Hi,
I haven't still used it but seems interesting:



You can grab it here: Panipulator 2.

 

Thanks for the info, seems a useful tool.

btw it's always better to check mono-compatibility on a dedicated mono speaker
though this will come in hand for that too, for checking L and R separately. Nice the different levels available on the mono sum too.

Said that, "I talk the talk but don't walk the walk", as right now I don't even own a pair of decent stereo monitor, let alone the mono check (f*ckin money).
