The "heart" of the bx_solo M/S tool are the unique SOLO BUTTONS that allow you to actually LISTEN to all components of a stereo mix / stereo signal individually: L(left channel), R(ight channel), M(ono sum) and S(tereo difference signal) - and all this PHASE CORRECTED (when needed) and mono-ed out on BOTH SPEAKERS of your system.
bx_solo is very helpful when working in M/S modes (because especially listening to only the S-signal of a stereo mix is not so easy to do with modern DAW stations) and to check your signals / mixes for errors, clicks, noises, whatever.
bx_solo also contains a STEPPED M/S STEREO WIDTH CONTROL, so you can get an impression about what you can actually do with it. Do try it out on subgroups (makes ROCK GUITAR subgroups jump out of your speakers at about 150% !!!), FX returns, keyboards / samplers, etc.
