Engineers, hackers, and makers can most certainly build a musical gadget of some kind. They’ll build synths, they’ll build aerophones, and they’ll take the idea of mercury delay line memory, two hydrophones, and a really long tube filled with water to build the most absurd delay in existence. One thing they can’t seem to do is build a woodwind MIDI controller. That’s where [J.M.] comes in. He’s created the Open Woodwind Project as an open and extensible interface that can play sax and clarinet while connected to a computer.

If you want to play MIDI, there are plenty of options for keyboards, drum sets, matrix pads, and even strings. If you want to play a MIDI saxophone, there aren’t many options. Keytars, for example, are more popular than MIDI woodwind controllers. [J.M.] is changing this with a MIDI controller that recreates electronic aerophones electronically.

The controller itself uses a Teensy 3.2 loaded up with an ARM Cortex M4, two MPR121 touch controllers for 24 channels of capacititve touch capability, and a pressure sensor to tell the computer how strong the user is blowing. All of this works, and [J.M.] has a few videos showing off the capabilities of his homemade controller. It’s a great piece of work, and there are a few extentions that make this really interesting: there’s the possibility of adding CV out so it can be connected to modular synths, and the addition of accelerometers to the build makes for some very interesting effects.
