Hi Leeboy
Yes you can connect any Midi Keyboard/pedal board to the Pegasus wing, and it also has a dedicated section for pedals so that you don’t have jump through hoops to set it up. (Wersi (Music store) may also re-introduce dedicated pedals in the future, but this is pure speculation at present)
You can download the English brochure here http://www.wersidirect.com/www.wersidirect.com/Pegasus_Wing.html
Hope this helps
