For users running Windows 10 or Windows 8.1, version 2.8.1 represents a significant milestone in the software’s evolution, as it was the last version to officially support the 32-bit architecture of these older operating systems before Yamaha transitioned to an exclusive 64-bit requirement in subsequent updates.
