So...what if each line had its own gain control? Just double click and have a knob....even better....have it be infinite gain and infinite negative gain....
The reason being...sometimes I have self-synthesis mulches that are super duper quiet...and I need to add 5 SGains to make it audible. OR, I have parts that are super loud...and I need to have an SGain set to just above negative infinity gain to unclip it.
So why couldn't the line itself have a gain setting? Default could be zero so it would be no change if you didn't want to use the feature.
I think this could be especially powerful in conjunction with the red/green lights on all the in/outs of contraptions...see a red light? just open up the line and dial it down a little. No need to cut lines and insert multiple Sgains or whatever.
