I own the Motif XS (have had it since its release and its still going strong)

I am hoping for Yamaha to allow up to 6 or even better - 8 arps to be layered simultaneously as opposed to just 4 in performance mode...

then you will be able to have full proper arranger-like backing and performances in real time...

also the MOXS and MOXF have dedicated buttons on the keybaord for layering voices and transpose which the Motif XS and XF do not...

Touch Screen? I dont know if im a minority or majority here but I honestly dont really see any need for a touch screen on the Motif. from what i see in the motifator forum its never really on the wish list... navigating through the Motif is always a breeze. things could be quicker with some short cuts and better planned out Operating System IMO.

Hopefully we see some major changes on the new synth whenever it comes out...
