One question, out of curiosity, is the chromatic button accordion at all popular in Latino music? I know they play a lot of button accordion (not counting the bandoneon, the popular free reed instrument in Argentinian tango), but from what I've seen it's exclusively a keyed button accordion, e.g not chromatic and has none of the transposition benefits of the chromatic, which is, as you pointed out, the dominant style in Eastern Europe and Russia (where it's called a bayan). But if Latino musicians are playing chromatic button accordion too, that's cool.
