9. Appendix: Sound engine
The Sound engine resources used for one voice in the Poly Voice Area of the active patch is shown in the
PVA Load indicator on the Editor toolbar. The Load cannot exceed 100%, i.e one voice in a patch can
never use more than 100% of one Sound engine. The only way for a patch to use more than one Sound
engine is when it comes to adding more voices. Adding voices in a patch is simply the same thing as add-
ing exact copies of the module setup used for one voice in the Poly Voice Area of the patch (described in
the picture above).
When you load a patch to a S
optimizes the usage of the Sound engines. When this recalculation is performed, the outputs will be mute
for a brief moment. During the calculation, Nord Modular distributes the voices of a patch among the
four Sound engines, starting with Sound engine 1.
The voice assignment is a bit different depending on if you use only one patch or several patches. This is
described in detail below.

This example shows how the Sound engine resources are distributed when you have loaded the single
patch described above to a S
exists. The patch in our example uses a PVA Load of 21% and a
difference between the Load and the PVA Load, in this case 34%-21%=13%.We have requested 4 voic-
es, and no other patches are loaded into any other S
Sound engine 1
Our 4-voice patch fits nicely in one single Sound engine.
The Nord Modular system always start by distributing the PVA sections (voices) and then finally the
CVA section. A voice area of a patch cannot "overflow" from one Sound engine to another - it must al-
ways fit "in one piece" in one Sound engine. If you request more voices than what will fit in the Sound
engines, the distribution of the PVA sections continues until there is enough room for the remaining
CVA section of the patch. In the example above it should have been possible to request, and get 16 voices.
