Abstract
When a plurality of effects are simultaneously applied to an input audio signal, a plurality of effect-algorithms each for applying solely an effect to the input signal are stored in a memory, and a plurality of combination-algorithms or combination-data which represent combinations of the effects and orders in which effects are applied to the input audio signal are stored in the memory. When one of the combination-algorithms or the combination-data is selected, effect-algorithms included in the selected combination-algorithm or combination-data are selectively read out from the memory. A program for applying effects in a predetermined combination and order is written by CPU based on the read out effect-algorithms and combination-algorithm or combination-data. Receiving the program, DSP successively applies effects to the input audio signal in accordance with the program. As a result, the present effector needs less memory capacity than the conventional effector in which a number of programs consisting of combinations of effect-algorithms are previously stored. A multi-effector comprised of a connection of a digital effect adding device and an analog effect adding device, is provid…
