I'm pretty new with this but I'm using SI Drums in a project doing nothing fancy just kick hat and snare using my Avid Keyboard controller. I did a ton of takes overdubbing the high hat a bunch of times and listening back. Suddenly I get no audio from my drums. Nothing is muted, nothing is soloed all the audio recording tracks are fine, just no signal going to the master bus and the keyboard triggers the plug in but no sound at all. Looking at the kit window it responds to keyboard and mouse clicks but gives no sound.
I started a new project and brought in SI Drums and it works fine. It must be something I did in my project. Please help. I've attached a screen shot of the project just to give the basic idea how things look on the surface.
