Is it possible to turn off an EQ channel?
At the moment the EQ operates in a glorified graphic eq mode. If the number of operating eq channels was variable it would be a fair bit more flexible. With only 3 channels; low, mid and high; you can get a nice even curve "smilie face". Currently the eq needs a fair bit of tweaking so the bands dont interfere with eachother.

As EQ is parametric, you can do whatever you want . To make it 3-channel, define centroid frequency for all other channels as, say 20kHz or near it, gain 0, Q 0 (that is, out of audible range, no gain, infinitely narrow, in effect switching them off). Then define the remaining three channel's parameters as you wish; don't forget to widen them, though. (I admit I never tried this - I still keep frequencies as predefined and Qs in automatic mode.)

Perhaps 4x5 channel mode is close enough to your idea.

Finally, I seem to remember that a simple bass/treble control for EQ challenged accessible through the knob was planed.
