GFI System Specular Tempus
Current Firmware
3.8
Connect via USB. Hold both footswitches while powering on; release when LEDs 1 and 4 light up. The pedal appears as a USB drive. Open SpecLab software, select the .fdt firmware file, and flash. Do not update directly to v3.8 if current firmware is below v3.0 — contact GFI System first.
