Using the LehLe Expression Pedal with USB Host

The Lehle Dual Expression and Mono S expression pedals both have a USB device port which can send MIDI over USB. The CC message that is sent is fixed, which is a CC#11 message on Channel 1.

To use this with the MC PRO series USB Host port, you'll need to utilise the MIDI Message Converter function in the Controller Settings tab. You'll need to convert this incoming CC#11 message to a CC#51 -CC#54 message (depending on what Expression Preset you want to control. Please refer to the MIDI Implementation chart for more info).

This will convert the CC#11 message to a CC#51 message at the Input (which means before the CC message is processed according to the MC MIDI implementation). This will allow you to control Expression Preset 1.
