Every sound that ships inside Tremor is either made in-house or licensed from the people who made it. These are the people.
The two "Tremor DJ" drops that open a set and ID the station, Tremor Hits and You're Listening, were voiced and produced by Brandon at DJ Drops 24/7 in Florida, and are bundled with his written clearance. If you need drops of your own, this is where a working DJ goes.
The three scratch one-shots Tremor's platter cuts, Ah, Ah Yeah and Fresh, come from the DJ Scratch Essentials: Flow in Motion pack by Primal Creators in Arlington, Texas, and ship credited to Primal Creators under their embedded-use authorization. The full pack has far more material for anyone building routines.
The kicks, hats, claps and 808 that the instrument rack plays, by hand or by your AI, are curated from Charlie Mac's Drums Pleaze pack, licensed through AudioSparx for embedded use, worldwide and in perpetuity.
The third drop, Locked In, and the robot station IDs on the instrument rack are fully synthesized: text-to-speech from the open Kokoro model (Apache 2.0) and our own signal processing. No recorded voice, no third-party samples. Every other sound in Tremor, from the scratch physics to the drum machine, is generated by the engine itself.
Tremor's stem separation runs on-device with a model derived from the open Demucs family; beat tracking, key detection and music classification are our own models trained and run locally. The Mac and iOS apps use a handful of open-source packages, each under its own license, listed inside the app under Settings › About.
None of these partners receive anything from your use of Tremor. Their work ships inside the app; your music, your mixes and your AI sessions stay on your device.
If you make sounds DJs need, drops, kits, scratch samples, and want them in front of Tremor's users as bundled or add-on content, write to support@mindarray.io. Clear licensing, credit on this page, and a real audience of working DJs.
