Questions about this entry
Short answers drawn from the linked project or page.
A playhead sweeps across the score, and each time it crosses a bar line Jev is told what is playing, what is coming next, and what just happened. Jev answers up to 11 questions in parallel, and the music changes exactly on the next bar line.
Jev chooses how loud each painting plays, mood, energy, drums and bass on or off, lead instrument, two textures from eight candidate sounds, transition type, and whose culture leads when paintings from different cultures overlap. It can also keep a choice instead of changing it.
A full 11-question bar has a median of 204 ms against a budget of about 2.5 seconds. The project reports 0 missed bars in long sessions.
The project states a cost of about $0.00004 per bar for Jev's decisions.
Gemini looks at each painting and reads its mood, the sounds it suggests, and its cultural roots. For example, The Great Wave comes back as Edo-period Japanese music with koto, taiko, and shakuhachi.
No. The repository is a showcase, the source code is private, and the project states all rights reserved.
It is a showcase rather than an installable library, with private source code. It depends on Gemini and Lyria RealTime, with a live-coded Strudel synth band as an instant fallback.
