Abstract
The apparatus includes a plurality of foot-operated switches, each switch associated with a particular musical note in a selected octave. Additional switches are provided for tempo (beat control) and selection of minor and seventh chord variations. The apparatus includes a processor which produces messages, in response to the switch selections, which have a MIDI format wherein the messages are transmitted to any music sequencer which can use the information therein to produce the audio signals which when amplified and sent to speakers produce the musical chords which the selected switches represent.
Claims15
An apparatus for controlling a music sequencer which is separate from and independent of said apparatus and which is capable of accepting control signals from an external source, wherein said apparatus is not itself capable of producing audible music, comprising:
- a switch means comprising a plurality of switches individually operable by an operator, each switch representing, respectively, a different musical note which is in turn associated with a preselected musical chord;
- processing means for scanning said switches and responsive to closure of one of said switches which is associated with a particular musical chord to produce an output signal in the form of a control message in MIDI language format recognizable by music sequencers and representative of the musical chord, which will cause the music sequencer to produce signals which can in turn be used to generate audible accompaniment music in accordance with said preselected chord;
- and
- means for transmitting said message to the said separate music sequencer.
