Well, Nick, it looks like you have shot me down...!
Despite many pleas for it over several years, Roland still insist on only allowing one 'drum track' in the style section, a track that does NOT transpose as you change chords.
You CAN do it to the SMF sequencer, which makes the omission in the style section even MORE annoying
Oh, well.... Back to the drawing board.
Fran, do you actually PLAY the guitar mode 'live'? I find it to be a reasonably useful tool for making an SMF (which I understand the vast majority of your show is based around), but until it is integrated with the Style section (and THAT is going to take Roland coming up with a non-transposing track, as well!) it is little more than a gimmick for arranger use.
And, as much as I love my G70, I have yet to hear ANYTHING in it's soundset that comes even close to Yamaha's Mega voice guitars, when programmed correctly. Drums, pianos, organs, synth sounds, the G70 has a definite edge, IMO, over the Yamaha's. But the extra performance abilities of the Mega voices (and the fact that you CAN use them in a style) gives this one area a strong nod to the Yamaha's.
I am not talking about guitar sounds you PLAY (although, even in that area, the SA acoustic guitars sound better, IMO), but style guitar accompaniment... Fortunately, I play with a real guitarist, so most of the time, this is not an important consideration, but this winter I intend to play a few more solo gigs, and am going to miss him a LOT when faced with the G70's average acoustic and electric guitar patterns.
Fran, for someone that uses several different arrangers, including the MS, you seem a strange choice of member to advise me to not use anything else and stick solely to my G70...!
