There are two main styles of chromatic accordion. The B System - the is played in Europe, Russia & China, and the C System that is played in the US. Most diatonic players - find that converting to B system from the diatonic keyboard is the easiest.
The music for both read the same - the button either go UP the row or DOWN the row - depending on which system you have.
Personally - I wish I had started on a Chromatic - the fingering and dexterity is so much faster on the chromatic.
