When playing a song on both a GCF and a FBbEb, are you pressing the same buttons in the same positions? I know it's the same on single row boxes between the different keys, but am not sure about triple rows.
Thanks

more or less, yes
the triple rows may have 'more or less'
buttons on the ends
some of the rows are shorter
and some boxes just have an extra button
on the high-note side

plus, they all have the 'chromatic' buttons
on the low-note side
what these are, are 3 buttons, which
add the 3 notes that you would need to play
any of the 12 chromatic notes, that are
not already in one of the rows

but out in the middle of the pattern,
the main playing area,
the same note relationships apply,
from row to row, and from 3 row box to one row box
