To begin I feel I have to mention that, while I did get information regarding recording and composition, I feel as if they did not answer my case entirely. So here goes:
I have been playing classical guitar for years and have numerous compositions stored on Sibelius that I would like to make more 'realistic' and 'listenable' as the music on Sibelius sounds unnatural. I know that I can plug my guitar directly into my PC (do I really need a preamp?) I don't know, however, how to convert my compositions for other instruments that I cant play, into actual instrument sounds as the Sibelius instruments sound extremely fake.
I understand that music maker software like MAGIX Music Maker exist, but does that mean I HAVE to buy a MIDI controller or can I import my Sibelius compositions to the music maker software?
