Breath controller

Background

To play wind instruments more realistic if you are a keyboard player, a breath-controller is a good option: You select the notes to play with your keyboard, but the sound is triggered and articulated based on your breath.


How it is build

Usually people (like me) use instructions like this only for own inspirations, so this is not meant to be a full "how-to-build" instruction, but it should give you enough insights to do so if you want. In the rare case you really build this and make it to work please drop us a mail :-)

All parts are laser-cut from a very thin (0.5mm) like acrylic sheet and a thicker (4mm) acrylic plate. The 0.5mm acrylic is more like a foil and much more flexible than the 4mm glass like sheets. These are the files with the laser cut parts made with Inkscape:
