Diki: Though I agree with you about this for a true live BAND situation, in a 'one man band' keyboard situation, where the audience clearly sees there's NO drummer or drumkit on stage, but merely a keyboard + someone sitting/standing behind it, I'd still recommend pulling the drums back just a tad and bringing up the live played keyboard parts. Afterall, it's the keyboardist/singer the audience (paid) came to hear.
