Hi Jim, I have just joined this BBS (2014) and have been looking for similar info to you (in 2008). I have had some issues setting up midi between my FR-7 and SD3 bought in December and I wonder if you were able to set it up to your satisfaction and how you have it set up? I ended up using sequencer input on FR-7 for most channels because I got frustrated trying to work using accordion MIDI channels. Bass was no problem, but trying to get bellows + accordion + SD3 sounds got too hard. If you managed to enable yours to play like an accordion but produce lovely SD3 right and left I'd be grateful for any info...I also found when I changed accordion couplers (eg master to 2 middle reed) it automatically changed the SD3 treble voice, which was unwanted. I'm sure I can do better but it's hard without user help. Anybody who has experience with this equipment, I am eternally grateful for more input please!
