Allo!

Meine Deutsch ist zehr schlecht. :)

So I'll write in English.. sorry :)
I have a question, regarding adding the chords to my midi files, so that the MIDITEMP MP11 can play them..

The midis that came with the machine contain chords, and now I want to add the chords to the rest of my midis, which program must I use?

Thank you for your answer,
Danke!
