4.3 DSP Resource Management
Due to the Duende PCIe having multiple DSP chips, a
minimal amount of resource management should be done
when running Duende PCIe at high load.
If there are, for example 2 slots free and you wish to load a
stereo plug-in, Duende PCIe will under certain conditions
notify you that you are out of DSP resources. This will only
happen if the two slots are on different DSP chips as Duende
PCIe is not able to load a stereo plug-in across 2 chips. This
may well occur because you have filled up all the resources
and subsequently unloaded 2 mono plug-ins. This situation
can be seen in the diagram below.
As you can see above, the two remaining slots reside on
different DSP chips and in this case when you attempt to load
a stereo plug-in you will encounter the above mentioned
situation.
The way to handle this is as follows:
1. Save your project/song
2. Close your project/song
3. Re-open project/song
When this has been done Duende PCIe will be forced to reload
all the plug-ins but will do so in the most economical way
possible. The 2 free slots will now reside on the same DSP
chip allowing the loading of a stereo plug-in.
