I remember you & Moon having a discussion about the M3,but I didn't realize you had bought his M3.
Speaking of being spoiled by pristine pad sounds,I am very much spoiled by not only the pads of my Kurzweil PC3LE6,but pretty much every synth sound in this keyboard.
It's such a shame that Kurweil's UI is so poorly done,in contrast to that of Korg's..because Kurzweil's VAST engine is hands down,the absolute best VA synth out there,in my opinion.
Though the PC3K series is interesting,it seems the UI hasn't changed,but I have heard some buzz over there being a K3000 series that's in development.
