hello, please help me, I have a roland fr 4 accordion and I use it with the native kontakt instrument via midi. the problem is that I have no control over the volume, I entered the midi settings in roland and tried to change the volume, but kontakt does not receive the midi volume information, I also tried in cubase to see if roland transmits volume information via midi but I didn't succeed. I don't know what settings need to be made, in roland or in contact, to be able to control the volume via midi.
