Why does my pad lose notes during fast rolls?
Plug your kit in
Don’t guess, measure. The kit check is open to everyone and needs no account.
Check my kitA pad may respond perfectly to isolated strokes and then leave gaps as the strokes get closer together. In the MIDI stream, some fast notes simply do not appear. eDrumWork classifies this as D06.
The eDrumWork kit diagnostic uses a free burst at a speed you can play cleanly, instead of forcing a fixed fast tempo.
How can software see a note that is absent?
Without an external motion sensor, software does not know the exact number of physical strokes. It must not invent one gesture per metronome click. Instead, it studies the intervals between received notes.
In a steady burst, intervals cluster around a central value. A gap close to two or three normal intervals suggests one or more missing notes. A much longer deliberate pause is treated separately.
This cannot reconstruct the missing stroke with certainty, but it detects a break from the notes that did arrive.
Run a representative test
Play alternating single strokes for a few seconds at the fastest rate you can keep clean and steady. Do not speed up halfway through, and avoid deliberate accents. A series that is too short or too uneven should be reported as impossible to evaluate, not as healthy.
Check isolated strokes first, too. If notes go missing at slow speed, D01 describes the issue better.
Every correction has a cost
Protection against double triggering can remain active long enough to reject a genuine next stroke. Making it less restrictive recovers fast notes but may bring back duplicates.
Test both directions after each change: a burst for D06 and isolated strokes for D05. There is no universal value, and similarly named controls do not necessarily behave alike across brands.
eDrumWork detects gaps in the received sequence; it does not see the sticks or claim to count every physical gesture.
