CTR2-Flex Firmware Manual – v2.05.02

July 5, 2026: v2.05.02

• Updated CTR2-Flex and CTR2-Dial firmware to v2.05.02 – this update fixes a bug in CTR2-Flex that caused all knobs to control the selected parameter in the Dashboard. Now, only knobs set to the <DIAL> function control Dashboard parameters.

There is a separate manual for CTR2-Dial firmware. You can download it here.

• Starting with v2.04.00 I’ve split the hardware descriptions out into three separate manuals:
  • CTR2-Uno
  • CTR2-Duo
  • CTR2-Quad
  • You can use the hardware manual for CTR2-Uno and CTR2-Duo for the older single and dual-knob CTR2-Dial and CTR2-Flex hardware.
• You can download the CTR2-Flex/CTR2-Dial firmware here.
