   When using solo-in-place (SiP), in other words when soloed tracks are being
   listened to on the master bus, this fader specifies the gain that will be
   applied to other tracks in order to mute them. Setting this level to

+  −∞ dB will mean that other tracks will not be heard at all; setting to

+  larger than −∞ dB is sometimes called "Solo-In-Front" by other DAWs, because
   the listener has the sense that soloed material is "in front" of other
   material. In Ardour, this is not a distinct mode, but instead the mute cut
   control offers any level of "in-front-ness" that is desired.
