Abstract

The present invention is an electronic musical instrument that in appearance and playing characteristics closely resembles flute-like instruments such as a conventional flute or a shakuhachi. The instrument comprises an electronic controller that has operating characteristics that resemble a flute and computer software executable on a computer for converting signals from the controller into data suitable for generating complex sound from conventional speakers. Thus, the instrument provides the complexity and nuance of control of an acoustic instrument while being capable of generating sounds that an acoustic instrument cannot make.

Claims

1. A controller for an electronic musical instrument comprising:

a housing;

a mouthpiece mounted on the housing, said mouthpiece comprising a wind separator having first and second surfaces and a microphone mounted on each of the first and second surfaces; and

a plurality of sensors mounted on the housing and positioned so that a player'"'"'s fingers can engage the sensors while the mouthpiece is held to his or her mouth.

2. The controller of claim 1 wherein the sensors are track pads.

3. The controller of claim 1 wherein there are five sensors.

4. The controller of claim 3 wherein the sensors are positioned to be engaged by two fingers of each hand and one thumb.

5. The controller of claim 1 wherein the mouthpiece further comprises a lip plate.

6. The controller of claim 1 further comprising an amplifier for amplifying output signals from each microphone.

7. The controller of claim 1 further comprising a microprocessor for processing signals from each track pad.

8. The controller of claim 1 further comprising a wireless transmitter for transmitting signals from the microphones and sensors.

9. The controller of claim 1 wherein each microphone functions as a signal amplitude sensor responding to friction noise resulting from blowing of air directly onto the microphone.

10. The controller of claim 1 further comprising a third microphone mounted on the mouthpiece to amplify a player'"'"'s breath sound in conventional fashion.

19. The electronic musical instrument of claim 1 wherein the first synthesizer is implemented in computer software.

11. An electronic musical instrument comprising:

a controller comprising;

a housing,

a mouthpiece mounted on the housing,

said mouthpiece comprising a wind separator having first and second surfaces and a microphone mounted on each of the first and second surfaces; and

a plurality of sensors mounted on the housing and positioned so that a player'"'"'s fingers can engage the sensors while the mouthpiece is held to his or her mouth;

a processor for processing signals from the microphones to produce a first output signal;

a processor for processing signals from the sensors to produce a second output signal; and

a first synthesizer responsive to said first and second output signals to produce a first sound synthesis signal for controlling an audio speaker.

12. The electronic musical instrument of claim 11 wherein the sensors are track pads.

13. The electronic musical instrument of claim 11 wherein there are five sensors.

14. The electronic musical instrument of claim 13 wherein the sensors are positioned to be engaged by two fingers of each hand and one thumb.

15. The electronic musical instrument of claim 11 wherein signals from the microphones are processed to determine a ratio of the amplitude between the two microphones.

16. The electronic musical instrument of claim 11 wherein signals from the sensors are processed to determine fingering events including the number of fingers on the sensors.

17. The electronic musical instrument of claim 16 wherein the fingering events include vented fingerings and non-vented fingerings.

18. The electronic musical instrument of claim 11 further comprising:

a noise generator;

a second synthesizer responsive to said first and second output signals to produce a second sound synthesis signal for controlling an audio speaker; and

an amplitude envelope generator for combining an output of said noise generator and said first and second sound synthesis signals.

20. A computer software program embedded in a recording medium, said program comprising instructions for:

detecting fingering events on a plurality of sensors;

detecting blowing events received on at least two microphones;

determining data representative of the fingering and blowing events; and

using such data to synthesize at least one sound signal suitable for controlling an audio speaker.
