Changing instrument for midi track

Hey folks,

in a fresh Cubase 8.5 Pro project, I import a simple midi file exported from Guitar Pro. In the midi instruments editor, I want to change the instrument for that track. For the whole track, but eventually, when I play the the track, the instrument automatically changes back to the old instrument.

So how can I change the instrument in a way, that it is not changed back eventually?

Thanks in advance,

just delete the program Change controler at the begining of your midi file.

does that also apply to ai 8?

i searched the “operation manual”, the 600 plus page pdf and couldn’t find anything.
