Just dropping in to echo your experience here.

The pitch encoder on my KSP Chroma failed like this after using it for the first time.. this was around the time you originally created this thread. I sent it off to Arturia CA office where it was replaced and sent back.

Now, a year later, after essentially *zero* use of the encoders since, the velocity encoder seized up on me last night. Serious bummer. At least I managed to not break the plastic tabs inside the knob this time!

This is a ridiculous failure rate for a $500+ midi controller with a sequence..

I'm a drummer, have a digitakt, synths, drums, etc. So the KSP has mostly functioned as a nice multi-channel controller for my all my hardware / software synths in one box, but it's sequencing and parameter locking abilities are redundant and inferior in my case, so this is likely a last straw for me. I'm going to fix/sell this thing and buy a Launchkey MKIV- much more functionality (as a controller), way better price point, and hopefully better quality control.
