Greetings,
One of my pads of my mashine micro is not responding. I get no sound of low sound when I press the pad. What can I do?? Is it defect? or dirty??
It could be both.
There are some threads here on the forum about opening and cleaning things.
D-One seems to be the one with more experience (he even have a video showing some passages)
Make a search here in the forum writing “cleaning pads” and filtering with D-One as Author and you’ll find many threads where he gave many suggestions.
The bottom left 2 pads of my MK3 weren't registering full velocity anymore but after a cleaning with the help of the video in the post above they're as good as new again. It's not difficult, just take your time and be mindful.
