Whoops, I actually meant Komplete's "The Grandeur". I made this a while ago and I just remembered that, whilst I started with Garritan, I switched to The Grandeur later on. Garritan is nice, (I've used it in previous videos), but one of the high F#s has a horrible tone. The Grandeur is good but needs a bit of work out of the box to make it sound "live". As for the MIDI, it was generated by Finale, then imported into Cubase where I manually edited it in an attempt to imbue more "humanity". Finale's Human Playback is quite good but will only take you so far.

@@tomekkobialka Thanks for your reply. I have tried Garritan Studio and I was not able to control it well enough to be substantially better than the Yamaha Disklavier Playback that I use with Musescore. I agree that the midi file generated by a music editing software needs to be manually edited (velocity, legato, pedals, ...). It is a very time consuming process that needs to be redone when changes are made into the music sheet. The built-in playback has the big advantage to allow quick changes into the music sheet.
