MR816X and Cubase 7.5.10 control room meter.

i think it shows only the “Default output” level (and the control room -monitor if activated )
in vst connection window go to outputs tab- the output colored orange is the default output, u can change it by right click on other output and set it to default.(also all mediabay ,vari-audio etc auditioning sound will go to default output or control room if connected)
