There was another Tunestorm challenge earlier this month, and in the finest tradition of such things, I threw together an entry at the last minute. The challenge this time was to make a piece using a sample taken from a spinning hard drive, which sounded just like a sine wave that slowly dropped in pitch.

You could use other sounds, too, but I chose not to — I loaded a chunk of the original sound in to a sampler (Specimen), ran it through some distortion effects, then through PHASEX, where I tweaked away on the filter in real-time using my Korg nanoKONTROL, and finally through some spatial effects. The result was some throbbing, unsettling ambient art-wankery that I call “pulse”.
