Abstract
Abstract An acoustic data signal control system comprises at least one control data signal input for receiving polytonal acoustic control data signals, a control data signal store for retrievably storing received polytonal acoustic control data signals, a plurality of controls for controlling separate retrieval of selected segments of stored polytonal acoustic control data signals independently of the order and timing in which they were received and stored, said controls individually or collectively controlling performance of a chosen number of selected modifications on at least one selected parameter of a retrieved segment of polytonal acoustic control data signal, and at least one control data signal output for delivering the modified segment of polytonal acoustic control data signal to at least one signal generation or processing device concurrently with operation of said controls.
