DB-33 is great for a tonewheel organ VST with a correct set of controls and an amped tone cabinet. The CPU usage of DB-33 is as low as it gets with virtual instruments. All of the controls on the organ and the cabinet have MIDI learn... right click each control. You only have to load the organ to have both the organ and the cabinet active. Switching between the organ & cabinet interfaces is one click of labeled buttons. The slow/brake/fast lever is animated and works with MIDI cc 1 mod wheel by default. You can use the cabinet as a separate plugin. If it's producing some static with the tone, adjust the cabinet's [organ] knob along with [master] volume. [organ] usually ends up pointing straight up to 12:00 or maximum of 1:00 on mine. Master volume on both the organ and cabinet are the same control, so you don't have to manually match them. You can see it all in the demo version. I guess there is no standalone DB-33? There are ways to simulate it as a standalone organ though. Five of five stars.
