Breath-controlled MIDI device prototype demo

Описание: This is my prototype for a breath-controlled MIDI device. It is controlled by an Arduino Micro, has 35 note buttons and uses a pressure sensor to translate breath intensity into any MIDI signal. On the underside, there is also another button which can serve as a sustain pedal or as an octave shifter, and a soft pot which can be used for any MIDI signal.

In the first video, I am playing violin 1 for RVW's Phantasy Quintet, with the breath sensor controlling the Mod Wheel parameters, which in turn controls master volume, white noise volume (to simulate the bow sound), and a low pass filter's cutoff frequency. The second video shows the opening bassoon solo from the Rite of Spring, with the breath controlling similar parameters.

As stated above, the device has 35 note buttons, which can be used to play single notes or chords. The buttons can be set to various parameters. For example, while by default they are set to a chromatic scale, the device supports various modes, like the usual church modes, whole tone, octatonic, and more. It is also possible to set the starting and octave pitch of the lowest note.

While both the breath sensor and soft pot support various MIDI modes like regular CC, mod wheel, pitch bend, etc., the breath sensor has the added option of having an adjustable sensitivity.

It is also possible to save and load configurations into the ATMega's integrated EEPROM.
