I recently purchased a used Presonus Faderport to use with my Mixpad Multitrack software. Howeever, It doesnt seem to want to work properly... the software recognizes the controller, but I cant get the functions on the controller to work properly... I have been working with the Midi menu in options but again, it reconizes it but I cannot get it to work more than one command at a time. Is that all that it is suppose to do. Can someone help Please!
