Thanks - not sure I understand your message. To EQ the stereo channels - but that won't improve it..?
..you're right about presets... except the piano/grand, which I did apply more ADSR techniques to - perhaps not enough(?) I'll take a look at a "master" reverb effect and tinker about with it.
I haven't taken a real close look at the ranges, so I will try that also.
Thanks so much - learning, learning, learning...
