Using a patch point and/or aux track should not be necessary. I use a send from my Master Bus to VU meters on my old Tascam frequently. If the send is Pre-Fader (Post button
not lit), the output level will
not follow the bus Volume control.
It
will, however, follow the bus Input Gain, and if you have LinkPFSendMute=1 in AUD.INI (default is 0), it will follow the Mute button as well.
