Has Casio dropped the synth edit from their arrangers now? In the specs you don't see it listed anywhere with these new models. With the models they've released I see they've added things such as 48 note poly, sampling (although quite basic), and a pattern editor as well, and increased seq note capacity up several thousand notes. Perhaps they swapped out the tone edit for these new features.
I always thought the Tone Edit on these lower end Casio's was a great feature for the novice to get their feet wet. It looks like the Tone Edit is now for the higher models.
