Summary

The site is now a small playful DAW. The homepage is a landing page with a live 4×4 kit and mini piano. The studio is the instrument: Akai-style pads and keys, a prompt that builds a beat from original patterns, a big Record button, and an easy way to add tracks and loop a scene.

• Record opens a choice: what you play, your voice, live autotune, a voice changer (robot, radio, chipmunk, and more), or singing into an instrument in real time. Autotune and instrument mode reuse the existing pitch tracker. Voice colors are Web Audio on the live mic. The take stored on the timeline for the changer is the dry voice; the effect is what you hear while singing.
• Make a song builds drums, bass, and keys from original preset patterns (hip-hop, house, pop, jazz, lo-fi, funk, trap, rock). No paid API.
• Split a song drops the file onto its own tracks. With no server, a quick in-browser split sorts drums, bass, melody, and the rest (not a vocal isolator, 25 seconds max). For a real vocal / drums / bass / other split, point Studio at the local Demucs sidecar.
• The previous homepage DAW is still at classic.html. Import, effects, and the SEO pages stay.

Local Demucs

The static site cannot host the model. From services/ai-sidecar:

pip install -r requirements.txt
uvicorn app.main:app --host 127.0.0.1 --port 8765

Paste http://127.0.0.1:8765 into Studio’s local engine URL. The first split downloads the free htdemucs_6s weights. POST /stems and GET /stems/{job}/{name} are on the existing sidecar. Nothing here calls a paid API.

Test plan

• Landing pads and mini keys make sound; Make it opens the studio with that beat
• Studio pads and piano make sound; Loop and a scene column loop four bars
• Record → what I play arms the timeline; voice modes ask for the mic and play live
• Add a drum, keys, and audio track
• Split a short song with the engine URL empty and see four tracks
• Optional: start the sidecar and confirm a Demucs split
• Classic DAW and a hub page still load
