While we tried to recreate the sound of the original effects as accurate as possible, we added a few knobs to make them more versatile. You can control the width of the stereo field and mix between a dry and a wet signal. Furthermore, you can change the depth and rate that in the original organ were fixed.
When you leave the knobs Depth and Rate in their default settings, you get a close approximation of the original Eminent/Solina sound. However, changing these values can be great to create a little variation for different instruments you run through the effect. After all, you are not limited to the few basic sounds that came with the organ.
A last difference: you can make a smooth transition between the different modes, like the transition of the effects of a Leslie speaker. A feature that is so convenient that it makes us wonder why the makers of the Eminent didn’t add it.
