Nobody answer to Roland fan question. It seems there are no Roland users in this forum.
Probably, this forum is dominated by Yamaha users. There are Synthzone dedicated forums for roland, technics and solton, but not for yamaha. Therefore, it seems all yamaha users are in this forum. So, it has left to be a general forum, and is going to be a hidden or not recognized Yamaha forum.
Is it certain?
Nobody answer to Rolandfan? Why?
