As always, opinions vary, Frans...I just feel, if you were going to the trouble of having two keyboards, that it would be best to have different tone generators in each instrument.

Personally, I wouldn't go with two arrangers/keyboards...the Tyros4 (with 1 gig expansion board) is more than enough for my needs, having SA/SA2 Voices (available in styles) and oodles of factory and third party support. I am a very happy camper.

It is nice to see DNC2 being added to PA-600...a good move by Korg....I think it is a great bang-for-the-buck arranger.

PS...I don't use Vocal harmony either, but I run a small Yamaha CS-01 Analog Mono Synth through the Tyros4's VH-2 for pseudo-polyphonic retro sounds with effects...it's a hoot! Worked well in the S910 too!
