Digital Warrior – The final battle

After the release of the Sequencer Edition last November I’ve worked more on improving a little bit the enclosure. My main goal was using a little bit better materials and closing up the sides, for a more solid, finished feel. After a lot of thinking and design iterations I ended up “borrowing” an idea from … Read moreDigital Warrior – The final battle

Digital Warrior Sequencer Edition

I am happy to announce the release of a third Digital Warrior edition. The new hardware controls are focused on the stand alone sequencer firmware, turning the MIDI controller into an full blown 4 track monophonic MIDI synth sequencer. The new expansion board adds a small 7segment display and 3 buttons that help in the programming … Read moreDigital Warrior Sequencer Edition

Plug controller

I’ts been a super fantastic week here in Cyprus during the Plug electronic music conference. Full of workshops, parties and amazing new people to meet. During one of the last day I had the opportunity to do a workshop on diy midi controllers. I designed and produced a basic midi controller kit based on Teensy … Read morePlug controller

MIDI Elements Teensy Library V2

After quite some time, I finally found a chance to update the MIDI Elements library, improve some features and make a proper documentation for it. After a lot of requests I added a class for endless encoders and RGB LED’s. Also added mapping features for the Potentiometer class that makes it easier to use with … Read moreMIDI Elements Teensy Library V2

MIDI Elements Teensy Library

I have created a wrapper library to make programming MIDI controllers on the Teensy board dead easy and super fast. Simply instantiate object for each component like Buttons, Potentiometer, LED, rotary encoders, etc. and let the library handle all the dirty work of reading the raw values and deciding when to send MIDI signals. Enabling you to experiment and concentrate on your creative ideas and not waste too much time with the repetitive technical details and debugging code.

Just in a couple lines of code you can program a fully functioning MIDI controller.
Here’s an example of how simple things are:

boolean debug=false; // print to serial instead of midi
boolean secondary=true; // enable secondary midi messages
int midiChannel=1; // midi channel number

// declare all your components here
Button but(17,midiChannel,1,secondary,debug); // button 1 on pin 17
Button but2(16,midiChannel,2,secondary,debug); // button 2 on pin 16
Potentiometer pot(45,midiChannel,3,secondary,debug); // knob on pin 45 (A7)
Led led(15,midiChannel,3,true); // led on pin 15 with PWM enabled, triggered on the same number as pot

void setup(){
  usbMIDI.setHandleControlChange(OnControlChange); // set event handler for CC

void loop(){
  // add here all the input component reads; // read knob and send midi messages; // read buttons and send midi messages;; // read all the incoming midi messages
// event handlers
void OnControlChange(byte channel, byte control, byte value){
  // add all your output component sets that will trigger with cc

Currently only Buttons, Potentiometers and LEDs are supported. But I’m planning on adding RGB LED, rotary encoder, LED bars and ring and button pad classes.
Each component sends two sets of MIDI signals if enabled. For example Buttons send NoteOn, NoteOff, as well as ControlChange values so that they could be easily mapped in Toggle or Instant mode in software like Ableton Live. Also the Potentiometers send secondary NoteOns when values reach 0 or 127, à la MIDI Fighter Pro.

Aftertouch MIDI Glove

It’s been a while since I posted a new project here, but after the Moving Silence festival I got so fascinated, inspired and charged with this creative energy that shortly after I just knew exactly what I was going to do. At first it occurred to me that so far I’ve been working on mostly … Read moreAftertouch MIDI Glove
