I should have gotten this synth back in 2005 when it came out. Instead I got it 2014. The factory patches are good, but it gets even better when you start making your own sounds and performances, especially when working with the Arp Manager program to create your own arpeggiators. The expandability with the PLG boards is another plus, even though it takes some time to get into how these boards are operated.
This thing is an absolute beast. The AWM2 sample/synthesis engine is surprisingly deep, and both acoustic and electric pianos sound luscious and wonderful. The interface is geared towards live performance over sound design, but you can navigate around it pretty quick once you know what you're doing. It's a joy to play in studio and a godsend to perform with live.
