Here's some songs I made with Acid back in 2006, and since the Audio mods don't allow songs made out of loops; I decided to upload them to my dump.

Warning: this is a huge download, but I had to get these off of my chest.

Tests I did with the Synth1 VST:

As for LMMS, I have made quite a few projects, but only a few were actually decent. Plus, they're in .ogg format, so they require music players that support that format. They'll be added when I get the chance.
