I don't notice the dust until the knob doesn't turn or screen can't be seen. I have a fairly high tolerance for this. All of my equipment in the studio accumulates the same amount of dust on knobs and surfaces regardless of manufacturer or materials.

Also, I don't have a MODX (I have a Montage). However, I'm not sure there's a big difference in the propensity to have dust accumulate.

None of these knobs have suffered operational issues from dust accumulation in the 6-ish years I've owned the instrument which travels from studio to practice to gigs. I have covers for equipment I rarely use but do not use them for my main board (Montage) due to frequency of use.

Jason, that is, I understand correctly that you do not have the same as I have on montage when using knobs? I use them with perfectly clean hands, in a short amount of time (literally, just turned 30 times and this problem arose).

Please write your opinion of those, who have MODX.

"I don't notice the dust until the knob doesn't turn or screen can't be seen." - I'm sorry, I didn't quite understand this sentence. That is, if you rotate the handle, dust appears? Could you reformulate this sentence? Thanks a lot in advance.

I'm saying, for me, my tolerance for dust is high so I don't notice it until it impairs my use of the product.

These are the same knob cap as on Montage. ZR050300

They have also been used for past generations.

BTW: my difference in tolerance for dust is just that - a difference. There's no right or wrong here.

... and I'd probably prefer the dusty knobs so I could see them better (higher contrast).

Thank you, now I understand you, sir. But my question to you is this, if you will: do you have the same dust as in my case, on your Montage knobs?

Bill, thanks for the detailed answer! Yes, I certainly made a mistake - of course, the volume controls are located left (I use Google translator, and apparently I was mistaken when I wrote). I looked at the volume handles in more detail - they are made of less porous and more dense rubber, although it does not seem to be obvious from afar. Still, I tend to the fact that the Super Knob and Assugn Knob material - really greatly attracts dust particles electrostatically (category B from your answer) - because I have all the factors leading to the formation and accumulation of electrostatic voltage (such as the carpet on the floor, etc.) - and when touching the smallest dust is instantly attracted to these handles. In addition, I also found several photos on the Internet, where Assign Knobs is also dusty (both Montage and MODX). This is not a problem of the tool, of course, this is the problem of the formation of an excess electrostatic charge indoor and, probably, high dustiness of the room. If I smear my hands with a moisturizing hand cream - the effect partially disappears (apparently there is an additional role, my dry skin is played - all dry microparticles + dust (for example, from playing on even a slightly dusty keyboard) instantly electrostatically appeared on the handles). Of course, keyboard materials easily attract dust electrostatically, because they are mostly all plastic - I think this is normal (although to be honest, I didn’t notice such a pronounced effect on other instruments - but perhaps I didn’t attach any importance). In any case, I love this synthesizer, and this little thing, which does not affect functionality in any way, can be easily forgiven (especially since the experienced member Jason explained that in his studio all instruments accumulate dust +/- in the same amount). Moreover, now the reason for this phenomenon has become clear.

Thanks everyone for your answers!
