Looks superb. I can't test it because my RME does not support it. I also don't get this information in the manual.
Is it possible to have a low shelf and a low cut in combination?
Sometimes it's good to limit speakers at night or to simulate smaller speakers when you have full range speakers. A broad low shelf is helpful to add add or remove a bit of lower frequency to taste.
I see 3 filter type buttons, but I have no idea what's available behind them (especially the one on node 8) the and if all filters can be be freely placed in the spectrum (20-20k). Some eqs can't move nodes of the upper frequency range to the lowest frequency for example, like when you can't set a lower frequency than node 3 has for node 4.
Do I see it correctly that you can delay the left and right channels individually?
Some idea. What come to my mind is an equal-loudness curve function. You would calibrate a volume of 85db my measurement and set it as the reference point. And from there on the curve is adapted by the change of the volume in total mix accordingly.
How do you think about tilt filters for small taste adaption of the spectrum without introducing too much colouration?
