ABSTRACT:
A method and a system for rapidly attaining a large number of different sounds in an audio signal processing system. A preferred embodiment comprises an audio signal processing system which includes a main housing, containing a main circuit apparatus, cartridge-receiving recesses, and cartridges fabricated to be removably received in the recesses, each cartridge containing an audio effects circuit which affects the signal in a unique way to provide a different sound output. A plurality of electrical contacts of the recess and cartridge respectively provide disengageable connection of the audio effects circuit to the system. In order to avoid the generation of spurious signals into the main signal path during the changing of a cartridge, and to maintain the uninterrupted flow of the main signal path through the system, switching means are connected such that the audio signal is noiselessly routed: flowing either to and from a recess via and through a cartridge therein, or passing by the recess to the next recess. Switching means are further provided for maintaining the continuity of the audio path while the recess is empty. The cartridges are inserted and removed producing, respectively, in the audio path, the quiet appearance and disappearance of the effect of its audio effects circuit. Panel-mounted switches and foot switches are provided to command bypass of any or all recesses whether said recess is devoid of a cartridge or contains a cartridge fully or otherwise installed therein.
