I can only repeat viewtopic.php?p=15037#p15037 and viewtopic.php?p=15037#p15037
There is no "magic switch" on the board which makes it work when you switch it.

Why did you change all 4 MUXers if only the kick input was not working?

Thank Dmitri
i built hihat pot pedal, but i cannot buy 25kohm pot, i replace by 20k pot and used 5,6 ohm resistor. I hear the sound of the hihat pedal under the sound of the other pad

after plugging it into the hihat pedal input and turn the switch to connect pin 3, it works very well but when i turn the switch to connect pin 5 (13 on the muxer) it's kick signal.

You've lost me again.
Is the kick input not working (as the name of the topic implies) or is the kick input false triggering?

Dmitri i so sorry but my english very bad , i cannot describe my mind a completely
i checked resistor 18 and diode bat 85 ( d9) and changed the MUXer, but jack 2( kick ) still not working.
this is the second board i did.
is Atmega reason this error ?

At the moment I cannot say what might be wrong because I still don't understand what you mean by "kick input is not working". Do you have somebody who can make a better translation? What is you native language?

My language is Vietnamese ( in the past vietnam received a lot of help from Russia ).... :D
i have has problem with input jack 2 kick input ( chanel 1 ), when i plugged pad or piezo, touch pad, piezo it's not working. LCD of MD not show signal.
I checked carefully. jack 2 to pin 4 ( 14 on the MUXer ) every thing is ok( jack, resistor 18, diode 9, and the MUXer)and i changed pad, the MUXer but it's not working.
I thing hardware is ok.

Then you definitely have one of these:
1. a break/short on this input.
2. R18 is much higher than 100 Ohm.
3. D9 and/or D10 are faulty or soldered with reverse polarity.
