Thanks, then I know. I will try out the suggestions.

I have the melody and the whole song as well in midi.
I just wanted to see if I could load upp the chords from the piano track only (the instrument playing the chords).
It worked out fine for some of the songs but not for all.

I have just tried out to add some dummy quarter notes as well as a whole to set the start, but it still iterprets some of the chords and rythm incorrectly.
I guess it is the tripplet timing that might cause the problem.

I leave this for know, I just wanted to know.
No big deal to type in the chords manually.
