Hi Susanne,

this is the description for this method from the ctcsound.py file:

 def scoreEvent(self, absp2mode, opcod, pFields):
        """Sends a score event.
        
        The event has type *opcod* (e.g. 'i' for a note event).
        *pFields* is tuple, a list, or an ndarray of MYFLTs with all the pfields
        for this event, starting with the p1 value specified in *pFields[0]*.
        If *absp2mode* is non-zero, the start time of the event is measured
        from the beginning of performance, instead of the default of relative
        to the current time.
        """

So we would need for instance:

cs.scoreEvent(time, “i”, [1, 0, 5])

Hi Victor.
Thanks for the suggestion. However, when I try it, I get a syntax error saying that four arguments were given, when 3 positional arguments were expected.

Kind regards,
Susanne

Ok, maybe the version I have has actually changed. I tried

>>> help(ctcsound.Csound.scoreEvent)

Help on function scoreEvent in module ctcsound:

scoreEvent(self, type_, pFields)
    Sends a new score event.
         | *type_* is the score event type ('a', 'i', 'q', 'f', or 'e').
    | *pFields* is a tuple, a list, or an ndarray of MYFLTs with all the
      pfields for this event, starting with the p1 value specified in
      pFields[0].

So you are right, it does not have the time argument. The version I was looking at is different.

I looked at your original code and the problem is that you are running Csound in the same
thread as you are trying to put events in. You need to run in a separate thread, see
the example

https://github.com/csound/csoundAPI_examples/blob/master/python/py3/example4.py


For instance,

>>> import ctcsound
>>> cs = ctcsound.Csound()
>>> cs.setOption('-odac')
0
>>> cs.compileOrc('''
... instr 1
... out oscili(p4,p5)
... endin''')
0

Hi Victor.
Wow, that works! I've been trying to figure this out for about a week now, so right now, I'm ecstatic. Thank you so much!

Kind regards,
Susanne
