEAD?

i would like to make a simple live mix from two CD's  with just 4 tracks/channels, and apply some parametric EQ, and echo.  During a playback of the  song, i would like to push some modifications onto it by tweaking some of the midi levels (such as volume, L/R panning, echo).

it sounds like the motor-faders on the BCF will resist being modified during playback.
Does that mean each take is starting from scratch?

I am stuck right now although I anticipate being a fast learner

Thanks
