Computer input from music devices

A system for interfacing tones with a computer, comprising:

• one or more inputs;
• one or more outputs;
• a microprocessor configured to:
• receive, through the one or more inputs, a digital signal representing one or more note events each having a pitch, a velocity and an initiation;
• identify a group of concurrent notes from the one or more note events;
• in accordance with a pitch class of a base note of the group of notes and intervals computed between pitch classes of the notes of the group as ordered by the pitch of the note events, translate the group of notes into a computer input signal representative of one or more keystrokes on a computer keyboard;
• and
• send the computer input signal through the one or more outputs to a computer for output or further processing.

A method for interfacing tones with a computer, comprising:

• from a musical instrument, receiving an analog signal representing one or more tones each having a pitch and a volume;
• identifying a group of concurrent tones of the one or more tones;
• in accordance with a pitch class of a base tone of the group of tones and intervals computed between pitch classes of the tones of the group as ordered by the pitch of the tones, translating the group of tones into a computer input signal representative of one or more keystrokes on a computer keyboard;
• and
• sending the computer input signal to a computer for output or further processing.
