I bought mine two years ago and I must say it greatly improved my workflow. I use the fader, which selects your selected audi/midi/VST channel automaticly all the time.
The problem is that in Cubase 9.5 and Nuendo 8.3 the selection of the VST-Outs is broken. You can select it, but when you select a midi channel or
an audio channel afterwards, VST out is still selected, so CC121 is stuck with the values of this VST Out Channel and doesn’t switch to the values
of another channels anymore.
Here is the discussion I had on Cubase Issues Subforum.
Martin Jirsak confirmed the issue. Steinberg is aware of it but it’s unclear if and when they are going to do something about it.
In Cubase 9.0.4 everything works as expected.
If you are not working with VSTs I would highly recommend it. If you are composer working with Midi and Multi-Out VSTs I will wait untill
the issue is fixed.
Update: The track selection issue is fixed in Cubase 10.0.15, Cubase 9.5.5 and in Nuendo 8.3.2
