Shostakovich's "2nd Piano Concerto," which he wrote for his son, 
Maksim (now a conductor), to play upon graduation from the conservatory. 
 
Sequenced for Proteus 2 Synths.   

 If you do not have a multiport MIDI interface, you'll have to combine 
two of the orchestral tracks (not hard to do) as there are 17 tracks.  
Note that on the Proteus 2 basses sound an octave lower, just like real 
bassed when they're played, so you may have to tranpose this track down 
an octave yourself if you use other equipment.
