By the way. While owning the kenton pro-solo I made a complete
"sysex-integrated" midi-device panel for cubase SX3. Works like a VST
plug-in with the automatation functions "R" & "W" (read-write). As I became
almost an expert in constructing these things, I used my skills to help a
friend to control his Kenton pro2000. Both of these could be uploaded if you
just tell me you´re interested. Similar devices could of course be
programmed for the doepfer midi-devices that respond to sysex.
I have also succeded with a complete AKAI-S6000 panel, with a
32-parts/channel mixer, loaded with real-time ctrls. I´ll gladly share this
one to if anyone around is an owner of S-5k/6k samplers.

There is a guy I found in the internet, that seems to be the real
professional on midi-device panels for cubase, as he offers a big collection
of these at his personal website: www.cykong.com Impressive stuff! Possibly
some of your studio-gear is in there...Check it out!
