Dark fader TT

Technics SL1200 pitch fader meets metal Jogwheel
Turn Table workflow in a pocket - MIDI TT To Go

COMING SOON

The idea behind Dark Fader TT

Long story short: We love our Dark Fader and the amazing tactile feeling of an original Technics SL1200 pitch fader. But user who played on TT in past missed something: supporting the complete turn table beat matching workflow. They wished nudging via turns, holding & releasing music via platter fingertip, searching/scratching to cue position. They asked us to place the powerful metal jogwheel from Dark Wheel controller into Dark Fader.

That’s the idea: Keeping the Dark Fader further and welcome a Dark Fader with Jogwheel in our family. Dark Fader TT is targeting DJ’s who search a MIDI class compliant and mobile TT workflow solution.

Technical concept: we integrated the HiRes metal jogwheel from Dark Wheel and made it TOUCH sensitive. The new VINYL mode allows holding and releasing music by fingertip (in addition to nudging in CDJ mode). And we used the moment to complete their idea with additional features:

Dark Fader TT is a full 4 deck controller (4 color LED’s, 4 MIDI channel). And MIDI user might love our new BANK button: offering additional layer for user mappings. The jogwheel simulates standard encoder MIDI messages in additional layer, so can perfectly used e.g. for scrolling in Track browser. Last not least we added more powerful preferences in Power-On Setup for user specific configurations.

Project status (July 2022): Hardware & firmware is Ready to Go, first devices will be send to our beta user in August. We plan to complete all documentation (Datasheets, Power-On Customizing Guide, Printed Manuals) until September 2022.

Let us know what you think about our NEW Dark Fader TT,
Stay tuned!

Dark FAder TT in a nutshell

Dark Fader TT supports all features of Dark Fader (downward compatibles to all messages and customizing capabilities). The additional Jogwheel and controls offers new features and capabilities:

General Enhancements in TT version:

  • 4 DECKS: Dark Fader TT extends the 2 decks in Dark Fader to 4 (4 MIDI channels). Top DECK button fully user customizable, 9 modes available: A, B, C, D, AB, AC, BD, CD, ABCD, no longer different mappings needed. Deck Indicator LED’s in RGB (different colors for all 4 decks), spending 2 LED’s (L/R) for best usability: A/C (left) and B/D (right)
  • 4 LAYER per DECK: Dark Fader supports 2 layer (via SHIFT button),  Dark Fader TT offers an addition BANK button (right below Jogwheel) to extend to a full 4 layer controller (BANK1: Normal / SHIFT,  BANK2: Normal / SHIFT) 
  • CHASSIS: 3 color variations planned: STANDARD (brushed black anodized Alu with Silver stainless buttons), TRANSPARENT ACRYL version and NEW: DARK BLACK with black steel knobs and new Technics SL1210 mk7 fader knob

Jogwheel features and capabilities:

  • TECHNOLOGY: High quality 10bit analog magnetic shaft/hall encoder with high Ticks Per Turn rate (TPT > 600)
  • MECHANICS: Heavy full metal knob, combined with ball bearing axis for long duration high spin support. Supporting highest precision in small movements AND an intelligent dynamical speed acceleration for beat searching on fast swipe gestures. Easy MIDI mapping (no toggles needed, firmware supports both automatically)
  • TOUCH SENSITIV in VINYL mode. CDJ/VINYL button (left below Jogwheel) toggles between the 2 Jogwheel modes: 1. CDJ mode -> Nudging (no touch events), and 2. VINYL mode -> CUE position (scratch) mode with activated TOUCH recognition on complete Metal knob (holding music on finger touch). Using capacitive touch technology (clickless recognition for lowest latency)
  • MIDI CC messages: High speed CC messages in layer 1 (600 TPT for smooth jogwheel mappings), Layer 2-4 send CC Encoder messages (20 TPT). This allows to map the jogwheel easily to any user preferred encoder actions (e.g. for Track browser scrolling or Loop Length)

POWER-ON Configuration SETUP features:

  • DECK modes (NEW): A, B, C, D, AB, AC, BD, CD, ABCD. User can store their favorite toggle mode, user with 2 Dark Fader TT can assign the controller differently on L/R side. No longer need of any modified mapping files, one file for all scenarios
  • SL1200 FADER Customizing (same as in Dark Fader): MID POSITION, MID RANGE, SENSITIVITY, MSTO (MIDI Soft Take over)
  • SL1200 FADER Customizing (TT only): DECK button (MIDI channel toggle) and SHIFT-DECK (for SL1200 PITCH RESET) can be disabled (for user who wish 2 additional free buttons for own favorite mappings)
  • Jogwheel Customizing: Rotate Sensitivity (Noise reduction)
We build on your request

All Dark Controller are hand made, focused on highest quality, using best components on market. We build each controller on user requests.

How we build: we designed all electronic circuits, professional PCB vendors built the Printed Circuit Board on our plans. We constructed a Dark Fader TT Jogwheel PCB module with manufactor assembled PCB components in smallest SMD IC technology (QFN-UT). The metal chassis panels are 3D CAD constructed by us, CNC milling factories built to our specifications. All listed components above and spare parts are typically on stock.

All firmware is coded from us (in own intellectual property), we support further updates, latest versions and mapping templates can be downloaded from our website.

We start the soldering and mounting process with ordering. Each device is manually soldered and mounted by hand. We upload our latest software and test each controller before we send shipping. We guarantee on quality.

Typical delivery time from ordering to shipping is about 2 weeks, we deliver world wide.

Projected Retail Price

We do not know the final retail price of Dark Fader TT yet ; ). We will remain true our vision, handmade controller using best components only, well knowing we can not compete to prices of plastic mass products. 

Recap: Dark Fader calculation (without TT): The retail price (€ 328) is mainly driven by material costs of used high quality components (SL1200 fader, metal CNC panels, steel buttons etc.). We added a fair margin which motivates us to spend the soldering and mounting effort in building your controller in our spare time. 

The Dark Fader TT will be more expensive, as we added a high resolution Jogwheel. The used stepless analog 10bit hall encoder inside cost us currently about € 110 (metal knob and pcb included). So the current USP target might be 328 + 110 = € 438. As said, not finally decided yet.

Let us know if you want to be a Early Bird on Dark Fader TT, we are interested in your feedback and promise you to offer our best price we can!.

And let us know which design you love most: Black Alu & silver steel knobs or Acryl & silver steel or the new Dark style: Black Alu & Black metal knobs (or anything special ; )
