RGB illuminated rubber pads meets DARK metal home
Visualize and remember mapped MIDI actions with your favourite colors
Traktor user can map all NI hotcue type colors
The idea behind Dark FIRE
The DARK family grows .. here is our 3rd controller, Dark Fire offers RGB illuminated controls for DJ’ing and MIDI applications. Available (ready to build on request) since Oct. 18, 2020.
The idea of such a controller was in our mind since 2 years, but we first had to gain our experiences in industry assembled printed circuits in order to realize it (QFN sized SMD chips were needed).
Background: Many user (me too) love to use hotcues in the mix, and as a long year Traktor user I wished always to have this beautiful Traktor hotcue colors on my controller. Blue/green/orange/white was needed, and supporting any RGB color could cover even more use cases.
Dark Fire feels like “made for Traktor” but the midi compliant protocol allows to trigger midi application outside the Traktor world too, that’s why we love it. And the usb bus powering and portability allows a nice mobile setup with DJ Player Pro (iOS).
Dark Fire is a sibling of Dark Wheel. We replaced the Jogwheel and Pioneer panel with RGB illuminated silicon rubber buttons. And we kept the rest: the flexible firmware features (e.g. customizable Shift, Bank, Deck layer) and all other controls (MEC switches and encoder), even their midi messages are exactly same. Funny story: when I connected my Dark Fire the first time and launched Traktor a smile came over my face: all controls in all 4 decks worked well because the earlier Dark Wheel mapping was linked ; ).
Metal case and silicon pads .. does this fit together? We feel the tactile resistance of silicon pads (allowing strong and fast strokes) complement perfectly to a rock solid metal case, in design and in usage. It makes a lot of fun, feels like ‘made to firing actions in live performances’.
Each pad can be midi triggered with any different RGB color (125 values, not 3-7 only as many competitors), this makes Dark Fire universal: Colors remind me on controller what is mapped (e.g. magenta & green for Cue/Play on lower pads), even complex mappings keep intuitive and memorizable in different layers.
Dark Fire is size compatible to Dark Fader and Dark Wheel, they all work perfectly together.
For more details to firmware features (customizable Shift layer, 2 to 4 Banks, 1-4 decks) see: midi concept (on our Dark Wheel site), Dark Fire supports the exact same features too.

Dark Fire Features
ENHANCED MIDI MAPPING CONCEPT
- Each control sends and/or receives unique MIDI messages for individual MIDI mapping. MIDI class compliant protocol, no drivers or
additional software needed
- Additional firmware features: 3 buttons are highly customizable: DECK SELECT, SHIFT and BANK (via built in ‘Power-On Configuration
Setup’). These buttons can be customized as ‘normal buttons/LEDs’ with MIDI In/Outbound OR as full automated controls (the firmware
covers all logic, the mapping keeps lean)
- Examples: DECK can toggle between decks (A/B, A/C, ABCD…), SHIFT can add an additional layer, BANK can enable 2-4 bank layers
- Users can customize ‘their’ Dark Fire to their needs – from a single 1 deck controller with a few control to a multi-layer multi-deck device
- This concept allows easy mappings with one mapping file, independent of the number of decks or connected Dark Fire controllers
DECK SELECT Button
- Typically customized to toggle between decks (MIDI channel). User can customize behaviour (e.g. button only, deck assignments etc.)
