Hello...newbie here...I have Studio Drummer which I am trying to multi-output into Logic Pro X. I have a Roland V-Drums TD-17 kit. I cannot make them work. I am at my wit's end. I would like to be able to use sounds from Studio Drummer but also the Roland brain (as a secondary sample source). I use a United Audio Volt 2|76 audio interface. There has to be a way to use the three together. Any help would be appreciated!!!
