in response to the third user input interacting with the second user interface element of the first plurality of user interface elements and the third user interface element of the first plurality of user interface elements:

merging two played notes, each represented by one of the second user interface element and the third user interface element; and

replacing display of the second user interface element and the third user interface element with a single additional user interface element representing the merged two played notes.

14. An electronic device, comprising:

a display;

one or more processors; and

memory storing one or more programs for execution by the one or more processors, the one or more programs including instructions for:

displaying a graphical user interface for a step sequencer in a digital audio workstation, wherein:

the graphical user interface for the step sequencer includes a plurality of user interface elements,

the plurality of user interface elements corresponds to a portion of a roll for an audio composition,

each user interface element in the plurality of user interface elements represents a respective time interval for a note,

the plurality of user interface elements includes a first subset of the plurality of user interface elements representing played notes for the corresponding respective time interval and a second subset of the plurality of user interface elements representing rests for the corresponding respective time interval;

the plurality of user interface elements correspond to toggleable buttons arranged in an array comprising a plurality of rows and columns, each toggleable button being activated or inactivated by a user, wherein a row of the plurality of rows corresponds to a sequence of user interface elements;

receiving a user input interacting with a first user interface element of the first subset of the plurality of user interface elements;

in response to the user input interacting with the first user interface element of the first subset of the plurality of user interface elements:

splitting a played note represented by the first user interface element into two or more played notes;

replacing display of the first user interface element with two or more additional user interface elements, each of the two or more additional user interface elements representing a respective one of the two or more played notes; and

providing the audio composition for playback by a speaker.

15. The electronic device of claim 14 , wherein an adjacent played note in the first plurality of user interface elements is not split into two or more notes in response to the user input.

16. The electronic device of claim 14 , wherein:

the plurality of user interface elements includes a plurality of sequences of user interface elements, wherein a respective row of the plurality of rows corresponds to a respective sequence of the plurality of sequences of user interface elements,

each sequence in the plurality of sequences of user interface elements corresponds to a distinct sound made by an instrument.

17. The electronic device of claim 14 , the one or more programs further including instructions for:

receiving a second user input interacting with a respective one of the two or more additional user interface elements representing a respective one of the two or more played notes,
