Who uses actuation set in 0.01mm steps? Fine adjustment on the HERO 84 HE

Competitive and rhythm-game players get most from the AULA HERO 84 HE's 0.01mm steps, tuning actuation to their touch. The range runs from 0.1mm to 3.4mm, so there are over 300 possible points. Typists benefit too, and Evetech covers the board for 2 years.

Who needs 0.01mm actuation steps on the HERO 84 HE?

A hundredth of a millimetre is thinner than a sheet of printer paper, so it is fair to ask who could possibly care about adjusting a key by that much. On the HERO 84 HE the answer is less about feeling each step and more about having room to find the exact spot that suits your hands. Fine actuation adjustment gives competitive players, rhythm-game fans and even careful typists a setting that fits them instead of a factory compromise.

Quick Answer

The AULA HERO 84 HE lets you place each key's actuation point between 0.1mm and 3.4mm, moving 0.01mm at a time. That gives 331 possible positions along the stroke. Competitive shooter players and rhythm-game players benefit most, because they tune for speed and consistency, but typists who rest heavy fingers on the keys can use the same control to prevent accidental presses. Evetech lists the HERO 84 HE at R719.

🎯 Who gets the most from it

Shooter players

Movement keys in a shooter reward a short, clean press. Many players set a shallow actuation point on W, A, S and D so a strafe starts with the lightest push, then pair it with Rapid Trigger so the key releases the moment they lift. Fine steps let you edge that point shallower until it starts misfiring, then back off a touch. A coarse board forces you to jump past the sweet spot.

Rhythm-game players

AULA singles out rhythm games on the HERO 84 HE page, noting that Rapid Trigger resets keys the moment you lift for continuous triggering. Streams of fast repeated notes are exactly where that helps: the key does not have to rise all the way back before it can fire again. Fine actuation lets a rhythm player match the depth to their tapping style, which varies a lot from person to person.

Typists

Typing is not about speed of release; it is about avoiding errors. A light switch like the Black King, at 33gf, can register keys that a resting finger merely leans on. Setting a deeper point on the home row stops those stray letters, while keys you want quick, such as Backspace, can stay shallower.

🔧 Where and how the steps are set

You set actuation through AULA's browser-based driver; a Chromium browser on either Windows or Mac will open it. Settings apply per key, so one board can carry several depths at once.

A practical way to tune it:

Start every key at a middle depth and use the board for a day.
Adjust only the keys that annoy you, in small moves.
Change one group at a time, such as movement keys, then the number row, so you know what made a difference.
Note the values that work, so you can restore them after experimenting.

🤔 Is finer always better?

Not on its own. No finger can repeat a movement to within a hundredth of a millimetre, so the benefit of 0.01mm steps is the choice they give while tuning, not a speed you feel in play. Other things shape the experience more:

The switch itself, including its 33gf actuation and 53gf bottom-out.
How you pair actuation with Rapid Trigger.
Whether you use the two-actions-per-key tools in the driver, Mod-Tap and Dynamic Keystrokes.

The HERO 84 HE also reads its keys quickly, at 48kHz across the board, and reports at 8000Hz, so the controller keeps up with whatever depth you choose.
