Someone said, "no ability to change
resonance after note on, questionable cutoff curves, etc"

What do you mean by this? Do you mean, if I am sequencing a lead, 
and while it's playing/recording, I can't change alter the 
Resonance/Cutoff of a lead to get that cool trance form sound while 
it's recording, and record the changes?
