- Children, beginners, teachers, and curious musicians
- Worth noticing
- The canvas maps horizontal position to time and vertical position to pitch, with color and program choices changing the sound.
Field notes
The instrument treats a blank canvas as a sequencer: horizontal placement establishes when a sound occurs, while vertical placement determines pitch. Users can constrain drawings to named scales, choose one to three octaves, apply quantization or swing, and add a metronome click. The page also lists touch and MIDI input plus WAV and MIDI export, making it usable both as a playful teaching surface and as a compact sketching tool.
