I have been playing with the pre-loaded Accordion sound a bunch—it seems to sound really nice, particularly lead melody for tango or gypsy jazz style music. Rhythm chords don't sound quite as authentic IMHO, but are ok. Actually I really prefer setting up a split to have rhythm piano and accordion lead.
I'm curious if there are any players here who have a real accordion who could compare and contrast some of the differences between the sample and the real deal and also playing methods for maximizing the realism of the sound. I'd actually like to get an accordion some day, but I already have an NS2 and kinda know how to play it today.

Thanks for any thoughts or insights!
Cheers,
