To import midifiles to Ripchord they have to be midi type 0. I have successfully imported midi type 0 with up to 3 tracks in them. To see what type it is. - Open the mediabrowser and go to your midifiles. - Highlight a midifile and look at the bottom of the mediabrowser window. In its frame is some info about the file. With midifiles you will see the type and number of tracks in it. Most of your midifiles probably is of type 1 so you have to convert to type 0. The quickest and easiest
