A short loop i did with a sample from a moog minitaur. The sample was downloaded from modular samples here on free sound. The loop was created in metasynth.
Sample made in sfxr with layered sawtooth waves in harmony and sliding highpass and lowpass filters, then used as a note in sfozando to create an uneasy melody.
Heavily time-stretched sample from a micro-korg synthesizer where the wavelength and tempo were being tweaked on the fly. Remember kids: winners don't do drugs.
