How to look like a prat live on stage
The Rockband 3 Wireless Keytar has no reason to have a midi-out port, or a mod wheel and pitch bend control, octave up-down buttons, program change buttons, a velocity-sensitive 2 octave keybed, or a wireless USB receiver. And yet, it has all of these things. It costs less than £40 secondhand, comes with a strap, and I'm currently using it as a wireless controller for my Nord Electro 6.
Because I was so preoccupied with whether or not I could, I didn’t stop to think if I should.
The USB receiver on the keytar allows it to be plugged into a computer, and some sort of driver/midi software combo can be leveraged to turn this into a fully functioning midi device. I really don't like bringing my laptop to gigs though, so in comes the Raspberry Pi.
Keytar -> Wireless Receiver -> Pi -> USB Midi cable -> Nord
A kind soul has made a driver that converts the raw output of the keytar into midi messages. After installing this on the pi with a fair amount of difficulty and swearing, and getting the script to start at boot without the need for any user input, the pi becomes a plug 'n' play device for Nord-keytar communication. Finally, I can take my funk solos with style, as long as I remember to keep an eye on the keytar battery life. At least if the batteries run out I can preserve some dignity.
