- Worth noticing
- A fixed shuffle seed repeats the same input; each value maps to a pitch, with a separate voice for the second sort in a battle.
Field notes
The controls expose a repeatable shuffle seed, element count, speed, and separate settings for look, data, sound, and color. The feature table lists three free color themes versus ten for Pro; it also says Pro removes the watermark from videos. The video interface asks users to keep the screen open while a video is being made.
