Pixitracker

If even Kaossilator strikes you as staid, Pixitracker will strum your idiosyncratic itch. The oddball setup has you select a pixel-art icon, choose a note and place it on a sequencer grid. Lay enough notes down and you’ll have a tune – and if you need visual accompaniment, tap the telly button to watch Space Invaders bob around atop an audio waveform representing your musical genius.
