We designed this kit for ease of use and ultimate flexibility. All you need is an Arduino Leonardo, basic soldering tools and an afternoon. Once assembled and programmed with the Arduino IDE, this box turns into a USB MIDI device that works with any computer and has 64 buttons with controllable LEDs. Our default example program sends a MIDI Note On and Off message for each button press but with a little programming ingenuity you can send and receive any kind of MIDI command. Since its USB MIDI it can work instantly with just about all synth software. Don’t like MIDI? The Leonardo can also emulate a USB keyboard or plain old USB serial.
Since it’s Arduino-powered, adding more stuff like accelerometers, potentiometers, rotary encoders, etc. is straight-forward and uses existing libraries available on the Internets. If you want to add some knobs, rotary encoders or pots, check out the UNTZtrument accessory plate.
Each order comes with:
- Four Trellis control PCBs
- Four matching Trellis Elastomer button pads – 64 total buttons
- An LED pack of diffused white 3mm LEDs – 70 total LEDs, so you have a couple extra.
- Custom designed laser-cut enclosure, clear body and black top
