I have been highly critical of Arturia throughout the Keylab release. However, I bought it with the hope that it would be like Spark where the release would suck and that little by little it would be a great product. Well, the last firmware and software upgrades are doing just that. It took awhile, but I am now very happy with things. You have relative modes working, even with the faders! Scrolling now works consistently. The MIDI controls I have attempted to use are now working.
It took a bit of time ... But, thanks for keeping at it!
I just thought it was fair to come back and give Kudos after my other negative posts.
