Roland DJ-505


The Roland DJ-505 is an all-in-one USB MIDI controller with an integrated audio interface. It has controls for 2 decks that can be toggled between decks to play with 4 decks. It also features a TR-S step sequencer with sounds from the TR-808 and the TR-909 drum machines (TR-606 and TR-707 are available via firmware update).


You can download the latest Windows & MacOS drivers and firmware from the manufacturer's website. Since the DJ-505 is a USB class compliant MIDI and audio device, the device is plug-and-play on Linux.

Controller Mapping

A mapping has been added to Mixxx prior to the 2.3.0 release.

Audio Channels

The mapping relies on the following channel assignments (for line/phono input support, applying effects to the TR-S output, etc.):

Channels Assigned to
1-2 Master
2-3 Headphones
Channels Assigned to
1-2 (CH 1 Line/Phono) Vinyl Control 1
3-4 (CH 2 Line/Phono) Vinyl Control 2
5-6 (Mix) Record/Broadcast
7-8 (TR-S output) Auxiliary 1

Note: You should assign the Vinyl Control input channels even if you do not intend to use timecode vinyl. These channel assignments are also needed to make the CH 1/2 PC/LINE/PHONO switches work (i. e. passing through line or phono input to the left/right deck).


A schematic drawing with the control numbers that are used here can be found on the specified page in the Owner's Manual.

Performance Pads

You can use the Pad Mode Select buttons to select a mode for the performance pads.

Control Mode LED Color
[HOT CUE] button Hot Cue Mode White
[SHIFT] + [HOT CUE] button Cue Loop Mode Blue
[ROLL] button Roll Mode Light blue
[ROLL] button (press twice) Loop Mode Green
[TR] button TR Mode Red
[SHIFT] + [TR] button Pattern Mode Green
[TR] button (press twice) TR Velocity Mode Orange
[SAMPLER] button Sampler Mode Magenta
[SHIFT] + [SAMPLER] button Velocity Sampler Mode Purple
[SAMPLER] button (press twice) Pitch Play Mode Green

Most pad modes are similar to those found when used with Serato. A notable exception is the Loop Mode, which replaces the Serato's Saved Loop Mode. In this mapping, the Loop Mode is similar to the Roll mode, but sets a non-rolling beatloop instead.

  • Hot Cue Mode: Press a pad that is unlit to assign a hot cue point to it. If a pad is lit, press it to start playback from the hot cue location. Hold [SHIFT] and a pad to clear the hot cue. Use the PARAMETER BUTTONS for moving the beatgrid left/right.
  • Cue Loop Mode: When the deck is playing and a pad that is lit is pressed, auto loop will start from the location of the hot cue point that is assigned to the pad. If the pad is not lit, a hot cue is specified at the current location and auto loop starts immediately.
  • Roll Mode: While holding down a performane pad, a rolling loop plays with the beatlength that is assigned to the pad. The pad that creates a roll of 4 beats length is illuminated. Each pad to the right doubles the length, left halves it. You can use the PARAMETER buttons to cycle through four sets, as described in the Owner's Manual.
  • TR/Pattern/TR Velocity Modes: These modes are hardcoded in the device, so they work exactly as described in the Owner's Manual.
  • Sampler/Velocity Sampler Play Modes: Press a pad that is unlit to load the track under the cursor into the sample slot assigned to the pad. If the pad is lit, the sample in the slot is played. In Velocity Sampler Mode, pressing the pad stronger results in a louder sample playback volume. When holding [SHIFT] and pressing a pad, sample playback is stopped. If the sample is not playing, the slot is cleared.
  • Pitch Play Mode: Play from a hot cue point and change the pitch in semitone steps. Pads right of the white lit pad raise the pitch, pads left of it lower the pitch. Hold [SHIFT] and press a dimly lit pad to select hot cue point. Use the PARAMETER buttons to cycle though different semitone ranges (Up, Mid, Down).

The other modes that are described in the owner's manual (Slicer, Slicer Loop, Saved Loop, Flip) are currently not mapped.

Known Issues

  • TR-S Syncing currently works at the BPM level, but phase syncing is not implemented yet. As a workaround, the NUDGE button can be used to adjust the phase. This depends on MIDI clock I/O (Launchpad Bug #682221).
  • Some performance pad modes are missing (Slicer [ Launchpad Bug #1828886 ], Slicer Loop, Saved Loop, Flip)
  • Buttons for sorting the library by BPM/Song/Artist/Key are not mapped since no Mixxx controls seem to exist for it (Launchpad Bug #1828882, GitHub PR #2118)
  • Some buttons are not mapped yet (e.g. BACK)
  • LEDs on BACK/ADD PREPARE do not work (this seems to be a hardware/firmware bug and does not work in Serato either)
  • Controller does not send current cross fader value on Serato Sysex Message (this seems to be a hardware/firmware bug and does not work in Serato either)
  • Support for colored hotcues has been added, but depends on PR #2030 which has not been merged yet.
