With the exception of the Recording Studio, Mac OS X workstations in studios have the RME HDSPe AIO interface.  See the Routing Diagram to understand how the interface connects to the mixer and monitoring systems.

There are three connection paths between the workstation and the mixer:
  1. Stereo Analog (to mixer only): for simple stereo playback.
  2. Stereo AES/EBU (digital to mixer only): for 2 channel 96kHz playback.
  3. 8 Channel ADAT (digital to and from mixer): for multi-channel I/O up to 48kHz.

  1. Start by recalling the CCRMA DEFAULT mixer setting on the Yamaha DM1000 digital mixer.  This will set up all of the connections listed above.  For this example, assume 48kHz sampling rate (a standard setup in the studios). 
  2. Verify Audio Midi Setup settings in OS X:  Open Applications > Utilities > Audio Midi Setup.   Make sure that the HDSPe AIO interface is selected for input and output and select/verify the proper sampling rate (48000).  [screenshot: proper Audio Midi Setup]
  3. The HDSPe Settings and HDSPe Mixer programs should have opened automatically when you logged in.  If not find and open them from:  Applications > HDSPe Settings/Mixer.  
  4. Verify two parameters in HDSPe Settings: Sample Rate: 48000 Hz.  Clock Mode: AutoSync.
  5.  Keep HDSPe Mixer open and visible to see levels.
  6. Open the HDSPe Mixer routing matrix:  HDSPe Mixer > View > Matrix.  If it's the first time opened, the default output is a diagonal (one-to-one) mapping.  [Matrix default image] This default mapping works only for Stereo Analog output.  ADAT and AES/EBU will not play sound without additional configuration (see below).
