T-4000 Software: 4-Output Matrix LED Controllers

Program T-4000 4-output matrix LED controllers with LEDEdit Pro 2026: 4 outputs × 2,048 LEDs in the export profile, TM, TM19, P9813 and SM16716 chip profiles and direct .led export.

The T-4000 sits between the single-output T-1000 and the eight-output K-8000 / T-8000: four outputs for matrices, signs and medium-sized installations.

T-4000 in LEDEdit Pro 2026

  • 4 outputs, up to 2,048 LEDs per output in the export profile.
  • 4 export-ready chip profiles: TM, TM19, P9813 and SM16716.
  • Full editor workflow: layout, layers, effects, text and per-LED preview.

Example: two matrix panels plus an outline

PartLEDsOutput
Panel A, 64 × 322,048p1
Panel B, 64 × 322,048p2
Outline strip900p3
Total4,9963 of 4 outputs

Each panel exactly fills one output, so stamp them with Pattern Builder on separate ports.

Tips

  • If your pixels use a chip that is not in the T-4000 list, check whether a free LEDEdit version supports it and use the DXF + AVI fallback.
  • Watch the Used column per port — a full output leaves no room for “just a few more” LEDs.

Chip profile notes: WS2811 / WS2812B

The T-4000 family does not list a dedicated WS2811/WS2812B chip in data/lep_controllers.json — its four export-ready profiles are T-4000-TM, T-4000-TM19, T-4000-P9813, T-4000-SM16716 (plus listed-but-not-exported T-4000-TLS). For WS2811 / WS2812B pixels on a T-4000, use the closest driver timing available for your strip: T-4000-TM or T-4000-SM16716 are the most compatible for 800 kHz single-wire WS2811/WS2812B, then set colour order GRB for WS2812B and RGB for WS2811 in the export dialog. Test a short chaser first; if colours are swapped, flip GRB↔RGB — see wrong colours on WS2811 fix. If the panel shows flicker or dark pixels, verify the controller label — many WS2811 installs actually use a T-1000S or K-8000 family with a dedicated WS2811 profile. T-4000-TLS is listed but not yet exported.

5-step export to SD card (T-4000)

  1. Map LEDs per output — In LED Layout Creator stamp Panel A 64×32 on port p1 (2,048 LEDs), Panel B on p2, and the 900-LED outline on p3. Keep Max LEDs/port = 2048 and confirm each port’s Used count.
  2. Animate per zone — Create three layers (Panel A, Panel B, Outline), paint masks, and add effects — see timeline and scenes and the Christmas lights guide for a T-4000 house example. Preview per-LED, or watch the video tutorial.
  3. Choose profile — Output → Export LEDEdit .led → family T-4000 + chip T-4000-TM (or P9813/SM16716/TM19 to match your pixels). Set colour order and FPS.
  4. Preflight & write — The dialog shows 3 of 4 outputs used, 4,996 LEDs total and scenes. Export the package, then Write to SD Card or copy .led files to the card.
  5. Test — If the 4-output scan looks torn or the tail stays dark, see last LEDs dark and SD-card not playing. For chips not in the T-4000 list, export DXF + AVI and build the final .led in free LEDEdit — fallback guide.

FAQ

How many LEDs can a T-4000 drive?4 outputs × 2,048 = 8,192 LEDs in the export profile. Keep each output under 2,048 — a full port cannot take extras.
Which WS2811 / WS2812B chip do I pick on T-4000?No dedicated WS2811 entry for T-4000 — use T-4000-TM or T-4000-SM16716 for WS2811/WS2812B 800 kHz timing, then set GRB for WS2812B and RGB for WS2811. If colours are inverted, flip the order — wrong colours fix.
Why does the outline not light or colours look wrong?A full output (2,048) leaves no headroom — move overflow LEDs to the free p4. Swapped reds/greens = colour order; flicker/dark = wrong chip timing — verify the controller family and try the DXF+AVI fallback (fallback guide).

  1. Map your LEDs in the LED Layout Creator or import a DXF layout, with one port per controller output.
  2. Build the show with layers, clips and scenes on the timeline.
  3. Open Output → Export LEDEdit .led…, choose the T-4000 family and the chip type of your pixels.
  4. Check the preflight (controller, chip, colour order, scenes, frame rate, outputs, LEDs) and click Export.
  5. Copy the files to the SD card, or use Output → LEDEdit Tools → Write to SD Card….
