Two issues found and fixed in the deployed UI bundle:
1. String.fromCharCode(64+y) where y is 0-based bank index
→ 64+y gives 64+0=64 = '@' for bank 0
→ Fixed: 65+y gives 65+0=65 = 'A' for bank 0
2. e.bank||1 where falsy 0 falls through to 1
→ Shows 'Bank 1' for bank 0, 'Bank 2' for bank 1
→ Fixed: e.bank||0 so 0 renders as 'Bank 0'
Source code (frontend-react/src/App.jsx) was already clean —
the bug was in a transport/song mode feature that was built
from uncommitted changes then reverted.
