This is my very first effort with MIDI Orchestration...

Wolfgang Amadeus Mozart: Die Zauberflöte (The Magic Flute), K.620 (Singspiel)

Quite effective sounding Larry, I do wonder if the Piano's stereo image is a little too wide.  When the bass notes of the piano came in it felt like there was hole in the middle of the piano sound.  All in all nice job the mix sounded and felt balanced, it had some feel as well so it did not sound completely midi'ed.
 
Thanks for sharing.

2 Separate pianos Wookie...

I used Mirsoslav 2 on most of the this...

The Left Piano is Philharmonik Grand
And the right Piano is Studio Grand...

Thanx for the kind words...Now I know what these "Orchestrators" go through!!! 

OK that makes sense then Larry, still a little wide for me personally though.  Perhaps use some Mid/Side processing to create two virtual positions in the sound-stage, giving the feel of two different pianos.

Wow Larry, this is very nice. Really good for your first Midi orchestration!! I also thought the piano (being somewhat the main instrument) would benefit from being centered as the other instruments are already spread. Other than that, great job brother!!! 

MIDI is one of my major nemeses.  From my perspective this is very good, especially for a first attempt.  Terrific job.

Ok...took Wookie and Mesh's advice and did a few more tweaks...
