Ever since i hooked up the usb ports from my mv8000 to my vista compuiter my roland wont save or it wont load any projects and also it seems that it erased all my songs that i ever worked on, when i start it up it says opertion error

The Roland G-600 is a keyboard workstation that was released in the late 1990s, and it was designed to use floppy disks as the primary storage medium for saving and loading data. However, it is possible to replace the floppy disk drive with a USB drive using a third-party upgrade kit.

Here are the general steps to install a USB drive in place of the floppy disk drive on a Roland G-600:

Purchase a third-party upgrade kit that includes a USB drive emulator and installation instructions.
Open the keyboard and locate the floppy disk drive.
Disconnect the floppy disk drive from the motherboard and remove it from the keyboard.
Install the USB drive emulator in the same location as the floppy disk drive, making sure that it is securely attached to the keyboard and connected to the motherboard.
Power on the keyboard and follow the instructions included with the USB drive emulator to configure it for use with the Roland G-600.
After installing the USB drive emulator, you should be able to use USB flash drives to save and load data on the keyboard instead of floppy disks. You may not need to update the keyboard after installing the USB drive, but it is possible that some functionality may be added or improved with a firmware update. Check the manufacturer's website or contact their support team for more information on firmware updates for the Roland G-600.

I'm not really sure what to tell you about loading your sample music. It may be a decoding issue. Check to see if has the same issue with a production music CD. As far as the hum, there can be many issues causing this. You may have a ground lead bad in the cable you are using, from your Production System to, I assume the amp you are using for the output from the Roland.

• take it back to the shop you got it from
• have you changed ports if not try a different usb port

I do not believe that the Optra E is supported by Lexmark on Vista.

Not all products from the Optra family (if any) can meet the demands of that platform.

You need to find out what motherboard you have or if your computer came with a disk. You need to load the driver of the motherboard so you can access your usb ports.

Hello,

Yes, from what I understand, it came with a floppy, CD-Rom, and a 40gb hard drive.

maybe you did not install it properly.try this turn off your cutter. plug the cable to you pc. make sure your pc is on. then turn on your cutter. then windows vista will detect new hardware then continue installation make sure you point to the correct folder. then you will see in the taskbar that says installed new hardware and ready in use. please install also the software bundled with the cutter. or if it support corel draw you can start designing and make sure that you put an outline on the object. example letter "t" put an outline on letter "t" and try plotting it. maybe this will help.

connect the printer and the comp. and boot up....windows should recognize the new device.
did you add the plotter to "add printers" and its driver and to the correct port?
make sure your plotter is on and loaded and function key pressed.
also some cable manufacturers supply a driver...so download one if need be.
what software are you using? is the software cutter driver set to the correct printer and port?
(by default it never is)!!

I had the same problem with a HP Pavilion PC running vista. The way I fixed this problem with to plug the USB into a USB port on the PC not using a ext USB Hub. I did have to go into the sound in the control panel and change the default so the other programs would use the correct sound.

The problem is a driver issue. It is strictly a LG/Verizon problem, and not Windows. What you should is hook up your phone your computer LG USB cable and using the Music Essentials CD-ROM.

Install the latest version of BitPim where  you can find at http://www.bitpim.org/ . 
"I hooked up my phone to my computer via the USB cable, and opened BitPim. Much to my dismay, bitpim did not find the COM for the LG Modem".

However, Vista popped up the window in the taskbar telling me that new hardware was detected but could not be installed. I went to Start > Search > Device Manager
Once the Device Manager is opened up, you should see an unknown hardware profile for the USB cable/phone. In my case, Vista seemed to recognize the fact that it was a LG USB Modem, but didn't have the driver. Anyway, right click on the unknown driver and select "update driver software." Surprisingly, Vista will tell you it found a driver. Unfortunately, when when you go to install the driver 2 new unknown drivers will appear.

To fix the 2 unknown drivers, all you have to do is insert the VCAST Music Essentials disk into your disk drive, and point Windows in the direction of the files for the drivers on the VCast Music Essentials CD (in my case, the D: drive).

Windows finished the install, and from their BitPim recognized the cable on COM5.
That should work.
