This is an XDJ-700 refusing a stick that worked fine at home. Left column is what the player tells you. Right column is what we do about it, before you ever leave the flat.
The same stick the deck reads is a pocket player on the way there. Headphones into the jack, four buttons, one screen. No phone, no laptop, nothing to unlock.
Title, artist, album, BPM, key, rating — the same fields the deck puts on its own display, on a screen in your pocket. The waveform is the one already written into the file, not a re-analysis, so what you see here is what the CDJ will draw.
Playlist, artist, album, track, genre, BPM, key, rating, colour, label, remixer, year, folder. This is not a tree we invented — it is the one rekordbox writes and the deck reads, with the same names in the same order.
Drill down exactly as you would in the booth. The selected row inverts, the count sits on the right, the scrollbar tells you how much is left. What you learn on the train you already know at 02:00.
The tree is not ours. It is the one rekordbox writes and the deck reads — playlist, artist, album, track, genre, BPM, key, rating, colour, label, remixer, year, folder. What you scroll through on the train is what you will scroll through in the booth, in the same order, under the same names.
DJs kept hitting the same wall, so we went and found out why. We pulled apart how Rekordbox writes a library and how Pioneer’s players read one — the database, the analysis files, the tag fields the firmware actually trusts. The gap between those two is where your set dies at 02:00.
Dyapason is what closes the gap. Not a converter, not a plugin, not a subscription: one pass over your library that re-aligns every file to what the deck expects, so the deck never has to guess. It runs after Rekordbox, on what Rekordbox left behind.
Desktop software for macOS. Point it at a drive, pick the deck it is going into, press Prepare. It reports every file it touched and what it changed.
Everything the Manager does, carried in your pocket — plus the two things a plain stick can never do.
The whole pass, from a broken folder to a key the CDJ reads. No cuts.
The video is hosted on YouTube. Nothing is requested from them until you press play.
Both panels below are the same markup with one token set swapped — the test every new component has to pass. This is the live interface, not a screenshot of it.
The prototype is standard components, wired and programmed by us. Nothing here is a rendering. We would rather show you the parts list than a spec sheet we have not measured.
If you play on something that is not on this list, put it in the form. That is how the list grows — and how we decide what to buy next for the bench.

I kept hitting the same failures in the booth and got tired of waiting for someone else to fix them. Party time is too precious to lose to a file format. So I took the problem apart and built the thing that fixes it.
There is a second reason. The pocket player of the 2000s was a good idea, and it never should have gone away — least of all for the people who carry a whole set around with them. So the key plays too.
Tell us you want one and what it has to do. You will be first to hear when the series opens, and first to get the demo build of the Manager.
