This is fantastic. Thank you so much for the effort you put into this. My new Faderport works perfectly with LPX now.
Tip for new users: Make sure you use a somewhat older computer with a USB2.0 port to update the firmware on the Faderport. I can confirm that updating does not work on a macBookPro with USB3.0 ports. After updating the firmware, the faderport works great on a USB3.0 port directly on my MacBookPro. It does not seem to work well via my USB hub.
Again, thank you!
