V2.0: A Teensy-based MIDI Controller

Building my own wheels for the Launchpad Pro – once again, with style.

Two weeks ago, I started a little sunday afternoon project, sucessfully building my first own MIDI controller – a pitch bend/mod wheel/midi merge device to serve as a companion to my new Launchpad Pro. Using an Arduino, a prototyping board by SparkFun, and community-made code, I succeeded with surprisingly little effort – the most time-consuming part was finding and fixing the errors I had clumsily soldered into my pathetic excuse for a MIDI interface. But it worked!

The quick and easy success made me hungry for more – I started a MIDIfication project for my JEN SX-1000 monophonic synth, based on a Teensy, another microcontroller board that can be used within the Arduino development eco-system but is much better suited to MIDI/USB applications.

This is actually a side project to that. I looked at my self-made controller and noticed that it is usable but not very playable – I wanted real wheels for the Launchpad, not sliders. So I decided to redo a V2.0 of the controller, based on the Teensy.

Homebrew MIDI Companion Controller for my Launchpad Pro

I have bought a Launchpad Pro, and am still trying to figure out how to play a synthesizer with this thing. (More on this in another post.) It’s like starting over with keyboards, only with a better understanding what this is getting at. Simply great.

One thing I don’t like about the Launchpad is that it may give you velocity and per-note pressure sensitivity – provided your synth is capable of interpreting it – but takes away the traditional performance controls of a synth keyboard: the good old pitch bend and modulation wheels we have seen as our goddamn right as keyboard players ever since they were introduced with the Minimoog.

So I decided to build my own simple Launchpad Companion Controller, based on an Arduino.
