Hi there @tomthebom
In essense you can force the Push2 inside User Mode that allows you to map it as any normal 'midi' controller. You will lose the LCD options, but all other options should work fine, also see this article on their website

If you then connect it to Isadora you should be able to see the Incoming Midi Messages inside the Status and Monitor windows. If you know that you will be able to make some nice User actors / Macro's for it
