I want to use my sd card to put my own songs and when i change the song from an MP3 to MIDI file using the program WIDI 3.3 Pro. When i put the MIDI file which is the song, into the Sd card and then into the keyboard it says Error Format. All i need is a program which will convert the MP3 to MIDI without any problem because the program i used mentioned above had all kinds of technical things involved which i had no idea what to do with. the song i want to put in my keyboard has a piano and violin as instruments but i only want to know how to play the keyboard bit so how do i convert the piano bit into the MIDI file so i can play it on my keyboard?????

SOURCE: Needs USB-MIDI Driver For WK 110 Piano for Windows 7(64 Bit)

Here is tie official site for the driver ... http://driverwhiz.com/drivers-en?brand=Casio&logo=Casio&subid=1001-us-en-10000000394&gclid=COT9m4uGhKACFdx05QodUT3Zkw

Evidently Casio has not written drivers for Windows 7/64 if I understand your comment. I am not that familiar with 7 but I do know in past versions, Windows has offered "compatability mode" so older devices might work with newer operating systems. Have you explored this possibility?

Here are the options I see:

Look for compatability mode on your new computer.

Ask Casio for a driver.

(I'm not a big fan of third party drivers - maybe you are - you can look for a third party driver)

Continue to operate your WK 110 using a 32 bit computer.

Thanks for your interest in FixYa.com

Does it say ERR NO FILE? If so, then read on. The reason you have this error is because you don't have a folder on your sd card named MUSICDAT. Solution:

1. Insert your sd card into computer
2. Make folder called MUSICDAT.
3. Then, transfer all files inside the folder (make sure your songs are in MIDI format).
4. Safely remove your sd card.
5. You're ready to put it in you Casio Keyboard!
