The Random Spaces presets are comparable to the Room presets. The majority of the presets are similar to those in the legacy Rooms preset bank.
However, the random delay elements make the rooms seem more "live". These elements are key when you want to create an atmosphere that is busy or has movement. The "Chorus Room" and "Wet & Tacky" presets have been optimized for a chorus effect that provides spatial qualities.
