Rain man theme - On Roland SC-55. I found this MIDI file online and I tried it out, and I thought I was listening to the original score at first :-), one of the best midi replications I've come to listen so far. Recorded through a small mixer, with a little eq on the bass, a tiny tad of analog reverb to blend it all together nicely but NO further post processing done digitally. I absolutely come to love the SC-55 in the 2 weeks I own it. If you look carefully, it actually automates between presets (Switches channel 3 from Pan flute to Choir Aaahs) automatically to save midi channels if needed. This is encoded in the MIDI track. Same goes for volume automation, panning and reverb / chorus settings.
