About a year ago, we saw a project on Hackaday.io for a MIDI wind controller. Keyboard MIDI controllers are a dime a dozen, but if you want something that actually sounds like a brass or woodwind instrument, you need something that’s controlled by a breath sensor. Since then, this project has been updated with an onboard synthesizer. It sounds great, and thanks to some interesting components, the part count is actually really low.
The synthesizer used for this project is just a single chip – the DSP-G1 from [Jan Ostman]. This isn’t a custom ASIC or anything fancy; it’s just an 8-pin ARM microcontroller in DIP format, the LPC810.
The rest of the instrument is just a series of pressure sensors along the body, and a breath sensor. The plan is to stuff all the electronics – a microcontroller to read the touch and breath sensors, the DSP-G1 chip, and the battery – inside the body of the instrument. That’s something that would be incredibly cool, and much more capable than the wind controllers that are available today.
You can see a few videos of the wind controller below.
