Field notes
Controls are grouped as Make, Drive, and Break: Generate writes in a selected key and scale, Mutate changes one or two steps, and Taste is said to learn from riffs the user keeps. The second voice can send its own riff as MIDI, while exports include MIDI, a seamless four-bar loop, or the screech alone. The page labels the instrument in development; its €39 launch purchase is not yet open.
