<p>A music emulator (10) for emulating guitar sounds uses a piano keyboard. Input (14) within a time window is defined as simultaneous and entered into a note list. A signal is derived from the note list indicative of the chord played. Notes in the note list can be extended to form a full chord whereby as few as three notes constituting a chord are extended to a greater number of notes; e.g., a six string guitar. This signal is output (16) at a time rate which is extended with respect to the input time window whereby the output emulates a guitar strum including an arpeggiation or strumming effect. Chord extension is achieved by analyzing the notes in the note list as to their pitch and generating further notes which are outside the typical one octave range of a keyboard chord and extend to the typical four octave window of a guitar.</p> |
