Mutes

Each of 4 channels has a toggle to soft mute the incoming signal, as well as a button (inv) that momentarily inverts the value of the toggle for as long as it is pressed. There is also a master play toggle, which mutes all the channels at once when off, and a master invert button that momentarily inverts the values of the toggles in all the channels.

The down arrow buttons next to the inputs allow you to send the signal of that input to the next channel, and this works regardless of whether the mute toggle for that particular channel is on or off.

Great for quickly muting signals during performance, as well as for making submixes and momentarily switching between them on the fly.
