Annex

The Annex chapter gathers the procedures you only run occasionally — firmware updates, hardware tests and CV calibration. Skim them once when you receive the module, then come back when you need them.

• How to update the firmware — flash a new firmware image via the Teensy Loader.
• Test mode — exercise every input, output and front-panel control to validate the hardware.
• Calibration — calibrate the 1V/Oct CV inputs (main module CV A–F, expander CV G–L) for accurate pitch tracking.
