Thank you, you’re right and I see what happened. When you use the search field, it combines algorithms and presets together in one list, but the Algo box stays lit up, making it seem like the presets are algorithms.
So tell me, for instance, about algorithms 4243 and 4245 – Large Room2 and Really Large Room. They have the exact same parameter layout. How different are they in their actual coding/design, rather than just the default values that they load with?
