Diyokee

A work in progress, DJ mixing webapp with streaming support, where the UI runs on your browser.

^{*You will notice that while loading some tracks the UI freezes. This has been greatly improved in version 2025.11.11}

Basic usage

• To load a track into a player, drag & drop the track or select the track and click the button. You can also use Shift+Ctrl+A or Shift+Ctrl+B keys on your keyboard to load a track into the A or B player, respectively.
• Click the button to start playing.
• Click the button to stop playback and move to the beginning of the track.
• Click the button to define a cue point. At this moment, only one cue point can be defined, and it will always snap to the nearest beat marker.
• Click the button to jump to the cue point. Leave the button pressed to temporarily play the track from the cue point.
• Click the button to sync the track to the other player
• Use the fader to change the volume.
• Use the fader to change the tempo (BPM).
• Use the Hi/Mid/Low knobs to change the track's equalization.
  Right-click over the Eq control to display a menu with several presets from popular mixing consoles.
• Use the fader between the two players to cross-fade between them.
• Faders and knobs can be used by clicking and dragging or by moving the mouse over them and using the scroll wheel.
• Use the and buttons under the SYNC section to perform small tempo adjustments.
• You can click and drag over both waveforms (synced and full) to change the playback position.
• Search for files in the textbox at the bottom of the files list. The search is recursive.
• Double-click a track in the files list to open the Track Properties dialog.
• Use the Jump and Cue buttons to switch between Loop/Jump and Cue tabs.
• Drag the synced waveform to scratch. Touch and release behavior is under Settings > Playback.
• In Track Properties, the Grid row edits a track's beat grid:
  • Edit - drag any beat line onto the audio it belongs on. Hover a beat and click + to pin it as a reference; nothing before a reference can move.
  • Auto - measures the track and corrects the grid for you, including the BPM if that was the error. It leaves the track alone when it cannot follow it.
  • Reset - undo every grid change.
• Since 2025/11/19 Diyokee supports MIDI controllers. Click the Settings button and scroll down to the MIDI section to select the MIDI device and create a profile for your controller.

What's new since 2026-04-14

• Scratching - drag the synced waveform. Vinyl or bend on touch, inertia or brake on release.
• Flexible beat grid - a track can now hold more than one tempo, so a track that drifts can be gridded end to end. Playback follows the grid, so it stays on the beat.
• Automatic gridding - one button corrects the grid by measuring the track rather than by eye.
• Live audio matrix - output routing changes apply immediately instead of needing a restart.
• Dropbox as a media provider.
• Measure lines on both waveforms, with a toggle for each.
• Settings dialog reorganized into categories.
• VU meters can show only the level being played, rather than that plus the track's own.
• VU beat indicator now follows the track's downbeat instead of the start of the track.
• Track Properties edits no longer reach a loaded deck until you press Save.
• Fixes: searching from a provider's root folder, cue/jump/beat-snap on a paused deck, unavailable drives in the folder browser, ARM Linux detection, and a busy indicator while a folder is being analyzed.

Notable missing features and known bugs

• Pitch/key adjustments don't seem to work on platforms other than Windows
• Accessing shared folders from Linux/macOS appears to be broken - you can still manually type/paste the folder path, but the file browser is lacking support to detect such sources
• A fancy screen for remote connections to the stream
• The settings dialog does not yet support streaming configuration
• Searching is quite limited and a bit buggy
• State preservation is only partially implemented and the way it works sucks
• Making changes to the MIDI profiles or changing the MIDI controller requires restarting the application
• ...and probably many more

Is there anyone insterested in this? Hello!? Anyone?

Footnotes

1. Before running the program, open a Terminal and change to the directory where you unzipped the file (usually ~/Downloads/diyokee-osx-x64).
   Next, run the script: ./pre-run.sh.
   Now, you can launch the app by double-clicking the Diyokee-server file in the Finder or by running ./Diyokee-server from the Terminal. ↩ ↩²
