Back in the day I had a Casio WK-110 keyboard. It had touch response, 77 keys, and General MIDI. I thought "Not bad for $200!" However, upon opening I discovered that it lacked MIDI ports and instead used a USB connection to transmit MIDI data. The provided CD did not work in Mac OS X and I thought I was up a creek without a paddle.

Luckily I have some experience with working with MIDI instruments and I was able to find drivers that would allow it to work, but this required some searching as Casio did not provide the drivers themselves. To prevent ya'll from hitting a lot of dead ends, I'm here to help you get your Casio WK-110 working on Mac OS X so that you can use it with programs like Garage Band and Finale!

Like I said before, proper Macintosh MIDI drivers for the WK-110 are nowhere to be found on Casio's website. After some research I found a solution, and from Yamaha ironically. Turns out Yamaha makes some USB-MIDI keyboards similar to the Casio and that their driver patch will work with your WK-110. So do a Google search for "Yamaha USB-MIDI Drivers v1.1.0 for Mac OS X." This should bring up a bunch of websites that offer the driver. Choose one (MacMusic.org is where I got mine) and download it.

Yamaha has the latest version of the Casio WK-110 compatable MIDI driver here.

Installation is very simple. Search for a folder called "MIDI Drivers." It should be located in Library-->Audio-->MIDI Drivers. Then just drag and drop the downloaded driver to the folder! It should work right away, but you may need to restart just in case.

Now just plug in your keyboard to the nearest USB slot, turn it on, and open up Garage Band or another program and it should be recognized! Happy composing!
