The first patch, “Infinite Pads” contains a glockenspiel and “knock on wood” samples highly altered using “Paul’s Extreme Sound Stretch.
“Metal Resonant Drum” contains samples of kitchen pots hit with a spoon, a fridge door closing and other kitchen stuff, all recorded with a contact microphone and a portable recorder.
The last patch, “Wine Pads” derives from a recording of a red wine Cristal glass. The glass was tuned carefully and contained real Italian red wine.
All those patches were all used commercially as part of sounds for scoring a library music track and are now released free of charge and licensed under a Creative Commons Attribution 4.0 International License.