- Bicolor illuminated button (red/green), MIDI I/O mappable or firmware triggered
- Dark Fire stores selected user mode and last used deck/channel on next Power-On
- All PADs can be separately mapped to different MIDI actions or LED colors. Unique layer notes allow multiple assignments
- The 10 translucent PADs with RGB LEDs complement perfectly, allowing to assign DJ APP SPECIFIC COLORS, as well as DISTINGUISHING
ACTIONS in different layers
- DJ APP SPECIFIC COLORS – Example: Mapping of all Traktor hotcue type colors to the PADs (e.g. CUE=blue, LOOP=green etc), or adding
additional colors (e.g. RED for deleting HC)
- DISTINGUISHING ACTIONS – Unique colors simplify multiple layer mappings considerably, allowing intuitive and easy to memorize. Example: the 2 bottom PADs could be mapped to CUE (orange) and PLAY (green), on SHIFT layer as NUDGE pair with any different colors
RGB PAD Colors
- RGB LEDs consist of 3 LED colors (R, G and B), each support 5 intensities, resulting in 125 mix colors in total (5x5x5 cube model), values: R=0,25,50,75,100 | G=0,5,10,15,20 | B=0,1,2,3,4. All PADs can be color triggered with MIDI note values (e.g. 52=red50+green0+blue2, results in mid intensive magenta, or e.g 124=full white)
- Dark Fire offers an inbuilt COLOR EXPLORER in the ‘Power-On Configuration Setup’. This feature allows exploration of all supported colors, calculates the mixed color value automatically and presents as note value in any MIDI monitor
- LED BOOSTER: PADs can be adjusted on-the-fly, allowing adapting between bright daylight or dark club night settings: Press & hold DECK SELECT and push left ENCODER to toggle thru 3 intensities (dimmed/normal/boosted)
- Two Push/Rotate Encoder (20 TPR) with full metal knobs and top shapes. The low pressure and short-stroke encoder feels very pleasant
- Free for mapping, in Traktor typically mapped to Beat jump (left), Looping On/Off/Size (right) and e.g. to FX controls in additional layers
- Two unicolor LEDs (orange, blue) close encoder with MIDI receive inbound
- Bicolor illuminated button (red/green), MIDI I/O mappable or firmware triggered
- Users can customize SHIFT button behaviour as ‘normal button/LED’ with MIDI In/outbound or a button which activates a 2nd SHIFT layer
(modifying notes of other controls)
- SHIFT layer can be activated during hold (default), optimally also latching toggle mode possible (this allows the usage of SHIFT as an additional BANK button)
MID BOTTOM BUTTON
- Unicolor illuminated button (LED blue), free for user MIDI mapping
- MID Button offers layer specific notes (same as on all buttons) and a global note to simplify mappings of DJ application SHIFT notes
BANK LAYER BUTTON
- Bicolor illuminated button (red/green), MIDI I/O mappable or firmware triggered
- Users can customize BANK button behaviour as ‘normal button/LED’ with MIDI In/outbound or a button which activates 2 or 4 banks
(modifying notes of other controls)
- BANK button can be customized similar to SHIFT (2nd bank on hold, kind of an additional SHIFT), or in latching mode (default). Button walks thru all 4 banks in 4 bank mode
- Any combination with SHIFT supported, results in max. 2×4=8 layer in total (32 in 4 deck mode)
POWER-ON CONFIGURATION SETUP
Holding a BUTTON during power on activates the ‘Power-On Configuration Setup’, allowing customizing user settings/preferences
All changes are stored permanently. Supported setting options (holding dedicated button, using Hotcue 1-4 to select favourite mode):
- 4 DECK MODES: normal button/LED – 2nd deck on hold – 2nd deck latching – 4 decks toggling
- 4 ABCD MODES for 2 decks: A/B – A/C – B/D – C/D
- 3 SHIFT MODES: normal button/LED – SHIFT layer on hold – SHIFT layer latching
- 4 BANK MODES: normal button/ LED – BANK 2 on hold – BANK 2 latching – 4 BANKS
Additional customizing, holding:
- SHIFT + BANK on power on: RESET to default settings
- PUSH RIGHT ENCODER at Power-On: Activating built in COLOR EXPLORER

How to upDate your Dark Fire Firmware
Many tools are available to upload firmware into Teensy based controller. We recommend the tool ‘TyCommander’, part of the open source TyTools project (from Koromix). TyCommander is easy to use, available for Windows, Linux and macOX, no install procedure needed; you can directly launch TyCommander after unzip. A big ‘Thank you’ to Koromix!. Workflow instructions:
- Download latest version of our firmware collection, use left ‘Firmware’ link.
- Open the zip file, inside you will find all firmware (.hex files) of all Dark Controller
- Download latest TyTools (use left ‘Uploader’ link), extract TyCommander
- Launch TyCommander (no install needed)
- Open 2nd tab ‘Serial’ (between Information and Options) to open serial monitor
- Connect your Dark Controller, the current installed firmware version gets displayed
- Check your current version: the 12 digit prefix (e.g. DFIRE1.0-32-) must match to one of the downloaded .hex files. Contact us if you can’t find a matching download version
- Press arrow button ‘Upload’ and select your downloaded hex file with same prefix
- Wait few seconds until upload process finished. Disconnect Dark Fire .. DONE
- Let us know if you need support at any step – always welcome!
Traktor: All 8 RGB pads are mapped to HOTCUES, supporting all Traktor hotcue types. We mapped the original gui colors to the controller. We even added additional colors, e.g. red in shift mode (for deleting hotcues). On the bottom pads we mapped CUE and PLAY with a nice magenta and green (inspired from Denon controller), the CUE/PLAY button change to cyan in SHIFT layer (when they work as Nudging pair). The encoder pair supports the Traktor typical features Beatjump and Looping. On BANK 2 we use the encoders as FX controls and the PADs to control NI STEM channels.
