Claims

[Claims for Utility Model Registration] (1) A plurality of connected effect adding means for adding and outputting various effects to a digital input signal, and converting the digital input signal and the output signal of each effect adding means from a digital signal, respectively. An effect adding device comprising: digital-to-analog conversion means for converting into an analog signal; and analog addition means for adding up respective analog signal outputs of the digital-to-analog conversion means. (2) The plurality of connected effect adding means includes a former effect adding means that adds an effect to an input signal, and a latter effect adding means that uses the sum of the output signal of the preceding effect adding means and the input signal as an input signal. 2. The effect adding device according to claim 1, further comprising an effect adding means. (3) The plurality of connected effect adding means includes a delay effect adding means, a chorus effect adding means,
Utility model registration claim 1 characterized by having at least two reverb effect adding means
2. The effect adding device according to claim 1 or 2.
