From the Unsigned Podcast Network podcast:
3 software programs that will cost you nothing, nada, zilch.
DeeSampler. From Klaatus Dee Long, this program works with drum loops so you can edit, eq, and add fx. And it is 100 percent freehttp://www.deelong.com/deesampler.htm
Survey Werks has a program that integrates with your site that offers free surveys. The software can create a survey that can fit the color scheme of your site so it looks natural. It is free, but does limit you to 100 responses. They do offer paid services after that.http://www.surveywerks.com
Rebirth, the popular software that revolutionized synth emulation software and started an entire industry, is now free. Originally selling for about $300.00, it can now be downloaded via Bit Torrent from it's new site, the Rebirth Museum.http://www.rebirthmuseum.com
