Hey OlympicCarrier, thanks for your reply. I didn't write earlier because I was trying to find some way. And I found, but half way. Here what happens: when I open the mGB Editor.als ALONE in ableton, and then insert a midi track, it works like a charm. All midi CC goes beautifully to each dmg channel. But when I try to open the instrument rack inside an already created file (in that case, my whole set), none of the effects work.
In both files (the mGB.als and my set.als), the mGB editor midi out is to my controller. But it only works when I don't open it inside a file created earlier.
Any idea why does it happen?
