Hello,
I'm sorry I didn't write how I got it resolved, I just thought that nobody was interested in it really. In truth, there's not much to write. I just did as told, and it worked after a few tries. When I had made the changes to the song in the mixer that I wanted, I pressed creater, then [a] for song creator, then page right to go to the channel tab, then four times to get down to setup, and finally I press [d] to excecute, and then I can just save the midi-file the normal way.
As I'm blind, I can't tell you exactly what is happening on the screen during this process, but this is the way I do it.
Kind regards:
Aksel Christoffersen
