Work in the Live Loops grid in GarageBand for iPhone
The Live Loops grid is where you record, play, and edit your musical ideas. The grid consists of cells, which can be empty or filled. Cells can contain Touch Instrument recordings, loops, or audio files. You can start and stop individual cells freely, or start multiple selected cells in sync.
In the grid, cells are arranged in rows and columns. Each row uses the same Touch Instrument, similar to a track in Tracks view, and only one cell in a row can play at a time. Cells in a column can have different lengths (durations). You can play back cells in a column individually, or start playback for all cells in the column simultaneously, using the trigger at the bottom of the column.
Playing cells and other actions in the grid follow the current Time Snap setting. Time Snap ensures that your changes start at musically meaningful points in time (beats or bars), so they are in sync with other cells. You can set the Time Snap value and change it while you are working in the grid.
