Streaming digital audio between applications

Procedure

  1. Create input and output busses in both applications and route these to the digital inputs and outputs.

    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”.
