In the mixer, you can adjust the ratio of dry sound to wet sound, bypass the effects, and mix the effects into serial or parallel groups. By default, mixed effects are in the form of serial groups, in which signals are transmitted directly from the output of one effect to the input of the next. In parallel grouping, each effect receives dry sound independently, and the output effects are mixed at the same level.

Click the "serial" or "parallel" option in the mixer, and the mixing settings will automatically switch to the above options. In the case of continuous grouping, the effect input is 0% of the source effect (specified in the source text box) and 100% of the previous effect (specified in the previous text box). At the same time, except the last adjustment button is set to 100%, all other effect output adjustment buttons are set to 0. When grouping in parallel, the input effect is set to 100% dry sound source and 0% previous effect, and the effect output adjustment button is set to the same level (3 effects are set to 33%, 4 effects are set to 25%, and so on).

Note: The first effect in the mixer has no source effect and previous effect text boxes, because there is no previous effect in this case.

PS: pure human translation. I don't know whether some technical terms are accurate or not, but there should be no big problem with their meanings. I hope it helps you.
