ToneMatrix is a free music synthesizer and an entertaining time waster that lets you create your own audio sequences online by selecting steps on a 16×16 matrix. Simply select steps with your mouse across the whole matrix. The sound plays from left to right, based on your selected sequence of steps. Click once to select, click again to deselect. Press SPACE key, to clear all.
To save your sequence simply right-click on the matrix, click “copy” and save the sequence on your computer. To hear it next time simply paste it on to the matrix.
