When you absolutely, positively must have the finest, most advanced accordion money can buy, look no further than the Roland FR-2. With an astounding eight (eight!) separate virtual accordion sounds, 128 note polyphony, pneumatic (high-resolution) detection of bellows pressure, 15 micro-tuning regional presets, MIDI functionality, AA battery power, chorus and reverb effects, and integrated pad triggers for sampled percussion (or shouts of "Get funky!"), this is the Rolls-Royce of digital accordions. Unless, of course, you count the Rolls-Royce Digital Accordion. Phantom or Silver Shadow models notwithstanding, for $3,000, you can't go wrong.
