A lot of great info and insights. I guess I got over excited about the E50. Its nice but compared to what I already have it would be too big of a step down. Someday, maybe soon, I'll really have to downsize and revisit it or something similar. Right now since I'm not doing gigs anymore I mostly just use my FP90 midied to my BK7m, and sometimes I don't even turn the Bk on, just play piano, so nice ! Going from that back to my BK9 the key bed feels so different and the piano sound is really lacking compared to the FP90 but for what it is its still one of the best Arrangers, especially for gigging musicians. Diki's idea of a BK9 module is something I've also thought about but Roland just isn't interested these days.
