Finally I had the chance to listen to the G-70 on a Demo Tour the guys from Roland are doing back here. Unfortunetly the "damn thing" was not completly finish (the final software was not ready yet). Anyhow I had the possibility to quickly ear some of the tones and see some of the features. It sounds GREAT and seems to be very easy to use. The piano and guitars are very impressive. The organ sound is also great -maybe the best organ sound I've ever heard on an arranger, with the harmonic bars really "doing the job" as I expected. As I said not everything was ready but the most important (at least for me) - the sound - already prooved to be excelente and powerfull. Hope to get my hands on a final version very soon.
