OK, I've finally got my Z8, and am loving it so far

I spent the day making my .tks file for use with 3.2, only to find (once I actually started playing a set) that I was getting the nasty squeaking after a bit in vista. GrrRRRRrrrr!
So I decided to give TPro a try, only to run into the same rotary problems that people have been describing in this thread - the rotaries work when turned one way, but not the other. I have a feeling this is more to do with TPro than the Z8 though, as when using the rotaries under T3, they worked perfectly. I've sent a message to the TPro beta list to see what I can turn up for you guys.
Incidentally, I've not noticed any hiss on this unit, however, from the sounds of it, it looks like Korg's "solution" was to install a gate circuit in the mixer - when making a noise from silent (eg_. starting your first track ), there's a slight delay while the gate disarms itself, before the sound kicks in, which is quite annoying. Can anyone with a newer model (ie. no hiss) Z8 confirm this?
