okay i want to trigger my basedrum for some recordings
i got a external soundcard on my computer and needed to know if its not bad
for the card if i put the following trigger directly per 3.5mm line in into it.;

The trigger is acting as a piezo pickup in this case. It probably has an impedance mismatch going into your 3.5mm input which will most likely distort every once in a while. You may as well use your recorded/mic'd signal to trigger your sounds. Usually you need some type of trigger converter, a module. This takes the trigger signal, turns it into a midi signal and from there you can send the midi signal to your computer and do what you want with it.

i have an digital one
i just need the impulses...

So you're sending the digital trigger signal through an analog input?

its not a real trigger...
i just want to know if the 9volts can destroy my soundcard

Yes. Only an audio signal should be going into the audio in.

hm tested it
didnt destroyed
onlx made an selfbuild "pick-up"
