Our Cylindrum library contains three separate variations of the instrument: dry small, dry fat and wet. The small set is made from a series of 1½-inch diameter PVC water pipes played by tapping fingers over one end, with a microphone positioned at the far end. The fat version is made from a series of 4-inch ABS corrugated plastic tubes with an open-ended rubber port hole, played with a ping pong paddle. Both sets were recorded in a dry studio room, giving them a full, resonant and fat tonality perfect for arpeggiated melodies and driving bass lines. The wet version is built from 4-inch ABS corrugated plastic tubes with felt mallets on a 3/8″ heavy rubber cap, recorded in an ultra-wide stereo array in a lush glass and tile hall. This slightly more distant sound and closed port delivers a much more brutal transient impact perfect for dramatic scoring and layering with other percussion.
