MrEd ... just saw the demo ... WOW ... both guys played very well, but the guy on the button accordion was amazing ...

Thinking back to my accordion days, we would play full classical scores - Beethoven, Rossini, etc. etc. utilizing the various reed sets to emulate the different pitches of the symphony orchestra instruments ... (even played in Carnegie Hall) ... I can see that there could be a competition 'class' for digital accordions using the orchestral sounds and actually sounding like a symphony orchestra ...
