Just recently recieved my new Kontrol S88 Mk3 keyboard and have only been dealing with issues with this thing. Currently, this keyboard is nothing more than a $1400 paper weight.
The main issue is with the firmware update (without which, the keyboard is completely useless), receiving the message "your kontrol s mk3 failed to boot into firmware and update mode […]", on every attempt. I've tried every possible solution provided on the NI troubleshooting guide regarding the issue to no avail.
From what I've gathered, this is a Windows driver compatiblity issue that many other people have been facing since the release of this product with no solution other than doing some shady driver editing apparently.
I have contacted support and have not had a reply in 24 hours.
I cannot request a return on the product since the link is missing from the order history page.
If anybody knows a practical solution to this please let me know, thanks.
