You can download the operation manual for CTR2-MIDI here. It will be updated when new versions of the firmware are released.

v1.01.00d of the operation manual update includes a new procedure for flashing CTR2-MIDI firmware to ESP32-S3 processors without requiring the Program button to be pressed first.

NOTE: The latest version of Adobe Reader doesn’t know how to deal with the hyperlinks used in the Table of Contents. Open the PDF file in a browser for a better reading experience.
