This module will give you the standard midi connectivity with 2×3.5mm jacks. You will be able to connect directly to sound modules or MIDI devices.
The CV/Gate interface is also provided (1/V Octave) to control analog synthesizers.
As explained below, EXP-1 is also able to provide conversion between various protocols:

USB to midi conversion
With this module, the EXP-1 can act as a an USB <-> midi converter. You can use it for example to connect a midi keyboard to a laptop which has only USB port.

USB to CV/Gate conversion
You can, for example, control a modular analog synth through USB by doing USB to CV/Gate conversion

MIDI to CV/Gate conversion
You can, for example, control a vintage analog synth which is not equipped with MIDI by doing MIDI to CV/Gate conversion

The channel 4 is used for theses protocols conversion. For example, All the MIDI traffic of the channel 4 entering on USB will be forwarded to XPANSION MIDI on channel 4 and the same on the other sense. Note that only Note ON, Note OFF will be forwarded.
