The two devices are basically the same as far as the inside goes, including all of the Sysexs. The main difference in the two devices is that the CBX-T3 was made as an upright-standing device, presumed to be more in style for sitting next to a computer, while the TG-100 was designed for its convenience as a flat-laying device. Also, the TG-100 has an LCD display for giving information about the device while the CBX-T3 uses LED lights to indicate channel activation and primary sound bank selection.

Some CBX-T3 devices have green-lit mode buttons (such as the one pictured to the left) while others have amber/orange. There is, currently, no known reason for the different colors. Both devices should, otherwise, be identical.
