When crosstalk cancellation starts cutting your playing
Plug your kit in
Don’t guess, measure. The kit check is open to everyone and needs no account.
Check my kitCrosstalk protection can stop a tom from triggering a crash. Push it too far and it creates the opposite problem: when you really hit both elements, the module drops one of them. D07 is gone, but D09 has appeared.
The eDrumWork MIDI diagnostic tests both symptoms, so a setting cannot look like a fix just because it silences legitimate notes.
The false sense of success
If you retest only the source pad, the victim no longer sounds and everything seems fixed. But nothing yet proves that the victim still accepts a real hit played at the same moment.
This failure shows up in common combinations such as snare with hi-hat, tom with crash or kick with ride.
Build a reversible test
Choose one pair and always use the same order: A alone, B alone, then A+B. Repeat every step. A pair can only be evaluated if both elements responded reliably on their own.
After each module change, note the false events during A alone, the false events during B alone and the incomplete pairs during A+B.
Seek balance, not absolute silence
Aim for the least protection that removes the false note while keeping simultaneous hits intact. Depending on the module, the setting may be global, directional or per input. Do not assume that one brand or model uses the same direction and scale as another.
If both Note On events are there but you only hear one sound, the issue is not D09. Look at audio routing, choke settings or polyphony instead.
eDrumWork reports the tested pair, the missing element and how many times the problem was reproduced, so you can compare before and after on evidence.
