An array of universal processing elements (UPEs) may be interconnected through a switching matrix in response to control words which are in turn produced by a programmed digital computer in response to commands from a keyboard or a data file, thereby routing the outputs of selected UPEs to other UPEs for further processing and/or combining a sound stream in digital form. The matrix is comprised of both local and global conductors, the local ones being available to selected groups of UPEs. Each UPE is implemented as a digital multiplier, preferably with pipelining, and each UPE is comprised of a plurality of stages, preferably implemented with an adder for computing the sum of a plus the Boolean logic function [bxm+dx &upbar& m] and a multiplexer for forming the function [bx+dx &upbar& m], where a, b, d and m are bits of the respective two's complement number A, B, D and M, whereby the entire array of stages in a UPE computes A+[BxM+Dx(1-M)].
