This is a remix of Sonic 3 and Knuckles Hidden Palace Zone (Lava Reef Act 2). I used mostly triple oscillators and percussion samples to tell a story of urgency and tragedy.
I'm releasing the source of this in hopes that other LMMS users can learn from it. It only uses plugins and samples included with LMMS.
The original Hidden Palace theme seems to have 15-beat ostinatos. I had fun trying to find the most reasonable way to have 15 beats per section of the piece in LMMS.
