Hi, I dropped this message in the 6.05 thread in General.
Code:
I got it working(ish). This is what I did.
A factory reset to v3.1
An update to latest version 3.42
Set it to native/studio One mode
Disabled the Faderport in REAPER Preferences Midi Devices
Removed all of my surfaces in preferences
Readded it
Restarted REAPER
Restarted my FP
I'm not sure which of the steps made a difference...
Anyhow, Transport works, 3/5 Automation modes work, Solo, Mute, Arm and their SHIFT functions work, Fader works, the 8 buttons in the middle and their Shift finctions (Link, Pan, Channel, Scroll, Master, Click, Section, Marker, Lock, Flip, Lock (again), Zoom) Do not work.
Hope you get it working
