Sensitivity Tuning Guide
How to use the 4 sensitivity knobs to remove ghost notes and missed inputs. Most issues can be fixed in about two minutes once you know which knob does what.
What is a ghost note?
A ghost note is an input the drum registers that was not played. It usually comes from cross-vibration (hitting one side triggers the other) or from sensitivity set too high. The opposite problem, a missed input, means sensitivity is too low.
Knob layout (D / J / K / F)
| Knob | Controls |
|---|---|
| D (1st, leftmost) | Left KA (left rim) |
| J (2nd) | Right DON (right face / centre) |
| K (3rd) | Right KA (right rim) |
| F (4th, rightmost) | Left DON (left face / centre) |
Turn counter-clockwise to increase sensitivity and clockwise to decrease it. Adjust in small amounts: a slight turn has a large effect.
Tuning steps
- Open a test chart or the simulator's input test.
- Play steady single DONs on each side and watch for any KA registering. If one does, lower that side's KA knob.
- Repeat with KA hits and check that no DON registers. Adjust accordingly.
- Play a fast roll. If notes drop, raise sensitivity slightly. If extra notes appear, lower it.
- Re-test until clean on both single hits and rolls.
Software tuning (legacy models)
Older (legacy) E-Box models used a PC Setting Program for tuning. Current White E-Box models are tuned entirely with the 4 hardware knobs and need no software.
To change to Nintendo Switch mode (White E-Box), hold the “+” button when connecting. The manual has the full connection steps.
