Randomize grid every repeats.

This is a sequencer. A timer proceeds through the grid, playing a note for each enabled square in a column when its time arrives. Click on squares to enable them, or drag your mouse around inside the grid. Alternatively, the "Random" button will set a random pattern. Click the "Start" button to start the sequencer. All controls can be changed while the sequencer is playing or stopped.
