I can’t figure out what I’m doing wrong? I’m trying to trigger EZ drummer with my Roland TD27 using USB over MIDI. I have the TD27 selected as my preset. But when I hit one of the pads on my Roland kit, I can see that it’s triggering the EZ drummer kit, but I get no sound. I’m not using an audio interface and I have the PC’s headphones selected as the output. When I hit easy drummer using the mouse, I hear sound. But no sound, just a visual confirmation that the EZ drummer kit is getting triggered thru USB/midi. What am I missing here? Most likely something obvious and stupid?
