I have 1 instance of groove agent going with multiple kits in it. I want to layer a kickdrum. I have 1 kickdrum from 1 kit in Groove Agent as C1 in the keyeditor. In a second kit I find a nice sound that I want to layer on top in the key editor. Its on f1. However, when I change midichannel in the keyeditor, nothing happens, while the midichannel in the Groove Agent is routed to channel 2. How can I fix this?
