The USB Footswitch is a simple, plug and play device to trigger any parameter of your software instrument. Plugging the Footswitch into your USB port, it is immediately recognised by your computer as an audio device. By default CC1 is sent to MIDI channel 1, but you may set it differently using the Eomono editor, which can be downloaded here https://www.eowave.app/members/

The Eomono editor requires Max Runtime to be installed, find the latest version free for your Mac or PC here https://cycling74.com/downloads/
