I know nothing about Midi files because I don't use other people's ideas. I have never downloaded any into the keyboard. I do complete original arrangements on the KN7000 and have a digital recorder with a built-in CD burner. Can't I burn the arrangements to CD and then put the CD in the computer and file it as a WAV? Since Midi files are a form of recorded music, will this work? The reason I want to make my arrangements Midi files is because I want to use Musescore to write the full arrangements. The only way you can use the program for writing full arrangements is that they must be a Midi file.
