Abstract

An electronic music system has an input device, one or more computer storage media, a rhythm generator, a pitch selector, and a sound generator. The input device generates rhythm-related input signals and pitch-related input signals in response to manipulations of the input device by a user attempting to create and play a solo. The computer storage media have a plurality of user-selectable musical accompaniment tracks over which the user can create and play the solo and a plurality of rhythm blocks wherein each rhythm block defines, for at least one note, at least a time at which the note should be played. The computer storage media also store at least a portion of the solo created by the user over a predetermined time interval in the immediate past. The rhythm generator receives the rhythm-related input signals from the input device, selects one of the rhythm blocks from the computer storage media based on the rhythm-related input signals, and outputs an instruction to play the note at the time defined by the selected rhythm block. The pitch selector receives the pitch-related input signals from the input device and selects an appropriate pitch based on the pitch-related input signals, the user-selected musical accompaniment track, and the stored solo information. The pitch selector then outputs that appropriate pitch. The sound generator receives instructions from the rhythm generator, pitches from the pitch selector, and the user-selected musical accompaniment track and generates an audio signal representative of the user-created solo and the accompaniment track.

Claims

1. A system for creating music in real time, comprising:

an input device including at least a first axis of manipulation and a second axis of manipulation, the input device for providing rhythm-related signals in response to a user'"'"'s manipulation of the input device with respect to the first axis and for providing pitch-related signals in response to the user'"'"'s manipulation of the input device with respect to the second axis; and

a real-time music generator for receiving the rhythm-related and pitch-related signals from the input device and creating in real time music comprising (i) pitches based on the pitch-related signals and (ii) rhythmic activity based on the rhythm-related signals.

2. The system of claim 1 wherein the input device comprises a joystick having a movable handle which the user manipulates along the first axis to cause the joystick to provide the rhythm-related signals and along the second axis to cause the joystick to provide the pitch-related signals.

3. The system of claim 1 wherein the input device has the first and second axes arranged perpendicular to each other.

4. The system of claim 1 wherein the input device comprises a continuous controller.

5. The system of claim 1 wherein the input device comprises a mouse.

6. The system of claim 1 wherein the input device comprises a tracball.

7. The system of claim 1 wherein the input device comprises a fader.

8. The system of claim 1 wherein the input device comprises a slider.

9. The system of claim 1 wherein the input device comprises a spatial sensor.

10. The system of claim 1 wherein the input device comprises a discrete controller.

11. The system of claim 1 wherein the input device comprises a game pad.

12. The system of claim 1 wherein the input device comprises a plurality of switches.

13. The system of claim 1 wherein the input device comprises a plurality of buttons.

14. A method for creating music in real time, comprising:

(A) receiving rhythm-related signals provided in response to a user'"'"'s manipulation of an input device with respect to a first axis of manipulation of the input device;

(B) receiving pitch-related signals provided in response to a user'"'"'s manipulation of the input device with respect to a second axis of manipulation of the input device; and

(C) creating in real time music comprising (i) pitches based on the received pitch-related signals and (ii) rhythmic activity based on the received rhythm-related signals.

15. The method of claim 14 wherein:

step (A) comprises receiving the rhythm-related signals which are provided in response to the user manipulating the input device along the first axis which is perpendicular to the second axis; and

step (B) comprises receiving the pitch-related signals which are provided in response to the user manipulating the input device along the second axis which is perpendicular to the first axis.

16. The method of claim 14 wherein:

step (A) comprises receiving the rhythm-related signals which are provided in response to the user manipulating a handle of a joystick along the first axis; and

step (B) comprises receiving the pitch-related signals which are provided in response to the user manipulating the handle of the joystick along the second axis.
