For audio drums - what kind of control do you have?
When you say midi triggered - please explain - ie c# is a hat wav D is a snare wave etc or do you mean something’s else .
If I pick a factory sound with audio drums - can I revert to midi drums ? What if no midi drums were recorded underneath ?

I want to be able to control the volumes the individual drum parts - snare hihat kick etc - can that be done or can I only select other audio drums kits
