I just finished reading the MM6 manual and it certainly has possibilities for anyone not needing a full-blown arranger keyboard. For those of us who have one foot in hardware and the other in emerging software, this is an attractive and less expensive solution. From the manual it is clear that at least root chording with auto-accompaniment is possible, so it is a basic arranger.
I know little about the Motif line and the use of "patterns" in the Yamaha offerings. Does anyone here have an opinion as to whether new patterns can be introduced into the MM6, as "performance" data or something else? I saw nothing about this. It is expected that patterns from any of the MO line would be usable?
