Missing support for OS X

By Anonymous

from Undisclosed

Don't buy this keyboard if you are want something to work with OS X. Casio doesn't have drivers to enable you to connect via USB and the keyboard doesn't have any standard MIDI ports.

This keyboard is awesome. It comes with an SD slot for whatever you want on it. Although its USB port is type B, it is great to learn and become a legend on. 61 keys is a great size, and the light-up keys are excellent to start playing along with songs.
