“Riverrun” is entirely realized with the method of sound production known as granular synthesis implemented on the author's PODX system at Simon Fraser University in Burnaby. With this method small units or “grains” of sound are produced, usually with very high densities (100-2000 grains/sec), with each grain having a separately defined frequency and duration. All sounds in this piece were generated with real-time synthesis by the DMX1000 Digital Signal Processor. Considerable use was made of ramps applied to the synthesis variables; that is, parameters were made to change over time. BT
