How about that it's a completely self-contained instrument with an authentic
design and layout, appears to have a decent build quality, seems easy to
load with sounds, has a nice thin profile for keyboard stands, full-sized
keys in the proper range, and the implied ability to create multi-layer and
split combinations for starters? Obviously, sound will be the crucial
element, but I find it difficult to imagine somebody would undertake an
obvious tribute to an instrument that has such unique sonic characteristics
without paying attention to that little detail! Mellotron folks, it's not
too late to build your own - remember what the DX7 did for Yamaha? Imagine
a Mark II version of this thing... how fun, cool, and easy would that be
onstage? Talk about a fantasy instrument - most of the pleasure combined
with portability and low maintenance, not to mention replaceability if the
worst would happen.
