remixvideo MIDI mapping issues

Couldn't post in "MIDI mapping" section, so I'm doing it here.
1) I have a Korg nanopad and I want to map it the xy pad to video effects and it's not working
2) I would like to map a slider on my APC20 to the blend modes dropdown menu and it doesn't work. Any way to do this?
