I played one of these last week at the Moog store in Asheville. It's a cool place where you can try out all of their current offerings on headphones, I had a lot of fun for about an hour playing with their current production line. Their Mellotron was definitely fun to play, easy to use, and really unlike anything else they offer on the showroom floor.. but I didn't know it was going for two grand! I'm going to be the spoiler here and tell you what Rick Wakeman already knows: Mtron Pro by G Force software. The time and effort they have expended to sample original Mellotron tape libraries is impeccable. I love the Mellotron, and had the experience of playing and loading tape banks back in the day. The GForce emulations are exquisite, and I never use the word 'exquisite'.
