Activating VST System Link
The number and configuration of the busses depend on your audio hardware and on
your needs. If you have a system with 8 digital i/o channels (such as an ADAT connection),
you could create several stereo or mono busses, a surround bus together with a stereo
bus, or any combination you need. The important thing is that you should have the same
configuration in both applications – if you have 4 stereo output busses on computer 1, you
want 4 stereo input busses on computer 2, etc.
2. Set things up so that computer 1 plays back some audio.
For example, you could import an audio file and play it back in Cycle mode.
3. In the Inspector or MixConsole, make sure that the channel containing the audio material
is routed to one of the digital output busses.
4. On computer 2, open the MixConsole and locate the corresponding digital input bus.
The audio being played back should now “appear” in the program running on computer 2.
You should see the input bus level meters moving.
5. Reverse this procedure so that computer 2 plays back and computer 1 “listens”.
RESULT
Now you have verified that the digital connection works as it should.
NOTE
From this point on in this chapter, we refer to the busses connected to the digital inputs and
outputs as “VST System Link busses”.
Settings for the audio hardware
When you exchange VST System Link data between computers, it is important that the digital
information is not changed in any way between the programs. Therefore, you should open
the control panel (or additional application) for your audio hardware and make sure that the
following conditions are met:
If there are additional “format settings” for the digital ports that you use for VST System
Link data, make sure that these are turned off.
For example, if you are using an S/PDIF connection for VST System Link, make sure that
“Professional format”, Emphasis, and Dithering are turned off.
If your audio hardware has a mixer application allowing you to adjust the levels of digital
inputs and outputs, make sure that this mixer is disabled or that the levels for the VST
System Link channels are set to ±0 dB.
Similarly, make sure no other forms of DSP (pan, effects, etc.) are applied to the VST
System Link signal.
Notes for Hammerfall DSP users
If you are using RME Audio Hammerfall DSP audio hardware, the Totalmix function allows for
extremely complex signal routing and mixing in the audio hardware. This can in some situations
lead to “signal loops” in which case the VST System Link will not work. If you want to make
absolutely sure this will not cause any problems, select the default or “plain” preset for the
Totalmix function.
Activating VST System Link
Before you proceed, you need to make sure that VST System Link is set as the timecode source
in the Project Synchronization Setup dialog and that the desired sync options are activated.
After setting up the inputs and outputs, you now need to define which input/output will carry the
actual VST System Link information.
