Abstract

A method including receiving a first set of performance data corresponding to a first plurality of MIDI-based notes in a first rhythmic order. The first plurality of MIDI-based notes may form a first arpeggio, with each of the first plurality of notes having a corresponding first performance data. The method further includes receiving input data indicating a change to the first performance data corresponding to a note in the first plurality of notes, changing the first performance data for the corresponding note using the input data, receiving a second set of performance data corresponding to a second plurality of MIDI-based notes, and applying the changed first performance data to the second performance data. Applying the first changed performance data includes editing the second set of performance data in real-time by replacing the second performance data with the changed first performance data.

Claims

1. A computer-implemented method comprising:

receiving, on a computing device, a first set of performance data corresponding to a first plurality of MIDI-based notes, wherein the first set of performance data is received in a first order;

receiving input data requesting a change to the first set of performance data;

changing the first set of performance data based on the input data;

receiving a second set of performance data corresponding to a second plurality of MIDI-based notes, wherein the second set of performance data is received in a second order; and

applying the changes made to the first set of performance data to the second set of performance data in real-time.

2. The computer-implemented method of claim 1 further comprising:

storing the changed first set of performance data in a database; and

retrieving the changed first set of performance data from the database prior to applying the changed first set of performance data to the second set of performance data.

3. The computer-implemented method of claim 1 further comprising arranging the first set of performance data in a graphical grid pattern in the order received.

4. The computer-implemented method of claim 1 wherein the first set of performance data includes a note velocity.

5. The computer-implemented method of claim 1 wherein the first set of performance data includes an identifier indicating whether a corresponding note is one of a musical note, a rest, or a note-tie.

6. The computer-implemented method of claim 1 wherein the first set of performance data includes a timing of the order received.

7. The computer-implemented method of claim 1 wherein each of the first and second sets of performance data in the graphical grid pattern is configured for real-time step editing.

8. The computer-implemented method of claim 1 wherein the second plurality of MIDI-based notes is a chord, wherein the second plurality of notes is arpeggiated based on the order and changed first set of performance data.

9. A computer-implemented system, comprising:

one or more processors; and

one or more non-transitory computer-readable storage mediums containing instructions configured to cause the one or more processors to perform operations including;

receiving, on a computing device, first set of performance data corresponding to a first plurality of MIDI-based notes, wherein the first set of performance data is received in a first order;

receiving input data requesting a change to the first set of performance data;

changing the first performance data based on the input data;

receiving second set of performance data corresponding to a second plurality of MIDI-based notes, wherein the second set of performance data received in a second order; and

applying the changes made to the first set of performance data to the second set of performance data in real-time.

10. The system of claim 9 further comprising:

storing the changed first set of performance data in a database; and

retrieving the changed first set of performance data from the database prior to applying the changed first set of performance data to the second set of performance data.

11. The system of claim 9 further comprising arranging the first set of performance data in a graphical grid pattern in the order received.

12. The system of claim 9 wherein the first set of performance data includes one or more of a velocity or an identifier, wherein the identifier indicates whether the corresponding note is one of a musical note, a rest, or a note-tie.

13. The system of claim 9 wherein each of the first set of performance data in the graphical grid pattern is configured for real-time step editing.

14. A non-transitory computer-program product, tangibly embodied in a machine-readable non-transitory storage medium, including instructions configured to cause a data processing apparatus to:

receive, on a computing device, first set of performance data corresponding to a first plurality of MIDI-based notes, wherein the first set of performance data is received in a first order;

receive input data requesting a change to the first set of performance data;

change the first set of performance data based on the input data;

receiving a second set of performance data corresponding to a second plurality of MIDI-based notes, wherein the second set of performance data is received in a second order; and

apply the changes made to the first set of performance data to the second set of performance data in real-time.

15. The computer-program product of claim 14 further comprising instructions configured to cause a data processing apparatus to:

store the changed first set of performance data in a database; and

retrieve the changed first set of performance data from the database prior to applying the changed first set of performance data to the second set of performance data.

16. The computer-program product of claim 14 further comprising instructions configured to cause a data processing apparatus to arrange the first set of performance data in a graphical grid pattern in the order received.

17. The computer-program product of claim 14 wherein the first set of performance data includes one or more of a velocity or an identifier, wherein the identifier indicates whether the corresponding note is one of a musical note, a rest, or a note-tie.

18. The computer-program product of claim 14 wherein the first set of performance data includes a timing of the order received.

19. The computer-program product of claim 14 wherein each of the first and second set of performance data in the graphical grid pattern is configured for real-time step editing.

20. The computer-program product of claim 14 wherein the second plurality of MIDI-based notes is a chord, wherein the second plurality of notes is arpeggiated based on the order and changed first set of performance data.
