Retrologue's knobs precision

in Retrologue amplifier’s envelope, the attack fader switches from 0 to 2 to 5 to 8 (ms)…
How to have the intermediate steps, 1 ms for example, without assigning the fader to automation track?
Thanks anybody.

I find that if you hold down the shift key, then you can drag the fader in 1 ms increments.

Hi Colin Park,
thanks for your answer, but, why it doesn’t work for me?
I’ve also tried with the sensibility of my mouse wheel…
Are you sure you’re talking also about amp envelope’s faders? Because other knobs work like that…

It doesn’t work with the scroll wheel. But it works if you drag the mouse up and down.
