Yamaha 01V + Steinberg UR22C

Hi there!

I am using a Yamaha 01V to control my DAW Cubase LE AI Elements 9 thru a MIDI connection on my Steinberg UR22C.
So far when I am using AUDIO tracks the motorized faders, Mute + EQs control works properly, as stated by the manufacturer when you use de 01V as a controller. The problem comes when I load a VST track, the mixer does not recognize them. Just AUDIO tracks.
Do you guys have an idea what might be the issue?

Thanks a lot in advance.
