Nothing currently will grab a chord sequence live, on the fly. They all need setting up in advance. We are currently discussing ways to do this. Only way to get it 'live' is to buy an older G1000 and earlier) Roland arranger.

I have heard from one of Roland's top European demonstrators that STILL (or at least, last time I heard from him) uses a G1000 in preference to a newer G70 (for his own, private gigs), then he MIDI's it to a TD drum module, VK organ and Fantom rack to get basically the G70 'sound', but you can still use the Chord Sequencer.

Roland need BADLY to revive this feature... at least they would have ONE feature that they could claim absolutely no-one else has (OK, there's quite a few, but this one relates to live play! ) that is as revolutionary as SA and Mega guitars.
