Yesterday I discovered this awesome directory of Chiptune samples, continuing my quest this morning I ran across this post on 8bitcollective detailing a number of VST plug-ins that emulate and recreate classic chiptune sounds! Many of these plug-ins are free, so you can download them and load them into your favorite music making program and start chipping out! I made this piece last night with The Magical 8bit Plug-In. Wow there are a ton of links in this post.
