What a trip.
Nice work, although this might be too adventurous for this particular community. :) Which free programs do you use, exactly?
Thanks, I'm glad you liked it. I've been playing around with sounds a little bit, and I've really just been trying t find my own sound and style, so there is still a bit of an unprocessed feel to it I think.
As for the software, I used Audacity for all of my music because it allows me to build basic sine, square, and saw waves, and allows deeper control of audio samples. I also use various iPod applications via a line-in connection for more complex sounds. I've used lite versions of NLog Synhesizer, Virtuoso Piano, and Hammerhead drum machine, as well as Speak EZ, which is completely free.
