> Isn't it something to do with the French for flat: bemol? At a guess. Is this the "b" for flat? (like G_flat = Gb) but this doesn't explain why a "flat H" is called "B" (and not "Hb") So unfortunately "B" is ambivalent. it can mean a flat B (aka flat H) or a natural B. So I chose "H" and "A#" on the front panel. JB. (;->)
