Yes the Genos hs all those sounds, the Scat has the wave cycling technology, others have the second Super Articulation, and I am also familiar with the Electones, that one has the most but the Super Ariculation 3 that Genos has....some sounds.

I also know that the Electone ELC has a technology that is not avaialble in any PSR SX , Tyros o Genos....is a side touch vibrato, I used that when I was playing a Violin, trombone, trumpet, electric guitar, etc....comes very handy giving the user a more realistic way of interpretation of such instruments....
One thing that also the Electone does not have is the Mulipads, or at least the Audio link to multipads or the capacity of adding Expansion Packs.

My 2 cents.
