4.3 DSP Resource Management

Due to th e Du ende PCIe havi ng multiple DSP chi ps, a minimal amou nt o f resource m anagement 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 wi ll under cert ain conditi ons 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 m ono plug-ins. This situation can be seen in the diagram below.

As you can s ee ab ove, the two rem aining slot s reside on different DSP chips and in this case when you attempt to load a s tereo plug-in you will encount er the above menti oned 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 s lots will now reside on the s ame DSP chip allowing the loading of a stereo plug-in.
