the SSP is an open linux platform, which you can log into, and install other software on. You can find information here in the forum on how to do that. We cannot provide any support with linux itself, but if you are a normal linux user you should be able to figure it out. The SSP uses a debian stretch rootfs. All the audio/CV I/O is usable via ALSA audio drivers. So you could install pure data, or supercollider, or other software on the SSP.
You can also find info here in the forum on how to build VST plugins for the SSP. We have an open-source VST example up on github, which you can use as a starting point. It’s a quad-VCA plugin.
From what I understand Camomille is a VST plugin which can load PD patches. So if you are a capable programmer you should be able to make it load on the SSP using the VST module. Obviously there will be some programming involved to integrate / merge the VST example for the SSP with camomille.
Hope this helps.
