Trouble with using an open keyboard or module with an arranger is that many of them lack much flexibility in the MIDI routing and header setup info...
I am seriously considering a V-Machine when the Core Duo version drops, but I am lucky in that my G70's Part routing and MIDI send filters are quite extensive.
The better these things get, the more important it is going to be for arranger users to scream loudly about how bad most of their MIDI flexibility has gotten in the last few years...
Oh, and Bernie, I completely agree. I don't say there is NEVER a good use for an open keyboard live... just that the vast majority of arranger users need good live flexibility (or we would already be using WS's

). If you have the luxury of knowing in advance EXACTLY what you are going to need 100% of the time, an open keyboard might be just the thing.
But there's a REASON we are all here on an arranger forum... most of us have already figured out that what we need in a live keyboard is an arranger. Not a WS, not an open keyboard. No doubt there's a forum for people that have worked out that what THEY need in a keyboard is what an open keyboard provides. But so far, IMO, the open keyboard has yet to produce a mature arranger. Still in its' infancy, I regret...
