NORD MODULAR G2 V1.4x 10. Technical reference: Calculation order for the modules
Page 139
extra End output on the ADR module takes an extra 0.8% of Memory. Also try to use Morph groups,
e.g. use the Velocity Morph, instead of the Keyboard module if the Keyboard module is only used for its
Velocity output.
The internal
DSP
memory is also used by each ‘module group’, e.g. when you place the first LFO in a
patch you will see that it uses a rather large amount of memory, but the next LFO module will only use
a little memory. The reason is that some modules in a specific module group need to ‘talk to each other’
between voices, e.g. take a look at the Poly/Mono button on the LFO’s. To be able to use this function
the voices need to share some internal
DSP
memory to share one global LFO between the voices when
in Mono mode.
The
RAM
memory is used for audio delay-line effects, the reverb module and assorted effects and
modules that need memory to dynamically hold a larger amount of sound. If the first voice uses 25% of
this
RAM
memory in the Voice Area the second voice has to use another 25%, as else the memorized
audio in the two voices would get in conflict when stored in the same physical memory area (the two
voices probably use different audio signals). To make the explanation of the memory display even more
complex, the display shows either the internal
DSP
-chip memory or the
RAM
memory, depending on
which one is the biggest value. This means that it is uncertain which memory is actually shown. But in
practice this doesn’t matter as it is only the biggest percentage that will set the limit on polyphony. So,
what works very simple in practice is just very difficult to explain how it technically works.
You don’t need to understand all this technical babble to work with the G2 system, the internal G2 uses
an intelligent optimizing algorithm to find the most efficient way to use the
DSP
and memory resources.
But what you do need to understand when creating new patches is that it is the ‘magic numbers’ like 20%,
25%, 33% and 50% that are very important in defining the polyphony and it is always the biggest number
in the displays that counts. Remember that when it is about polyphony, the G2 system simply works very
different to other ‘fixed patch’ synthesizers that have a fixed polyphony. On the G2 the polyphony
depends purely on the complexity of the sound as the
DSP
programming code is different for each Patch.
On a fixed patch system the
DSP
programming code would be the same for every sound, so it will have
a predictable amount of polyphony that simply never changes. But not so on the G2 system, as it gets
totally reprogrammed every time a patch is loaded in a Slot or a new patch is created. This actually works
to your advantage in two ways; very simple patches will give relatively more polyphony than other
systems, but the G2 also allows for very big and complex patches that simply can not be done on other
synths, but with a relatively low polyphony.
CALCULATION ORDER FOR THE MODULES
As mentioned in the previous paragraphs the DSP-chips can do only one calculation at a time. This
means that the modules are processed in serial order, one after another. In cases this order can be an
issue, e.g. when there are two parallel module chains where these chains share the same source signal and
are mixed together at their ends, a one sample delay (latency) in one of the chains could affect the sound.
The G2 uses an intelligent ‘back-tracing’ algorithm to define the order in which modules are calculated.
This algorithm first identifies signal sources, like the outputs of oscillators. Starting at these sources it
traces the cabling connections and uses this information to set the calculation order for the modules. This
guarantees that there are no latency problems in parallel chains of modules. When multiple feedback
connections are made it might become obscure how the processing chain can be traced, e.g. which
feedback connection chain should be calculated first. In this case the order in which the modules are
placed on the screen is taken into account, first from top to bottom and then from left to right, and the
screen order will determine which feedback chain is calculated first.
