Roland:

GO back to basics, a Pro arranger's draw is it's styles.....not a re-cicle of them, and most of all, make them user-playable, lately all I hear in the G70 is a FEW new styles, there is a small section that is aceptable, but that is it, I would never buy ANY arranger for only 15-30 New styles.....forget about the VA's styles carry over, I got rid of my VA faster than ANY keyboard I ever owned (that was when it came out), I had it for around 4 months, and God know;s I really tried, I am a Pro keyboard player, also a keyboard specialist in most brands like Ketron, Yamaha, Korg, and I owned several Roland boards.
Also it should be a demo using ONLY styles, and another if you wish, using custom SMF's showing the tone generation, but making it clear what is been use in that particular demo, like the demos from Ketron, using a style. I agree with Craig_UK.
