Been wanting this for a while now (thanks Doug Wimbish and Steve Stevens). Now I've finally got one:
I've just spent 20 minutes messing with the original banks and some cool fun moments. Not only does it have some standard tap controllable tremolo, but it's got a cool momentary switch feature so I can turn on slice patterns without being too much of a keyboard player. Plenty of experimenting times ahead.
Congrats, are you going to upload clips?
