Buses
In a MassCore system the only limitation on the number of audio I/O buses is the available power. For now the
maximum number of buses is artificially limited in code to 512 (at 1FS, 256@2FS, 128@4FS, 64@8FS).
The Pyramix Mixer uses a number of different types of Bus:
General Mixing Buses Sum audio and are available in several types. (see below)
Control Buses Do not carry audio. There are two types; the Panning Control Group and the so-
called VCA Group.
Object Buses These are a special type of General Mixing audio bus provided for new 3D immer-
sive formats including Dolby Atmos.
Internal Return Buses These are a special type of Bus used to return the output of General Mixing Buses
back to Input Strips.
General Mix Buses
General Mix Bus Types
Mix Bus Master Output Buses. May be routed to physical outputs.
Mix Group Used as a Sub-Group principally for Effects, e.g. reverb. Can only be rerouted into
another General Mixing Bus.
Aux Bus Used principally for artist foldback. May be routed to physical outputs.
Aux Group Used as a Sub-Group. Can only be rerouted into another General Mixing Bus.
Note: Please be aware that a Mix Group Bus or Aux Group Bus will auto-take Internal Bus con-
nection resources, starting from the last one. E.g. IB384-IB385 for the first two Group Channels
added to a Mixer. This means that you will no longer see IB384 and IB385 in the IB list.
General Mix Bus Features
General Mixing Buses can have a virtually unlimited number of channels. (Only limited by the maximum sup-
ported by the Pyramix engine.
Each channel can be assigned a type, including 3D specific types, from the extensive list of Channel Types. Please
see: Channel/Speaker Types on page 264
When creating a new General Mixing Bus, (Right-click context menu Bus > Add > New General Mixing Bus) the
choice is given for one of the five types, the number of channels and a choice of predefined Channel Types (AKA
Speaker Arrangements e.g. Mono, Stereo, 5.1 Dolby, 9.1 Auro etc.) or Custom. (Please see next page)
General Mixing Busses can also be given an optional Room Size. In this case the panning algorithm changes to a
distance based algorithm. Please see: Room Models on page 208.
An existing General Mixing Bus topology can be modified after its creation by using the Room Editor. Please see:
The 3D Room Editor on page 263.
