No quite a different instrument. The PX-5S has a more powerful synth engine (PX-5S can do  dual hexlayers - PX-560 can only do one),  PX-5S has 4 arpeggiators, 560 has one). PX-5S is also a more flexible MIDI controller. BUT.. the 560 has dedicated transpose buttons, an assignable pedal input for an expression pedal, a large color touch screen and a music stand. PX-560 also has a multi-track MIDI recorder and backing rhythms.

 

I think the 560 can do a hex layer on each Upper1/2,Lower1/2. It's not to be confused with E-23 "Apply effects to Upper 1 (main tone)". I believe (I don't own yet!) this means that when you are sound designing the sound comes out of Upper1. You can then save this sound preset and can then stack/layer/split that saved preset allowing upto 4 Hex layers being played at once. A maximum of 12 voices per note.

Or am I grossly mistaken?

Looking at page EN-27 looks to have a Portamento On/Off... would this mean that this can be used for Mono type synths? This was something that was missing from the PX-5S.

Also, the 560 can layer up to 4 Hex Tones, one on each of the Upper1/2, Lower1/2 layers meaning it's got a more powerful processing engine than the PX-5S. I think that's right?...
