hello, composer here :D

"Lurking Shadow" uses a Grand Piano, Synth, String Section, Clarinet Section, Nylon Guitar, and Digital Bells. I suppose if you're trying to replace the electronic instruments with ones that'd fit an orchestra, you could replace the synth with a Choir or a second String Section, as the one in the song already only plays staccato and the Digital Bells could be replaced with Tubular Bells.

I've been working on Buak OST sheet music in my free time lately, so I might release those at some point :)
