Case study · Feedback Loop
Safe feedback loops for unfinished music.
Kyvelon designed and shipped Feedback Loop — a private product where musicians share demos, collect timestamped feedback, and improve version by version without public feeds or stolen ideas.
Full cube implementation: software, surface, automation, and strategy — live at feedbackloop.studio.
The brief
Creators needed feedback without exposure.
Unfinished tracks cannot live on social feeds. Musicians needed a calm system: invite-only listening, comments locked to the timeline, version history, and AI analysis that never trains on their work. Privacy was not a feature — it was the volume of the cube.
Before
Public feeds · likes · leaked demos
After
Private pools · timestamped notes · owned IP
δομή · Structure
Define the cube before cutting faces.
Goals: private collaboration and measurable improvement. Users: producers, songwriters, trusted circles. Constraints: no public discovery, revokeable access, credits that reward giving feedback, GDPR-grade control over audio. Only faces that served that volume made the cut.
The product system
Every edge designed — from waveform to credit.
The product is the cube made concrete: timeline feedback, version history, private pools, and AI analysis that stays outside the artist's IP.
Timestamped comments
Pin notes to the exact moment in the track — no more “around 1:30” guesswork.
