MIDI Designer receives MIDI cc data and will move the controls that are mapped. If MIDI Designer is "going crazy" then it must be some MIDI data that is coming to it that is not expected... use Snoize MIDI Monitor (on Mac) or MIDI Ox (PC) to figure out what's up with your MIDI, first. Then circle back.
Regarding button changes: buttons for what? MIDI Designer responds well to most button change feedback from Live.
Thanks.
