The lower keyboard is "home-made".
It is fully programmable, i can set multible Splits, Midi-Channels, convert Midi-Messages, etc...
Powered by the Audya's USB-connector, it has no need of a external power-supply.
The Keyboard is the same as the one in the Audya, witch is produced by Fatar, so it has the same Keybed and feeling as the Audya-Keyboard.
I use the Audya-Keyboard to play the Right-Part, and the Lower Keyboard to play the Left-part, splitted on F#1 to play Solo's on the right-side.
