String array signal processing for electronic musical instruments
Abstract:
System and method expanding and generalizing string selection aspects of an autoharp and applying to general forms of string arrays. String vibration may be sympathetic or induced by strumming, plucking, and/or electrical drive transducers. Volume of individual vibrating strings within arrays of strings may be mechanically or electronically controlled by chord buttons or a music keyboard. Electronic control can also be made with foot switches or incoming MIDI control signals. These controls may be used individually or in combination. Keyboard keys may be provided with key-travel sensors, key-surface sensors, or other sensors for continuously controlling volumes and octave mixings of subgroups of individual strings. Incoming MIDI control signals may also be used for controlling volumes and octave mixings of subgroups of individual strings. Outgoing control signals, such as MIDI, may be generated responsive to the plucking and/or the amplitude of and harmonic structure in the ongoing vibration of individual strings.
