Either you like the Mellotron or you don't.  Nowadays, I suppose that real string sounds are widely available but if you want that 60s - 70s sound of what we used to have deal with when we wanted strings and didn't want to deal with a thin sounding Farfisa or some other string machine - here you go.  Don't have an opinion of how usable the midi is because I usually can play in a pad or one finger it in.  
 
One thing to try is to bring up the flutes and try not to peck out the intro to "Strawberry Fields".  Couldn't resist it.  

Although I have many Toontrack items and appreciate their products, I think I'll pass on this one.  Not really feeling that "sound".
 
I'd like to see them work on a bass vst though.  

I have the UVI Mello that I received for free...that's good enough for me...

John Paul Jones had a love / hate relationship with his mellotron. He said it was completely unreliable and he never knew what to expect when it came time to play it at a show. It was either awesome or dreadful.

They were horrendously unreliable, Rick Wakeman ceremoniously burned two of his!
  
But there was nothing quite like it. I love the sound that dominated the bands I was into in in the early 70s. King Crimson, Yes, Genesis, Strawbs, BJH, Greenslade and a host of others.
 
That said its an odd choice of EZ Keys concept, for the most part it’s a sound for block chords and counter melody lines. I am not sure the MIDI would be useful. The market is quite crowded.
 
To date M-Tron Pro is the most versatile Mellotron emulation but Hollow Sun's Newtron Bomb II is the beast for real raw power. The updated Newtron Bomb III added a lot of refinements but I still prefer the earlier version.
 
I thought UVI Mello was pretty poor in comparison, as is the Tron Kapsul for Infinity player. I am reluctant to mention Sample Tron for fear of causing someone to start foaming at the mouth and falling over backwards.
 

Maybe someone came up with the name, than they just had to go an make it

You gotta love the name though - Mello-TOON.. Like TOON tracks.. Get it?  (I just crack myself up sometimes)

As much as I love my Trons, I do not need this one (already have several and M-Tron Pro).  I do wish TT all the best and hope they continue to bring innovative and creative tools and midi loops to the table.
