Hi i have one question related to my mixer analog,.i dont know is this a problem or i am doing something wrong,.when ever i press fx button on or off i hear a pluck noise sound ,.its very noticeable so every time i use effects i know where in position of the mix i have use them.

A guess only here it's the electrical signal sent, probably nothing much you can do (may be a bad contact that interferes eventually). Comes down to the quality of the hardware I think. Once again only a guess.

thank you for reply ,.yes something like that (ZAPpp sound = On/Off) even when my parameters on bpm counter are correct ,very irritating
