A beta to make
with musicians.

The HTC you discover today may already be different in two hours, tomorrow or next week. That is not a promise of an update every two hours — it is how the lab works. What can change: the quality of the compositions, new Music Models and GenreDNA, instruments, patches and expression, Studio, the interface and its accessibility, the way you create, and how people share and, one day, work together.

What never changes behind your back: your projects. Each one keeps the model, the sounds and the versions that made it. A new model is a new version you can choose to try, never a silent rewrite of music you saved. Everything that changed is listed, version by version, on What’s new — come back and see.

Most AI music tools hand you a finished audio file. HTC does something else: from one idea it composes six structured interpretations — real projects you can explore, listen to, change and develop. AI is a collaborator inside a studio, not a vending machine. The goal is music you develop, not music you only download.

Three relationships with the same lab — not three apps, and not plans for sale. A separate Founding Contributor programme is in preparation; today you can only tell us you are interested, from your account.

• Listening is free, with no account. The catalogue of songs people chose to share and the team approved is open to everyone.
• 10 generations every 24 hours with your e-mail (HTC Explorer), 30 with a complete profile (HTC Member). A generation is one Set of six projects, or one composing action in Studio (a new part, a regenerated part, new takes…). It counts only when it succeeds, and each one comes back 24 hours after it was made — it does not pile up.
• Feedback can add 10 more: a substantial, new message — positive or critical alike — from a verified e-mail, at most once every 24 hours. Opening more accounts gives nothing.
• Listening, editing, mixing and exporting never count. The allowance and the next renewal are always shown in the app.

We want people to experiment generously during this first phase. As HTC grows, allowances, limits and conditions of access may change. When they do, the change will be versioned, announced in advance and explained — and it will never take away access to the projects you already saved. There is no payment in the beta, and no promise about future plans or prices.

Use HTC as you would: make music, open it in Studio, export it, come back to see what changed. Then tell us — from the tab on this page, from the app bar, or from Studio on a specific song (with the exact position and, if you want, the revision attached). Bugs are welcome; musical observations even more: groove, voicing, form, sound, mix. Critical feedback is the most useful kind.

The HTC team reads every message. When you comment on someone else’s published song, its artist reads it too — the app tells you before you send.

After a Set, HTC invites you to share at least one of the six with the beta catalogue — the one you would play to a friend, or more than one. It is an invitation, never a condition: your projects are private, nothing is published automatically, and the Library is never public by default.

Before sending, you see exactly what becomes public: the song (one frozen revision), its title, your nickname only if you choose it, and the credits of its sounds. Your e-mail, your name and your Library never are; your prompt only if you include it. The team listens first, only songs whose sounds may be shared can be published, and you can withdraw yours at any time. Publishing shows a song — it does not hand over its samples or presets.

We want to offer the first people who help build HTC a real chance to take part — and, when new conditions or plans arrive, treatment reserved to founding contributors. What that could include is still being designed: a recognisable badge, founding status, early access to new features, more favourable generation conditions than future ordinary users, reserved plans or benefits if and when they exist, voluntary public recognition, time with the team. None of this is active or promised yet: benefits, duration and conditions will be written down and published before the programme opens.

What will count is authentic contribution: useful musical or functional feedback, reproducible bugs, suggestions, thoughtful experimentation, voluntarily shared music. Not positive reviews, not volume, and no hidden ranking. The newsletter is not a requirement. If you are interested, say so in your account preferences: it records your interest, nothing more.

The newest Music Model, some instruments and parts of the interface change often. Projects keep the model version that made them, so an update never rewrites your music; if something breaks, your feedback helps us find it.

We keep what HTC needs to work: a technical session cookie, your requests and results (so you can recover them), your e-mail if you register, your feedback. A profile, the newsletter and the Founding Contributors interest are separate choices you can change at any time. No advertising trackers. Details are in the privacy notice and the beta terms — both provisional, under legal review.
