Dsp Saving - Merging Pyramix User Manual

of say 64 inputs by 64 outputs with a full independent multiply/add + individual delay on each matrix node on
what would be a 64 x 64 = 4096 nodes, while also taking care of all the other housekeeping tasks such as locking
with ultra low jitter to external clocks, managing time code, record streams, playback streams, not to mention pos-
sible FX such as EQ, Dynamics, Reverb, etc.
Note: Although MassCore automatically optimizes DSP allocation between the TriMe-
dia processor and the host CPU 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)
As one might expect, such a mixer topology optimization reduces the complexity of a 64 x 64 sized mixer from
4096 nodal computations down to just 64 computations, which is a dramatic DSP processing saving feature and
allows Pyramix to accommodate very large player/recorder track counts. It MUST be used with Multiple Mono Mix
buses. In Version 5 the channel count has been further increased to a maximum of 128.
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.
