Abstract:
A reed accordion has a set of note generators each coupled to a respective key and is connected through a plurality of tone filters to an output. Each filter corresponds to a respective organ voice and is controlled by a respective tab which disconnects its filter from a bus (otherwise common to all filters) when actuated and thereby renders it operative. A plurality of registration program cards removably received in multicontact sockets on the instrument each carry a registration program network which is connectable through a respective registration switch to selected filters such that actuation of this switch will automatically cut in selected filters by disconnecting them from the bus. Each card bears two registrations in the form of conductors printed on its two faces so that simple scratching-through of a conductor programs that network for the respective organ voice, allowing the user to establish his own organ-voicing programs. A further switch, in one position, permits the accordion treble shifts to operate without preprogrammed organ-voicing and, in another position, provides programmed organ voicing for each treble shift.
Abstract:
A music re-performance system allows a plurality of untrained instrumentalist to play pre-stored music using traditional playing techniques along with an automatic accompaniment at a tempo controlled by a selected-instrumentalist. Instrumentalist's gestures start and stop pre-stored score notes and temporal restrictions limit gestural timing errors. Expression parameters, including volume, timbre, and vibrato, are selectively updated, allowing editing of music sound files. A finger manipulation and energy driver controller model, including transducers and signal processing, accommodates wind and string instruments. Temporal masking prevents substantially concurrent finger and energy gestures, intended as simultaneous, from producing multiple false gestures.
Abstract:
Method for storage, transcription, manipulation and reproduction of music on system-controlled musical instruments which faithfully reproduces the characteristics of acoustic musical instruments. The system comprises a music source, a Central Processing Unit (CPU) and a CPU-controlled plurality of instrument transducers in the form of any number of acoustic or acoustic hybrid instruments. In one embodiment, performance information is sent from a music source MIDI controller to the CPU, edited in the CPU, converted into an electrical signal, and sent to instrument transducers via transducer drivers. In another embodiment, individual performances stored in a digital or sound tape medium are reproduced at will through the instrument transducers, or converted into MIDI data by pitch/frequency detection/analyzation device for storage/editing/performance in the CPU. In still another embodiment, performance information is extracted from an electronic recording medium or live performance by a pitch/frequency detection/device, edited in the CPU, converted into an electrical signal, and sent to any number of instrument transducers. The device also eliminates acoustic musical instrument delay problems.
Abstract:
A method for electronic generation of sounds, based on the notes in a musical scale, including assigning respective sounds to the notes, such that each sound is perceived by a listener as qualitatively distinct from the sound assigned to an adjoining note in the scale. An input is received indicative of a sequence of musical notes, chosen from among the notes in the scale, and an output is generated responsive to the sequence, in which the qualitatively distinct sounds are produced responsive to the respective notes in the sequence at respective musical pitches associated with the respective notes.
Abstract:
In the present invention, performance sample passages are used as source material to drive the transducers of a controlled musical instrument, such as the strings of a violin. The performance sample passage method permits the faithful recreation of a musical performance without the limiting effects of speakers. Alternatively, analog/digital synthesizers, tape or other recording media, monophonic/polyphonic pitch recognition/MIDI conversion methods or any electrical signals are used as sources to drive the transducers of a controlled instrument. The invention uses magnets with steel pole pieces positioned on either side of a transducer, such as a metallic string or rod of a controlled instrument. Said metallic string or rod can be either double or single anchored, or utilize any combination of anchoring means. Insulation between the pole pieces and magnets is utilized to isolate the coils from the magnets and pole pieces. String dampers are used to recreate a violin bow's damping and string focusing effects.
Abstract:
A fiber optic musical instrument provides a design in which the musical notes and characteristic instrument sounds normally sensed by electro-mechanical devices such as magnetic pickups and acoustic transducers are generated by the modulation of light within optical fibers and are optically transmitted to amplifying devices without the need for externally mounted sensing devices.
Abstract:
A system for coding voice signal to optimize bandwidth occupation in a High Speed Packet Switching network while ensuring best voice transmission quality.The voice signal is first encoded using a conventional GSM like RPE/LTP coder providing first sub-frames of coded signal and tagging these first sub-frames as being non-discardable. In addition, a convenient difference between an RPE/LTP provided signal and a corresponding synthesized image is performed (see 36) and is also block encoded into second sub-frames which second sub-frames are tagged as being discardable sub-frames. Said second sub-frames when concatenated to corresponding first sub-frames provide so-called multirate frames. Then, when transmitting said multirate frames over the High Speed packet switching network, dropping discardable tagged data enables solution network congestion situations in any network node and at random with no significant disturbing effect over the voice communication operation.
