Instruments, avatars & credits

How the built-in instruments are made, why we chose them, and the sources behind every sampled sound. Every instrument is free for everyone — the library is built to a quality floor, not padded for a count.

A composition is only as good as the sounds it can reach for. Our goal is a built-in library that is comprehensive enough to finish a real, publishable track across the genres people actually make — house and EDM, trap and hip-hop, lo-fi, pop, ambient, rock — without ever asking you to pay for a sound. We optimise for a quality floor over a big number: a smaller set of instruments that all hold up beats a long list where half are unusable.

Three ways a sound is made

Behind the picker, an instrument is produced by one of three engines. They trade realism against flexibility, and the library uses each where it wins.

• Synth recipes — built in-house with Tone.js oscillators, envelopes, and filters. Fully synthetic, tiny, and tweakable: the leads, pads, plucks, bells, sub basses, the EDM/club synths, and the synth drum kit. These cost nothing to ship and respond instantly.
• Sampled packs — real recorded instruments, mapped across the keyboard with velocity layers and (for sustained sounds) loop points. This is where acoustic realism comes from: the pianos, electric pianos, mallets, saxophone, acoustic drum kit, and the choir.
• Custom patches — your own synth designs via the patch editor, so the library is a starting point, not a ceiling.

Sampled instruments sound real but are heavier and fixed; synth recipes are light and endlessly editable but synthetic. Most finished tracks mix both — a sampled piano or choir for the human element, synths for the energy and the low end.

Sound credits & licenses

Every sampled sound in the library comes from a source we are allowed to use commercially and redistribute — public-domain (CC0) or attribution (CC-BY) libraries, plus sounds we make ourselves. We never ship samples under non-commercial or no-redistribution terms. The CC-BY sources below require visible credit, and this is it — with our thanks to the people who recorded and shared them.

Made in-house

The synth instruments — leads, pads, plucks, bells, basses, and the EDM/club synths — plus the 808 and 909 drum kits and the synth percussion are produced entirely in-house with Tone.js recipes and offline DSP renders. No third-party samples.

Public domain (CC0)

These need no attribution, but credit is due all the same:
