MIDIO — A MIDI microphone

The aim of this project was to create a more effective and efficient tool for MIDI composition than is currently available. I wanted to create a tool that could lever any instrument as a MIDI controller, from a trombone to a person whistling. Secondary controls were introduced using a MIDI foot pedal to have further control of the software instrument. Knobs on the software instrument could then be controlled in real-time with the foot pedal along with the melody using an instrument, allowing the user to capture a human performance.

Project Description

MIDIO is a real-time monophonic audio to MIDI converter for MIDI composition. MIDI (Musical Instrument Digital Interface) is a standard way for digital instruments to communicate with one another and compose music. The main interface for this is a MIDI keyboard. The most common alternative to MIDIO is to simply use a mouse and keyboard; and clicking in the notes across a timeline. This method is ineffective as the keyboard is only useful for piano players, moreover the mouse and keyboard method is not stimulating to a musician, inefficient and does not promote creativity in composition. MIDIO is a tool to provide leverage for any instrument as a MIDI controller. I conducted research into similar tools on the market, software synthesiser composition methods and wider computer music composition methods through end-user interviews and a literature review. The idea that transpired was a real-time audio to MIDI converter that could use any monophonic audio signal as a means to control a software synthesiser. Secondary controls were introduced using a MIDI foot pedal to have further control of the software instrument. Knobs on the software instrument could then be controlled in real-time with the foot pedal along with the melody using an instrument, giving more tight control of the software synthesiser and allowing the user to capture a human performance.

Project Findings

The primary function of this tool was achieved; a real-time audio to MIDI converter was developed. Further development is needed to reduce the amount of noise in the MIDO output. Therefore MIDIO's compositional tool features need to be enhanced. Going forward, this will be addressed in future builds of MIDIO to make it compatible with MIDI composition.
