Software you buy once, that keeps working.

Music production and live-performance software for desktop and mobile — the kind of tool you install once and still trust on a stage five years later. Our first product is in development. It will be announced here when it is ready, and not before.

These are not aspirations. Each one is built into how the software and the licence server are designed, and the terms of sale hold us to them.

You own what you buy

One purchase covers every platform we support, for as long as that version lives. No subscription — not now, and not later.

It works offline, forever

Nothing checks your licence while you work. No phone-home, no activation server in the runtime path, no DRM. If Synthtropy ever closes its doors, every installation keeps running, and our terms commit us to issuing licences that unlock anywhere before that happens.

We do not track you

No third-party analytics, no advertising pixels, no conversion trackers, and nothing stored on your device by this website. It costs us advertising efficiency and we consider that a fair price.

Your data stays yours

An account exists for one reason: to move your licence between your own devices. Delete it and it is deleted — we do not keep a shadow copy to remember you by.

Write to contact@synthtropy.com for anything at all — support, invoices, press, or a data request under the GDPR.
