v0.9.6

⚠ Superseded within the hour: v0.9.6's "Install on deck" crashed on start (job() got an unexpected keyword argument 'flac'). Use v0.9.7 — same content, that bug fixed.

XDJ Mod Studio v0.9.6 — Windows parity, key-shift freeze fix, live phase meter, hot-cue tap paging, FLAC opt-out, UPD presets.

Open-source mods for the Pioneer DJ XDJ-700, loaded into the deck's memory
over USB. Nothing is flashed: switch the deck off and on and it is stock
again. You need your own official XDJ-700 v1.15 update file (from Pioneer
DJ's support site); the app checks it and builds everything from it.

Mac app (Apple Silicon, macOS 14+): download XDJ-Mod-Studio.zip, right-click → Open on first launch.
Windows: download XDJ-Mod-Studio-Windows.zip and unzip it anywhere.

What changed in 0.9.6

  • Windows gets everything the Mac had. The 0.9.5 Windows app was built
    from a stale snapshot of the source: the permanent-file builder with its
    extras, the phase meter module, the PERFORM-pad font fix and several
    deck-side fixes never reached it. The Windows reports of "UPD creation
    stops after 2 minutes", "centre colour module not built" and "PERFORM
    pads install failed (AssertionError 2802)" all trace back to that —
    0.9.6 ships one source for both platforms.
  • Key shift freeze fixed (tester: MT off → key shift → MT on froze the
    deck): the KEY SHIFT tab is inert while MASTER TEMPO is off, and any
    MASTER TEMPO change resets the key to 0.
  • 8 hot cues: tap works too. Paging was swipe-only; three testers
    naturally tapped the HOT CUE tab. Tap and swipe both page A–C / D–F / G–H.
  • Phase meter: reads the time digits' own position source. The word it
    used first freezes on a real deck (the beats never scrolled); it now
    reads the live one, verified in the emulator against a tick-by-tick model.
  • FLAC & Opus can be left out of an install — it was 10 of the 15–20
    minutes. Untick it on the Mods page and add it later.
  • Permanent (UPD) file presets — "Phase meter only" and "Waveform
    colours only" one-click presets next to the tick boxes.
  • If colours or the phase meter look gone after a trip through MY SETTINGS:
    check [WAVEFORM] is not BLUE and [MODS] is ON in that menu — those rows
    switch them off.

Tested on a real deck

  • RGB and 3-band waveforms — the overview strip and the big centre
    waveform, from the colour data rekordbox already exports.
  • Live key shift — PERFORM › KEY SHIFT moves the key up or down while
    the track plays (MASTER TEMPO on); tempo stays put and the panel shows
    the track's real key.
  • Live themes — step through colour themes from MY SETTINGS; OFF
    brings back the exact stock look.
  • Live stems — mute vocals / drums / bass / other from PERFORM ›
    STEMS. A mute is heard after about 30 seconds.
  • Beat jump pads — PERFORM › BEAT JUMP: tap to jump, swipe the row for
    1 up to 64 beats.
  • The permanent (UPD) file — one tester flashed it on a real player:
    version 1.16 ran with the RGB overview, beat jump, key shift, stems and
    hot cue paging after power-off.

Working in the emulator, not yet tested on a deck

These run on the deck's own firmware in the emulator, so they should work
on a real deck too, but nobody has tried them on one yet:

  • Faster stem mute (beta) — rewrites the audio the deck has already
    buffered, so a mute is heard in under a second in the emulator.
  • Phase meter with the live position source — this deck's beats and
    downbeats above the waveform (the 0.9.5 build's beats stood still on a
    deck; this one reads the clock's own word).
  • Vinyl brake length — MY SETTINGS › [VINYL BRAKE], 0.5× to 15×.
  • 8 hot cues — A–H, in pages of three (swipe or tap the tab).
  • FLAC and Opus playback.

Known issues

  • The emulator's audio stutters (the emulated audio chip runs slower than
    real time). Browsing, loading and the screens are fine.
  • Stems need PWV6/PWV7 waveform data in the track's .EXT (rekordbox's
    Track Builder can add it); without it the STEMS tab shows the mix only.

Safety

Everything lives in the deck's memory; a power-cycle always returns it to
stock. The optional Permanent (UPD) tab builds a firmware file you
would flash yourself. That one can brick a deck, and the app says so
before it builds anything.

Open source

All of it — the Mac app, the emulator, every mod and the tools that build
them — is on GitHub under the MIT licence. Pioneer DJ's firmware is not
included; you add your own copy.
