Derivation in Cauldron took a pitched percussion performance, extracted midi, and then run the midi through 2 arpeggiators. This was handed to Pianoteq 4 that was loaded with Gene Ward Smith’s Cauldron tuning which is listed below. All things considered it is fairly musical for a semi-aleatoric composition.
