Patent ID: 8319085

Claim:
Musical controller having a casing, the casing enclosing a control circuit for the processing of audio signals produced by pressing of sensors/push-buttons of the musical controller, corresponding to different musical notes, and/or by the input of audio signals in MIDI format, wherein a staff is placed on the casing, three sensors/push-buttons being associated with each note of the staff and being located on the staff, a first sensor/push-button corresponding to one of a natural note or, if a sharpened or flattened note is present on a key signature placed on the staff, the sharpened or flattened note, a second sensor/push-button corresponding to a sound which is half a tone lower than a natural note, a flattened note, or a sharpened note corresponding to the first sensor/push-button, the sound being one of a flat of a note corresponding to the first sensor/push-button, or, if a flattened note is present on the key signature, a double flat of the note corresponding to the flattened note which, in turn, corresponds to the first sensor/push button, or, if a sharpened note is present on the key signature, a natural sign of the sharpened note corresponding to the first sensor/push-button, and a third sensor/push-button corresponding to a sound which is half a tone higher than a natural note, a sharpened note, or a flattened note corresponding to the first sensor/push-button, the sound being one of a sharp of a note corresponding to the first sensor/push-button or, if a sharpened note is present on the key signature, a double sharp of the note corresponding to the sharpened note, which, in turn, corresponds to the first sensor/push-button, or, if a flattened note is present on the key signature, a natural sign of the flattened note corresponding to the first sensor/push button, audio signals, corresponding to a note, which, in turn, corresponds to a first sensor/push-button, being produced by pressing the first sensor/push-button, audio signals, corresponding to the sound which, in turn, corresponds to the second sensor/push-button and which is half a tone lower than the note, which, in turn, corresponds to the first sensor/push-button, being produced by pressing the second sensor/push-button, and audio signals, corresponding to the sound which, in turn, corresponds to the third sensor/push-button and which is half a tone higher than the note, which, in turn, corresponds to the first sensor/push-button, being produced by pressing the third sensor/push-button.
