Interesting, I had forgotten about the Scenic effects. Scenic is Gorilla Engine based and the effects are near stock form so you could emulate a lot of RE's with these modules.
Processed Pianos also gives you access to a lot of the GE modules - Lo-Fi, Frequency Shifter, Chorus, Filter, Multi-Tap, Reverb, EQ and Compressor are all there for Combi2 use.
