This spectrogram was produced from a clip taken from a recording of One Drop is Enough given to us by its composer, Helge Krabye (pictured below). Some of the Metasynth graphical "presets" used by Helge Krabye, i.e. graphical synthesizing code used by Metasynth, are shown below as well.
We gratefully acknowledge Helge Krabye for supplying us with his recording of One Drop is Enough, as well as the photos above. You can find some great videos of Helge Krabye's compositions at this link: Homeless Balloon on YouTube; and purchase his recordings at this link: Homeless Balloon on Bandcamp.
