Accidentally found this in during a search for information about MIDI devices…
The best part:
“Sound output via built-in stereo amplifier and loudspeakers, stereo headphones and stereo line-out.” 
That’s just weird. Kinda takes the reed outta free-reed.
electronic pipes are for deaf wimps.
Of course I’m thinking GHBs here. The real ones are for deaf or soon to be deaf masochists.
for practicing this looks like a godsend… there’s no way to mute an accordeon so it’s not terribly family- or neighbor-friendly. MIDI piano accordions have been around for years, it’s about time somebody came up with a buttonbox version.
Oh thanks so much ava… now I want one of those as well as a saxoflute! 
Well, if I get one, you can borrow it.
