Questions
and answers.

Not to listen: the catalogue of shared songs is open to everyone. To create you need a verified e-mail (a one-time code, no password): 10 generations every 24 hours, 30 once your profile is complete.

No. A free description is enough. Studio is there when you want to go into notes, chords and sounds.

HTC is tested in recent Chrome on desktop and Android. Other modern browsers should work; a large screen is best for Studio.

One Set of six projects, or one composing action in Studio (regenerate or add a part, vary a section, new takes, another Music Model). It counts only if it succeeds. Listening, editing, mixing and exporting never count.

Four interpretations of your request (Faithful, Groove-led, Harmonic & spacious, Melodic) and two HTC Extreme takes that push the idea further. Comparing them is part of the work.

House, techno, breakbeat, drum and bass, trip-hop, dub, downtempo and ambient, and mixes of them. It does not sing and does not do orchestras or live bands; it says so before composing.

The result is kept on the server and offered again (Library · Recovered); it is not charged twice.

No — it is a project: sections, parts, notes, instruments and mix, played live in your browser. You export audio when you want it.

Notes, drum steps, chords, sections, parts, instruments and their settings, automation, mix and master — and you can record notes from your keyboard or a MIDI controller. Every change is a revision.

From Export: WAV or MP3, the whole mix or stems, rendered in your browser.

In the Library of the browser you use. With an account, a private copy is also kept on the server and synchronised with your other devices.

HTC’s own synthesisers and drum machines, and sampled instruments under open licences (credited on the licences page).

The beta terms are provisional and under legal review; read them before any commercial use. Some samples require attribution, listed with the song when it applies.

No. Projects are private unless you submit a song to the curated catalogue and the team approves it. You can withdraw it at any time.

Because the catalogue is made of songs people chose to share, and every shared song tells us something. It is an invitation, never a condition: you choose which (one or more, or none), you see what becomes public first, and your prompt stays private unless you include it.

The beta is free, and we want you to experiment generously. Allowances and conditions may change as HTC grows; any change will be announced in advance and will never take away the projects you saved.

Each generation comes back 24 hours after it was made — not at midnight, and without piling up. The app shows what is left and when the next one returns. Completing your profile raises the limit at once, keeping what you already used; a substantial feedback adds 10 more, once every 24 hours.

A programme in preparation for the first people who help build HTC, separate from registering. Its benefits are still being defined and will be published before it opens; today you can only tell us you are interested, from your account.

Yes, and it is optional: you subscribe from your account preferences, every message has a one-click unsubscribe, and it is never needed for anything else — not even for the Founding Contributors programme.

Because it is a lab. The HTC you use today may be different tomorrow; the What’s new page lists what changed. Your saved projects keep the version that made them.

A technical session cookie, your requests and results, your Library copy and e-mail if you register, your feedback, and — only if you choose — a profile, your newsletter subscription or your interest in the Founding Contributors programme. No advertising trackers. See the privacy notice.

No. Name, city and country are private. Only a nickname you choose can appear, and only next to songs you decide to share.

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

There is no fixed end date yet. Functions and limits may change; we will say so in the app and on the What’s new page.
