Hi,
same issue here.
Bought a Keylab 49 from Amazon, just unboxed. Looks great. Perfect connection, firmware updated, perfect communication with Midi Control Center and Analog Lab. But...
While some keys worked perfectly, some others couldn't feel a soft touch. I've shot a video.
I've asked Amazon to replace the keyboard. They've been great, quick replacement.
Unboxed the new Keylab, tested, same issue (on different keys). I've shot another video.
2 bad Keylab 49 out of 2 isn't a good performance imho. No response from Arturia so far.
I'm waiting for the third Keylab 49 from Amazon. Cheers
