OK this is a long shot! I have a fairly ancient electric piano (Roland) which has the facility to input and output midi files. I would like to be able to play back midi files created via PrintMusic through this keyboard but I have no idea how to go about it - or whether it is even possible! At the moment the midi files are on a laptop but I don't know how to attach it to the keyboard. If I did manage to attach it, how would i make it play? Help!
