But for now, if you want to make a Pd wrapper VST plugin, you can just put
locks around all
pd calls. I think this first step is a good one. I'm not convinced it's
necessary to
do the next step, but let's see how this works first. At least it's nice to
be able to send
and receive pd messages between instances easily. If you really want to run
things in parallel, you can always just run Pd in a new process, which is
much safer too.
