Mozart - Piano Concerto No. 23, Andante/Adagio [piano + synth]

Piano Concerto No. 23 K. 488, 2nd movement: Andante/Adagio in F-sharp minor by Wolfgang Amadeus Mozart (1786). The original is piano solo vs orchestra. I’m trying to do it all live in one track with the piano and some synth. The instrument is a Clavia Nord Stage 2 using a sampled Bösendorfer grand piano and some sampled Mellotron flute and a synth pad.
