I have not used one.
I know for a while PGMusic sold one that (I think) sent the mixer changes (CC messages) as MIDI data which the programs responded to, but I'm not sure which ones may still do that.

Did you know you can record mixer changes in the Mixer window?
That way you do it once and save it.
Another thing that helps with the on screen mixer is using an ASIO driver; they are much more responsive time-wise to any changes.

Then there's the Nodes in the tracks view, but you have to b careful with those. You can end up creating a whole lot of data accidentally.
