Depending on the structure of your patches, one simple solution could be to simply stop and restart the subprocess when the parent samplerate changes.

Hello,

I have to synchronize the  samplerate inside a camomille VST plugin that uses a pd~ subprocess, with the samplerate used by the host.

I'm aware that we can specify samplerate of subprocess pd~ on creation  with the flag -sr  <samplerate> as [pd~] argument.

But is there a way to dynamically change this ?

(other than by sending a message such as

[;pd  audio-dialog 2 0 0 0 2 0 0 0 2 0 0 0 2 0 0 0 96000 30 -1 64(

to the subprocess, where only the samplerate value --here 96000-- is relevant ?)

thanks
