Hi guys! I need a hand with mixing drums in Cubase 10.5 Elements.
Am using Superior Drummer 2 VST, Multiple Outputs in Cubase; (Kick, Snare, Toms, OH, etc.) And inserts With Slate digital Virtual Mix Rack and Virtual Tape Machines. The problem is when a finish the mix, the project almost crash… Slow and not responding to anything. What can I do¿? Anyone with a similar situation¿? =(
