I posted this message on OP-Z bugs topic, when I found this topic which is more specific. I’m sorry for the duplicate message, but I think I’ll find a better answer here.
I have a last batch OP-Z unit with the new icons, and I have some retrigger problems mainly with two white keys. In general, it works fine, but sometimes the keys retrigger when the key is released. After testing these keys, I think that the pressure to restore the key to the normal state is less than other keys, just a little bit lower, and it happens mainly when it’s released slowly, or because when you are pressing keys fast, sometimes I don’t press the keys with same pressure when playing live. The keys that have this problem are located around the middle of OP-Z, the white keys between the black keys 3 and 4.
Is this the same problem with the first batch of OP-Z or was the problem with the first batch even worse? I don’t know if I have a defective unit or not.
