DSP optimization

Although MassCore automatically optimizes DSP allocation certain large configurations may still benefit from the
following DSP husbandry strategies.

DSP Saving

DSP saving modes can be found in the All Settings > Settings > Project > Mixer > DSP Power Saving page:
Player / Recorder mode
Transforms the mixer's full nodal matrix topology into a "diagonal" topology where only the direct paths are com-
puted (i.e. Input 1 to Output 1, Input 2 to Output 2, Input n to Output n)
This allows Pyramix to accommodate very large player/recorder Track counts (up to 128. It MUST be used with
Multiple Mono Mix buses.
Disable Punch in / Punch Out
is another DSP processing saving function that, as it name indicates, disables concurrent record stream manage-
ment whenever no Punch recordings are required during certain phases of a project's life. This might save another
couple of % of DSP load.
Disable Mixdown
is similar to the above. Disables concurrent Master outputs possible extra paths used for recording as mixdowns.
MassCore & VST Core Allocation
CPU Core Allocation
MassCore
MassCore can be allocated one or more cores for its exclusive use. If more it is desired to allocated more than one
core to MassCore, the optional SMP Key is required.
Projects with massive mixers can benefit from this but the chief benefit will only be felt with future developments.
Remaining Cores
By default Pyramix allocates all but one of the remaining cores to Windows as VST cores.
Example: Intel i7 4 core CPU (with Hyperthreading switched off ) where MassCore is installed and running.
• 1 core is allocated at boot-up for RTX/MassCore. This separation of MassCore audio processing and non-
real-time Windows environment functions is absolute.
• The remaining 3 cores are available to Windows as seen in the Task Manager
• Of the remaining 3 cores, Pyramix allocates 2 cores for use by VST plug-ins by default thus leaving one
core totally free for Windows.
• The 2 cores allocated for use by Pyramix for VST threads are still solicited by Windows and in essence are
simply multi-tasking both Pyramix VST tasks and anything else Windows needs to process, so the separa-
tion of audio processing and non-real-time Windows functions is not absolute, contrary to the case with
MassCore and Windows.
• The VST core allocation slider in Settings > All Settings > Hardware > MassCore enables the user to allo-
cate the remaining 3rd core, in exceptional circumstances, for extended VST processing power. The evi-
