How we make things
Last updated 11 November 2026.
sOURnd makes tools for people who make music. This page says what we will and will not do, so you can hold us to it.
AI should enable people, never replace them
AI should always enable creators, musicians and producers, and never replace them.
Every sOURnd engine is an effect on audio you supply or an instrument you play. We use AI to build tools: engine code, settings, the pictures on this site. We never use it to make music, and nothing here writes, plays or sings for you. The music is yours.
No one-for-one copies
Nothing on this site is a one-for-one copy of someone else's product.
Effects. Where we have studied or sampled equipment or software, we blend several sources into a sound of our own. We do not reproduce any single one of them.
Synths. Every synth runs on one voice engine we wrote ourselves, first for Box Of Synths during its beta. Each is voiced after the character of a classic instrument: how its filter, envelopes and drift behave. We use no samples, code or circuit designs from the original.
There is one exception. Where a piece of equipment is discontinued and no longer made, we may reproduce what it did more closely, so that its sound stays within reach of people who could never find or afford one.
We describe every engine by how it sounds and what it does. We do not use another maker's name, product name or trade mark to sell it.
Not for tools that generate music
We do not allow our engines, our services or anything we host to be used to build, train, test or supply data to tools that generate music, audio or performances, or to be shipped inside one. This is part of our terms and our licence.
Using an AI assistant to help you build a plugin or a game with our engines is welcome. That is a person making a tool, which is what sOURnd is for.
If we get it wrong
If you think something here falls short of this page, tell us. We read every message and we will put it right.
Kind regards,
