Well this is more of a idea than a request. I'm not entirely sure if others would feel the same way but to me i feel that a lot of the input level calibration/balancing scenarios would be easier and faster if there was a option to LINK the input/output controls on Nebula even if as a shortcut.
For example if i press and hold ctrl+left mouse click on the input fader/knob the ouput fader/knob will follow exactly but in the oposite way.
Say i hold ctrl+left click and drag the input hotter GAIN IN: 3.0163dB and the result would be GAIN OUT: -3.0163dB. I think it would make the task of proper calibration/balancing easier.
Also the benefit of using a shortcut like i said is that if one wishes to go the traditional way then just don't use the shortcut or otherwise just turn off the "In/Out LINK mode" in the MAST page.
better yet, like in voxengo plugins, also have a little box that indicates the RMS difference between the input and output so you can make them identical and get perfect comparisons with nebula on and off.
even having something 1/2 dB louder can give the illusion it is better. its VITAL to get this volume match right when selecting a program, esp something like a nebula preamp.
