Your music stays on your computer
Music you load from your computer is read inside your browser and never reaches our servers. BPM and key are analyzed on your own machine, and your hot cues and memory cues are saved in your browser, not in an account.
Tracks from the GPW catalog play as the same watermarked preview you hear on the site. If one fits your set, Buy on the deck opens its page. Every GPW track is exclusive and sold once, with full rights to the buyer.

Do I need to download anything?

Can I mix my own music?

Are my music files uploaded?
No. Music from your computer stays on your computer. BPM and key are analyzed inside your browser, and nothing is sent to our servers.
Does it work on a phone?
No. GPW DJ Studio needs a desktop browser and a window at least 1024 pixels wide, so open it on a computer.
Can I use a DJ controller?

Can I record my mix?
No. GPW DJ Studio has no set recording and no microphone input.
Can I mix songs from Spotify or YouTube?
No. The decks play files from your computer and previews of Ghost Producer World tracks. Streaming services are not connected.
Do GPW tracks play in full quality?
GPW tracks play as the same watermarked preview you hear on the site, never the master file. To own one, press Buy on the deck: it opens the track page. Every GPW track is exclusive, sold once with full rights.
Is it good for beginners?
Yes. Press HOW TO PLAY on the bar under the booth for a step-by-step tour: the camera moves to each control and explains what it does while you try it.
Does it have beat sync and key sync?
Yes. BEAT SYNC matches one deck to the tempo and beats of the other, and KEY SYNC shifts a deck to a compatible key. BPM and key are detected when a track loads, and MASTER TEMPO keeps the pitch steady when you change the tempo.
