I'm not sure how cs.resetSession(csdfile) works. The description says:

"Reset the current session, eventually loading a new csd file"

Does that replace the existing csd file or add the new csd file to the 
thread?

I am trying to convert Steven's OSCsound example to make use of 
ctcsound, not csnd6.

BTW, in order to use resetSession without errors I had to use this:

     cs = 
CsoundSession("/Users/richard/PycharmProjects/OscCtcSound/csds/Mono_Synth.csd")
     time.sleep(10)
     cs.stopPerformance()
     cs.reset()
cs.resetSession("/Users/richard/PycharmProjects/OscCtcSound/csds/vco2test.csd")

But as I said I am not sure at this point of both csd's are loaded...

Yes, but what if I need to add new instruments? In ctcsound I found the following code that I think I need:

    def compileCsd(self, csd_filename):
        """Compile a Csound input file (.csd file).
       
        The input file includes command-line arguments, but does not
        perform the file. Return a non-zero error code on failure.
        In this (host-driven) mode, the sequence of calls should be
        as follows:
       
            cs.compileCsd(args)
            while (cs.performBuffer() == 0)
                pass
            cs.cleanup()
            cs.reset()
       
        NB: this function can be called during performance to
        replace or add new instruments and events.
        On a first call and if called before start(), this function
        behaves similarly to compile_().
        """

But this is not called in csoundSession()...

cs.resetSession resets the current session, eventually loading a new csd file. This means that if no csd filename is given as parameter or if the same csd filename as the actual one is given, the system just resets the csd. If a new csd filename is given as parameter, then the system is reset with this new csd which replaces the old one.

I hadn’t come across it before, that’s a very interesting one.

Of course. BTW, there should be more info on how to use this, maybe in a Csound Journal article?
For instance, the first csd loaded with CsoundSession() is a normal csd file with header containing <CsOptions>,  sr, kr, etc, and a generic orc section.
The next csd, loaded with compileCsd() cannot contain <CsOptions> and a section with sr, kr, etc. (Csound complains about global variables already set)
It can contain a global orc section, however.

Richard

CsoundSession is a subclass of ctcsound.Csound and so it has de facto all the methods of ctcsound, particularly compileCsd, compileOrc, and compileOrcAsync which can be used to add instr on the fly.
