This is very cool. To think there is a piece of software (Audacity) in my wife's computer that we downloaded for free with the sole intent of getting some old songs on my BandMix profile, and then realizing that we have the means to produce decent sounding NEW compositions with very little hardware and a little bit of creativity.
Scarlet,
It seems that we may be in the midst of a new wave of musical expression. I like your "poor man's synthesizer playing"! Seems like a growing trend around here lately to do a whole lot with very little. technology is a wondrous thing indeed.

I'll make it a point to check out these other fine examples of musical freeware.
