Diki and Dennis (miden),
Why do you think the keybed is the same as the one on BK-5? In the video the keys appear longer and differently shaped. Also, the video teases that there will be some kind of on-board Vocal Harmony. Something Fran reported at roland-arranger.com suggests that there will be provisions for score display. From the BK-7m you have to figure on FC-7 input, as well as the ability to turn on & off UP1 and UP2 voices, Manual Bass. Plus the mastering tools from BK series that were never present on G-70. The BK-5 has a fully-featured rhythm composer (on-board style creation) and Makeup Tools. The menu parameters are pretty deep. What's left from the G-70 that this lacks?
