https://www.youtube.com/watch?v=bM7NN-fiMXs In this project we're building a diy midi controller that works with ios devices and analog synths. Say hello to oontz, the open source button grid controller based on the adafruit trellis. The mini oontz is a 3d printed case housing one trellis and 4 potentiometers ideal for a 16 button drum pad making a compact music instrument. Get the tools and parts for this project from Adafruit. Full Tutorial https://learn.adafruit.com/mini-untztrument-3d-printed-midi-controller Install the oontz libraries and program the arduino leonardo to make a native usb midi controller. use our demo sketches to get your oontz lit up. Learn all out midi oontz library and how you can build your owb by checking out the guide on the adafruit learning system. The 16 buttons trigger leds and midi notes that are mapped to this table in the arudino demo sketch. The potentiometers are mapped to midi cc's like modulation, expression and filter cut off. Connect it to an iOS device using the camera kit usb adapter for a mobile production setup. Use your laptop and a midi to usb interface to control an alalog synth. For a massive midi controller, check out the hella oontz, feauring 128 buttons. Perfect for making a step sequencer or an arppegio that is hella hackable. Add Oontz to your arsenal of midi weapons. Oontz works with any midi software and hardware. No more virtual midi or serial to midi stuff, oontz is legit USB midi. What awesome sensors and features would you use to make your own custom oontz?
