Hi, I've accidentaly found a possible bug in the Classic EQ M/S function.
It acts exactly like L/R. It doesn't happen in other TR5 EQs . Just take any stereo track and select Mid/side on the EQ, lower the volume of the side, you get sound only from the left speaker. At least that's what's happening to me. Tried it with other EQs from the suite, it works as it should.
