The new Roland gear is up on their site...
VG-99 Guitar System This looks like the mother of all guitar modellers - like the old VG-8, it runs from a hex pickup, has a tonne of guitar and amp models, and a MIDI out port. I'm not sure how you use the ribbon controller while playing guitar, but, you know, it's cool to have.
MV-8800 'Production Studio' Their big daddy MPC4000 killer, with built-in TR808/909 Space Echo models, a colour screen and an output for a monitor, it's almost like... using a PC.
V-Synth GT A colour screen, a few more knobs, and a completely baffling parade of made up buzzwords - "revolutionary Articulative Phrase Synthesis technology"?
