pax-eterna: I know it's frustrating, but don't take it out on the individuals here on the forum. I think the issue here is that the KeyLab community is EXTREMELY small. Keep in mind, Arturia is still a small boutique company run out of Grenoble, France. They're one of the few that are dedicated specifically to keyboardists and live performers. Live keyboardists (as opposed to DJs and beat makers), are like unicorns, and software-based keyboardists are even more rare. Put all those things together, and you have a very small group of people in the world that you're dealing with. That said, everyone who does post here usually really knows their shit, we're serious musicians. It may take some time, but people will respond, and as you found first-hand, with very useful information.
As for Arturia's lack of communication? Yeah, that's not good, as much as I love their products, they seriously need to step up their support.