DJ Player Pro: DJPP does not support different colors on hotcues (unfortunately), we hope that DJPP will this support this in future. But Dark Fire feels still great with DJPP because the portability (no powering needed) and flexibility in mapping. We mapped one standard color on hotcues (blue), and added additional colors depending the workflow (e.g. red for deleting hotcue or green/white in FX pad mode). A friend of us made powerfull mappings (2-deck mappings, mirrored A/B controls on same layer supporting DVS features). And we found a totally different and inspiring use case with DJPP: Triggering songs in stem format feels great with Dark Fire: 4 hotcue controls (left pads), 4 Stem on/off (right pads) using stem songs with sample. Using deck C and D for this (similar to remix decks in Traktor) allows nice background beats and samples for techno DJ mixes.
Ableton or Serato: We did not test yet, but quite sure the RGB pads and encoder would allow nice workflows, exited to see some first user ideas.
Beyond the DJ world: Dark Fire is MIDI class compliant, so not restricted to DJ world. We have user who even use Dark ‘Fader’ for triggering video cutting systems or as main stage light controller. Quite sure user may find use cases for Dark Fire we even never thought about.
INSIGHTS INTO THE TECHNICAL CONCEPT
Some technical details may inspire you to build your own controller:
Dark Fire architecture is based on the universal Dark Board combined with a Dark Fire specific 2nd layer PCB (Printed Circuit Board) as carrier for all controls. Both PCB are connected via I2C bus (similar Dark Wheel)
We decided for the well known Sparkfun silicon rubber button pads for the 10 pad controls, they feel best for us (in particular for strong strokes). The LED inside allow a nice optical feedback. The challenge was the circuits and PCB assembling. Tech folks may know the published hook-up guides and breakout PCB from Sparkfun, they do not support any real (means stepless and dimmable) RGB color mixing. Their circuit can toggle the 3 colors on/off only, a real color mix (dimmable and stepless for each color) is not possible with Sparkfun circuits – they mentioned it is too complex and too power consuming. So their circuits was a No-Go for us, we wished to allow mixing any color. We decided to build our own circuits (as carrier for the Sparkfun silicon pads). In our circuits we trigger each LED pin separately (not using any key matrix simplification) and made them dimmable. State of the art IC technology was needed; hundreds of connections are only possible in smallest SMD package sizes (QFN-UT), often used in smart phones. Manual soldering is no longer possible, so we moved over to industry built and assembled PCB (Printed Circuit Boards) on our plans. A huge learn curve for us, and we are quite proud about ; ). The Dark Board below (the PCB with Teensy, hub and connectors) are still hand soldered completely.
The second big challenge for us was the power consumption. Competitive controller with RGB pads are wasteful often, 10 pads end typically above 500mA, also No-Go for us, as Dark Controller should be USB self powered, even on iOS smart phones. We combined several concepts, our Dark Fire needs less than 30mA for all LED (even if all are shining in brightest white), so the complete controller (including Teensy, hub and all components) consumes about 100mA only (even in case all LED are triggered in maximum) – so we keep mobile, no hub needed at any smart phone : )
The firmware of Dark Fire is similar to Dark Wheel, we embedded the same flexible MIDI mode concept (user customizable DECK, SHIFT, BANK features). We enhanced the Power-On Configuration setup with a nice “‘tell me the color value” feature, the COLOR EXPLORER. Background: Supporting 125 different color is powerful, but the user may ask the question which value ins behind each color (for self made mappings). So we added in Power-On Configuration the feature to mix any favourite color (with pads & encoder) and display the color value result in any MIDI monitor (e.g. in the DJ Payer Pro monitor). So the user knows which value he has to add later on in his self made mappings.
The rest of the technical concept in Dark Fire is as expected: full metal chassis with CNC made panels, brushed and double black anodized 3mm aluminium, polished bare metal side surfaces, industrially produced PCB (SMD assembled) with black glossy surface and immersion gold contacts. USB-IN to MIDI host, optionally mounted USB hub and USB-A OUT to connect additional Dark Controller or user MIDI devices in daisy chain.
PROJECT STATUS (HistorY)
Update Dec. 26, 2020:
- New Pictures uploaded (SLR made).
- Added 3 images pictures with different LED colors on RGB pads (power connected via usb). All colors are real: Shooting LED is difficult due the low dynamic range of camera sensors, so i used a SLR, mounted on a tripod and HDR filter to mirror reality as best i could. I did not use any ‘faking Photoshop coloring’
