Pro Q2 Frequency Analyser
We've considered this, but it would start to look quite messy with input, output and SC spectrum both in L and R or M and S variations :-)
We'll rethink this though and see if we can come up with something smart...

Just, demoing the Q2 and thinking how cool it would be if the frequency analyzer showed two channels, left and right or M and S in M/S mode...
