I would like to inform you that Yamaha announced their entry level professional arranger PSR-SX600. Sadly its just a cosmetic update from previous PSR-S670. More info in official website.
New in this model:
+ More voices
+ More styles
+ More expansion memory
+ Microphone input ( no line in ) + additional DSP (not vocal harmony)
+ Colour screen
+ Unison/accent function
What's not changed is
+ Not a touch screen (seems like a strange choice not to do that on an "SX" branded model)
+ No R3
+ No step edit
