Abstract

An automatic accompaniment generating apparatus capable of generating automatic accompaniment as intended by a user. In an arpeggio sounding data generation mode, when key depression tones are input by a user'"'"'s key depression operation after arpeggio pattern data is selected and a loop count is set to a value of “1” by the user, the sounding of the key depression tones is started, and the generation of a sounding data list is started based on the tone pitches of the key depression tones and sounding pattern data included in the selected arpeggio pattern data. In the case of the loop count being set to “1”, the reproduction of the sounding data list is completed at the end of one bar, and thereafter only the key depression tones are sounded until a key release operation is performed by the user.

Claims

1. An automatic accompaniment generating apparatus comprising:

a supply unit adapted to supply automatic accompaniment pattern data;

an input unit adapted to input at least one piece of note information including tone pitch information;

a generation unit adapted to generate automatic accompaniment data based on the note information input by said input unit and the automatic accompaniment pattern data supplied by said supply unit; and

an acquisition unit adapted to acquire number-of-times information that indicates a number of times the supplied automatic accompaniment pattern data is to be repeatedly used by said generation unit to generate the automatic accompaniment data,

wherein said generation unit repeatedly uses the supplied automatic accompaniment pattern data the number of times indicated by the number-of-times information acquired by said acquisition unit, to thereby generate the automatic accompaniment data.

2. The automatic accompaniment generating apparatus according to claim 1, wherein said generation unit starts generating the automatic accompaniment data in response to the at least one piece of note information being input, and stops generating the automatic accompaniment data after the automatic accompaniment data is repeatedly generated the number of times indicated by the number-of-times information.

3. The automatic accompaniment generating apparatus according to claim 1, wherein non-specified information indicating that the number of times the supplied automatic accompaniment pattern data can be repeatedly used is not specified can be set as the number-of-times information, and

wherein when the non-specified information is set, the supplied automatic accompaniment pattern data is repeatedly used until the at least one piece of note information is no longer input.

4. The automatic accompaniment generating apparatus according to claim 1, wherein the number-of-times information is set by a user.

5. The automatic accompaniment generating apparatus according to claim 1, wherein the automatic accompaniment pattern data is arpeggio pattern data.

6. An automatic accompaniment generating method comprising:

a supply step of supplying automatic accompaniment pattern data;

a generation step of generating automatic accompaniment data based on at least one piece of input note information including tone pitch information and the automatic accompaniment pattern data supplied by said supply step; and

an acquisition step of acquiring number-of-times information that indicates a number of times the supplied automatic accompaniment pattern data is to be repeatedly used by said generation step to generate the automatic accompaniment data,

wherein said generation step repeatedly uses the supplied automatic accompaniment pattern data the number of times indicated by the number-of-times information acquired by said acquisition step, to thereby generate the automatic accompaniment data.

7. The automatic accompaniment generating method according to claim 6, wherein said generation step starts generating the automatic accompaniment data in response to the at least one piece of note information being input, and stops generating the automatic accompaniment data after the automatic accompaniment data is repeatedly generated the number of times indicated by the number-of-times information.

8. The automatic accompaniment generating method according to claim 6, wherein non-specified information indicating that the number of times the supplied automatic accompaniment pattern data can be repeatedly used is not specified can be set as the number-of-times information, and

wherein when the non-specified information is set, the supplied automatic accompaniment pattern data is repeatedly used until the at least one piece of note information is no longer input.

9. The automatic accompaniment generating method according to claim 6, wherein the number-of-times information is set by a user.

10. The automatic accompaniment generating method according to claim 6, wherein the automatic accompaniment pattern data is arpeggio pattern data.
