Hello: Thanks for sending the instructions. Since I have not created anything on the Motif, I guess I shouldn't worry about backing up any data. I assume nothing is going to happen to the original sounds that come with the Motif right? Well, thank you very much once again. Have a great day. From: Edu Camargo Sent: Saturday, February 20, 2010 1:51 AM To: MoAccess@xxxxxxxxxxxxx Subject: Re: [MoAccess] question on updating motif XS OS Below are the procedures to be taken, as documented by Yamaha itself, including important notes. ---------------- Updating Procedure --<Caution>-- - If you are updating to V1.55 from V1.50 or an earlier version, all User data (User Voices, User Performances, Songs and so on) will be initialized by this updater. ----------------- You can save all user data to a USB storage device or to a computer connected to the same network by selecting "all (file extension is .XOA)" as the saved file type and executing the save in the File mode. For details, see page 276 of the Owner's Manual. Required Items - One USB memory device of over 256MB capacity formatted on the MOTIF XS 1. After downloading, copy the uncompressed [8E54OS_.PGM] file to a USB memory device that has been formatted on the MOTIF XS. No other files should be present on the USB memory device. 2. Power off the MOTIF XS. 3. Connect the USB memory device copied in step 1 into the MOTIF XS. Power on the MOTIF XS while holding down the cursor [UP] button and [UTILITY] buttons until the "MOTIF XS" logo appears on screen. 4. The MOTIF XS OS updater will begin with the message "Searching for the firmware updater," indicating "......%". When the message "Finish. Please turn off " appears, turn off the MOTIF XS and remove the USB memory device. NOTE: The update process takes about fifteen minutes. DO NOT power off or remove the USB device from the MOTIF XS during this time. If the electrical supply is accidently interrupted while running the updater (by pulling out the AC cord, etc.), the unit may become inoperable. If this happens, run the updater again. If the unit does not function after doing this, please contact your nearest Yamaha service center. 5. If you are updating to V1.55 from V1.50 or an earlier version, make sure to execute the Initial Factory Setting by pressing [UTILITY] -> [JOB] -> [ENTER]. After the Initial Factory Setting is completed, load the data you backed up before this procedure to the MOTIF XS, if necessary. 6. Press the [UTILITY], [Cursor Up] and [F1] buttons simultaneously to check the firmware version to confirm that the unit has been successfully updated. This concludes the update process. A note from me: The Motif XS logo appears after 5 secs or so, and just to reiterate, the update process begins immediately. Just remember, for the update to start, you should press the power with cursor up and the utility buttons simultaneously. Hope this helps. Peace, Edu Camargo. -- ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ My Music at myspace.com
