Dynamic navigation object for a step-sequencer

A method of operating a UI for controlling a virtual musical instrument implemented on a display, the method comprising:

• receiving an input corresponding to a selection of a dynamic navigation object of a plurality of dynamic navigation objects configured on the display, the display including a cell matrix displayed in a predefined area, the cell matrix including one or more arrays of cells, each cell within the cell matrix arranged in a sequential arrangement within its corresponding array of cells, each array of the cell matrix assigned to audio sample data stored in a computer-readable medium that, in response to being triggered, causes the audio sample data to output corresponding audio, and each cell within its particular array of the cell matrix, in response to being selected for playback and upon being triggered to begin playback, causes the audio sample data corresponding to the cell's particular array to be played,
• wherein the plurality of dynamic navigation objects includes a first miniaturized representation of a first portion of the matrix of user-selectable cells and a second miniaturized representation of a second portion of the matrix of user selectable cells;
• displaying the first portion of the cell matrix in response to the first miniaturized representation being selected, such that the first portion of the cell matrix is visible in the predefined area and the second portion of the cell matrix is not visible in the predefined area;
• and
• displaying the second portion of the cell matrix in response to the second miniaturized representation being selected, such that the second portion of the cell matrix is visible in the predefined area and the first portion of the cell matrix is not visible in the predefined area.

A system comprising:

• one or more processors;
• and
• one or more non-transitory storage mediums containing instructions that cause the one or more processors to perform operations including:
• receiving an input corresponding to a selection of a dynamic navigation object of a plurality of dynamic navigation objects configured on the display, the display including a cell matrix displayed in a predefined area, the cell matrix including one or more arrays of cells, each cell within the cell matrix arranged in a sequential arrangement within its corresponding array of cells, each array of the cell matrix assigned to audio sample data stored in a computer-readable medium that, in response to being triggered, causes the audio sample data to output corresponding audio, and each cell within its particular array of the cell matrix, in response to being selected for playback and upon being triggered to begin playback, causes the audio sample data corresponding to the cell's particular array to be played,
• wherein the plurality of dynamic navigation objects includes a first miniaturized representation of a first portion of the matrix of user-selectable cells and a second miniaturized representation of a second portion of the matrix of user selectable cells;
• displaying the first portion of the cell matrix in response to the first miniaturized representation being selected, such that the first portion of the cell matrix is visible in the predefined area and the second portion of the cell matrix is not visible in the predefined area;
• and
• displaying the second portion of the cell matrix in response to the second miniaturized representation being selected, such that the second portion of the cell matrix is visible in the predefined area and the first portion of the cell matrix is not visible in the predefined area.

A computer-program product tangibly embodied in a machine-readable non-transitory storage medium including instructions to cause a processor to perform operations including:

• receive an input corresponding to a selection of a dynamic navigation object of a plurality of dynamic navigation objects configured on the display, the display including a cell matrix displayed in a predefined area, the cell matrix including one or more arrays of cells, each cell within the cell matrix arranged in a sequential arrangement within its corresponding array of cells, each array of the cell matrix assigned to audio sample data stored in a computer-readable medium that, in response to being triggered, causes the audio sample data to output corresponding audio, and each cell within its particular array of the cell matrix, in response to being selected for playback and upon being triggered to begin playback, causes the audio sample data corresponding to the cell's particular array to be played,
• wherein the plurality of dynamic navigation objects includes a first miniaturized representation of a first portion of the matrix of user-selectable cells and a second miniaturized representation of a second portion of the matrix of user selectable cells;
• display the first portion of the cell matrix in response to the first miniaturized representation being selected, such that the first portion of the cell matrix is visible in the predefined area and the second portion of the cell matrix is not visible in the predefined area;
• and
• display the second portion of the cell matrix in response to the second miniaturized representation being selected, such that the second portion of the cell matrix is visible in the predefined area and the first portion of the cell matrix is not visible in the predefined area.
