About KeyLevel 88 Regulation Map
KeyLevel 88 Regulation Map is a local-first workbench for independent piano technicians and small regulation shops. Map the complete physical A0–C8 keyboard, preserve stable key identity, and record technician-entered regulation measurements without pretending to measure or diagnose the piano automatically.
