Development of a Hexaphonic Pickup for Electric Guitars and Conversion of Analog Sound into the MIDI Format

Unlike conventional pickups for electric guitars, hexaphonic pickups generate a separate signal for each guitar string instead of a single combined signal for all six strings. This simplifies the task to convert analog guitar signals to the prevalent MIDI format for music notation and communication between digital music instruments and control devices.

The work serves as proof of concept that monophonic pitch detection can work quasi-polyphonic when using hexaphonic pickups. Moreover, the pickup and principal audio chain provide a solid platform for future works in the fields of, for instance, computer science, electrical engineering, applications related to music, and in general classical signal processing as well as deep learning applied to parallel time signals.
