MIDI Expander for Helical

By connecting the USB Micro-B port to Cuh (MIDI Expander), Helical acts as a USB MIDI device and sends:

Note messages
CC messages for all knobs and Lock switch
⚠️ Do not connect Helical directly to MIDI gear without using Cuh. This may cause overcurrent and void the warranty.
Cuh blocks power from USB Hosts for safety.

Helical/Cuh act as MIDI Devices only. To use with MIDI Hosts, an external converter is required.
