It will do the Nashville number system as we as Do-Re-Mi.... it's quite capable of speaking several languages musically speaking.
Are the "several languages" expressed like this?
1-4-5 = C-F-G in the key of C
1-4-5 = D-G-A in the key of D
1-4-5 = E-A-B in the key of E
1-4-5 = F-Bb-C in the key of F
Etc.
