  • Page 16: Checking The Version Number

    (Project) Checking the version number in To back up the internal data of the V-Synth, you will use the V-Synth’s USB Patch mode connection in Storage mode to copy all data of the internal disk onto a drive (e.g., hard disk) of your computer.

  • Page 17: Restoring The Factory Settings

    This returns all data in the V-Synth to the factory settings (Factory Reset). Copy the program ROM file (V-Synth.rom) and the internal image file If data created by the user has already been saved in the V-Synth, all such data (V-SynthDiskImage.bin) from the CD-ROM into the drive that appeared.

  • Page 18: Test Mode

    If the above steps did not result in a successful update, please check the MA-10D etc. following two points. • Are the V-Synth and computer correctly connected by a USB cable? • Were the correct files copied to the drive that appeared on your CD/MD player etc.
