Hi
I just noticed a little strange sound artifact & I had problems with my unit a while ago. Sometimes there are some clicks happening, and I noticed that when I change the filter type on the filter page there is a crack happening at every change, it it normal?
Thanks
Mine doesn’t do that, you might unfortunately have a problem with your unit.
Thanks
i am so disgusted, i have live shows coming in july and september, I can’t send my unit back as I fear 3 month without it…
thanks anyway
while sound is playing? yeah i can get clicks switching filter types.
Yeah, same here. Guess thats normal when sound is passing trough, because certain frequencies get cut out or come in rapidly.
It should not make those clicks with no sound though.

When I first responded, it was from memory because I had not noticed the issue. When I’m doing sound design I usually have an idea about what frequency range I’m trying to isolate so I don’t really switch filters while the sound is playing. So I went and checked mine, and it makes no sound when switching filters as long as there is no sound. There is a very quiet, popping when switching filters while holding down a key. It is generally quiet compared to the sound though. When switching to a drastically different filter type, like LP1 to BS or HP2 to BS is the sound really noticeable. The pop is quiet when switching from similar filter types like LP1 to LP2. Also, when switching types very quickly the popping becomes more pronounced.
It’s still not an obnoxious sound though, it’s kind of musical, like a micro kick drum. This was with a default saw tooth init patch. If your results are the same I suppose it’s normal, but if that noise is really loud or happening when the sound is off you do have a problem.
I also programmed a sequence and P-locked different filter types. There was no popping as long as the notes didn’t overlap. I programmed a basic 4x4 sequencer and anything below a note length of 4 was fine. At 4 the notes were overlapping and a pop became apparent.
Sort of sounded like IDM. 
Thank you all for all these valuable answers
I was worried with these clicks that seems also to happen at the end of the phrases when using delay/reverbs too on certain filter configuration. I am planning to record a disc using A4 and other gear but A4 as the main part of the music ( i wait the overbridge plugin to do the record) and i wish I won’t have theses clicks, however this is an incredible machine, the best I ever owned.
Most synths will make clicking sounds if you change the parameters very quickly while a note is playing. P-locks, sample locks, and sound locks on the Elektron gear allows you to radically change sounds almost instantaneously, so that can result in clicks similar to using rapid automation changes in a DAW.
So, you just have to decide whether it bugs you or not. If it does, then you need to get creative in thinking of a way to work around it. 
That’s probably one of my favorite aspects of using the A4, actually.
Those clicks are expected for me.
Workaround are just all around other parameters.
Switching filter type during a sounding sequence is something that has to deal, somehow, with Glitch and friends, IMO.
Furthermore, it’s more noticeable when happening to a source that is feeding an Fx like reverb, because the reverb replicate, bigger, that click.
One fun trial i would do now is to play a sequence where fast 1/16th or longer Filter Type p-locks (read: clicks’n’shitz) going to Chorus with quite extreme tonal settings.
Don’t why…i am just imagining strung metal fluttering
yeah, i expected and use the clicks. i wouldn’t mind a sweepable multimode at some point tho. …but i’ll have to listen more closely the next time i parameter slide filter types…
you might try experimenting with making a "sound"that doesn’t make sound and lock that right before the new sound, like a “note off” or making the release phase of the sounds shorter.
