- Worth noticing
- The page says the instrument runs on the user's own machine; it gives no date for macOS or acoustic-instrument support.
Field notes
The described session starts with a player connecting a MIDI keyboard to a Windows PC and playing a fragment, chord, or even a mistake they like. Duetra is supposed to follow the player's rhythm and answer when space opens up; the page says it runs locally rather than in the cloud. Acoustic-instrument support and a macOS version are described as future work, with no dates given.
