I'm running Sigma Studio Ver 3.11 BUild 1. Rev 1356. And I have a 4 input, 3 output mixer. My assumption from reading the literature is that the inputs are represented by the rows of controls, while the outputs are the columns creating a 4-row, 3-column mixer board. My issue is that when I set up the first row (input) for the desired outputs, and set the remaining three rows (9 controls) to -200dB, I still get bleed through from the inputs that are effectively turned off. I proved this by inserting mute blocks into the input lines and muting them and my bleed through signal disappeared. Is there an issue with this control, or am I misunderstanding something?
