This has popped up a few times on the forum. Arturia claim to have fixed in the latest 1.2.4 firmware. I certainly can’t get it to stick, so fingers crossed.
So happy to hear this! I have followed (and posted on) the thread you started on the Arturia forum. I haven’t had time to try this myself, but I am excited about this. Except for this stuck notes issue, I have always loved this keyboard. Thanks for posting the update!
