Which kernel is this?
I'm using Ubuntu 14.04 with rt kernel, and tweaked for recording
And minilab works (with some issues) with amsynth, qsynth, lmms, jack...
But it won't let me assign the pads... i'd say it works like 60%
Arturia should give the users the drivers (musicians don't have anything to do with those contracts they use to channel their money - we bought the product, we're not asking for a favor. Its our right to use the device properly where we want to).
