Everyone's been blogging the Roland FR-7 Midi Accordion, but it's not a new thing. For $900-$1,800 any accordion can be retro-fitted for MIDI, or my good friends at accordionsandkeyboards.com have a big range of MIDI accordions, and chic-looking sound modules (complete with lots of auto rhythms) to plug them into. And Cavagnolo are a French company (obviously) who've been making MIDI accordions since 1984.
