The Edt-2000 ecosystem

A project log for Edt-2000: Expressive midi controller

Experiments to turn a 'GameTrak' controller into an expressive midi controller for live shows.

Last night we had a meeting about the direction of the project and things we encountered. In short, Thomas has been very busy creating all kinds of custom libraries and experiments with Sparkfun 'Things', wireless microcontroller that is cheap and has battery support build in. Edwin has been playing with EL-Wire and thinking about the system as a whole, mostly because he has been busy with lots of things.

Steven, as always, has been busy making electronic music and has ordered an extra Synthesizer: the Novation Mininova!

This thing is insane!

But, a bit more about the project which is called the Edt-2000; we are generating more and more names for each component!

Edt-Trak & Edt-Pedal

This is the starting point with the original idea: a modified GameTrak controller that can control midi instruments. Because we want to be able to switch between presets we are making a control pedalboard, so that it becomes easy to control stuff on stage with some simple foot switches. We haven't really figured out which switch does what, but hey; switches! Always fun!

Edt-Strobe & Edt-TOP & Edt-FadeLight

A good live show is nothing without cool lighting. We came up with 3 important elements: a stroboscope or bright LED that can be triggered, an Edt-Top (Tower of Power) that is simply a strip of LED's that can be placed easily anywhere on the stage and the Edt-FadeLights; a few simple bright RGB LED's (or DMX dimmers) that fade light in or out when you raise your hands (or do anything like that).

Edt-Chuck & Edt-Suit

We want the performers to have a cool suit, with lights and EL-Wire, just because we can. The Edt-Chuck will be a nunchuck controller that wirelessly communicates with the rest; and can be used to give more fine control over which parameters you control and what kind of things happen with the music and lights.


We finish this log with the Edt-MOSCidi, which is also one of the most important components to create a flexible system. Through experiments we discovered that OSC is a fast and reliable protocol to use for our communications; but we do need a way to bring OSC messages into a midi device like the synth or the drum computer. A powerful Arduino (or maybe Netduino) will become a bridge between OSC messages and Midi messages, so that you could control your synth with only the Edt-Trak and the Edt-MOSCidi.

If you have some remarks, thoughts or ideas; please let us know, we are happy to help/discuss any questions you might have.
