Why would they ? There are many manufacturers working with the C-2 to G8 definition of the midi range … they’ve adopted this version of the ‘reference’ standard
why don’t you just offset two octaves
keep in mind anyway , a C0 (standard-a) is still just a reference to midi note 0, so whether it’s listed as c-2 (standard-b) or C0 is irrelevant, just feed the machine the right midi note irrespective of the relation to a standard … at the end of the day, the midi note is the only important thing …
