Well a few things I've noticed in particular.
There is one key that sounds like loud plastic on plastic every time
it is struck. The sound comes throug the output normally though so I
am not too worried. Maybe the padding came loose under the key??

From what I saw in the manual, you cannot control every parameter on
the Z1 with MIDI CC#'s. Only the ones that have designated controls
already. Is this true? It would have been nice to hook my MIDI
knob-box up to the Z1 and have it controlling all of the parameters
that do not have controls. Did I miss something or is this true?

I can't figure out what all of the rumours about this being a hard
synth to program were all about. I find programming this beast
similar to cutting through butter.

I am not so hot on assigning the knobs though but I am sure I will get
used to it once I really dig in to the manual and have some time for
it all to fully settle in.

I can't believe I ever lived without this synth!
Best purchase ever except maybe my V-synth. But at a fraction of the
cost of the V-synth, I'm thinking the value for $$ is #1.
