Dec 24, 2007 I have an old Kawai K1 Midi keyboard, and recently decided to hook it up to Garage Band. I bought a Turtle Beach USB Midi Interface, and connected it to the USB port on my computer. I checked the help menu and checked all of the potential problem areas. The program recognizes that a USB instrument is attached, but input isn't received. Kawai USB-MIDI.zip: USB-MIDI driver for Windows XP (32 bit) and all Kawai models equipped with a built-in USB interface (USB to host). Please read the instructions in the included read me file.

well according to turtle beach no drivers are needed for OS X. Go to your UTILITIES FOLDER in your APPLICATIONS FOLDER and run AudioMidi Setup. Under Midi Devices make sure it's shown.. double click it (the Icon) and see what all it says.
Then turn it on - start Garageband - check preferences (make sure under midi it's showing up) - then add a new SOFTWARE track - select an instrument from the right - any of em and see if you can control them from your keyboard..
Also the midi cables may be reversed - they don't go like you think they would - try reversing them on the keyboard.
Here's what their site says:
*You must have at least Mac OSX to use this USB cable.*
*Mac OSX automatically loads up the driver when you plug the cable in.*
*You will NOT see any indication of anything new being plugged into the*
*computer after you plug in the cable.*
*Confirm that your Mac computer has properly installed the TB USB MIDI cable:*
*- Goto your Mac Hard Drive*
*- Goto 'Applications'*
*- Goto 'Utilities'*
*- Click on 'Audio MIDI Setup'*
*In the 'MIDI Devices' tab, you should see the TB USB MIDI 1x1.*
*If you do not see TB USB MIDI 1x1, download and install the latest OSX update*
*(10.3.9 as of this writing) and the MIDI interface will be recognized.*
*As long as the TB USB MIDI 1x1 shows up under MIDI devices, it means that*
*the TB USB MIDI cable is functioning properly.*
