- Worth noticing
- The studio includes undo, whole-stroke erasing, tempo and scale changes, plus PNG artwork and WAV audio export.
Field notes
The studio treats the canvas as both a score and an instrument: horizontal movement supplies time, vertical placement changes pitch, and each color has its own sound. The page says projects remain in the current browser and can be saved for later editing; PNG artwork and WAV audio are listed as export options. Android and iOS versions are presented as plans rather than available apps.
