An Expressive Vocal Midi Controller, Brady Hurlburt

Electrical Engineering Undergraduate Honors Theses

The choice of controller often characterizes the performance obtained from an electronic instrument. Controllers exist that allow electronic musicians to mimic the expressive qualities of keyboard, wind, string, and percussion instruments, but vocalists have been largely neglected. To fill this need, a realtime software vocal MIDI controller named Grove is developed and demonstrated. Grove's pitch and time analyses are shown to be accurate, and it has mappable control signals that go beyond the capabilities of previous audio-to-MIDI converters to facilitate an expressive performance. Grove's source code is available under the GNU GPL v3 license.
