I'm hoping you all can explain a basic concept of using Python/ctcsound to control live performance of Csound. How can I track the time-based element of performance within Python? Here's an example that illustrates my question. I've got a Csound orchestra with algorithms that generate note events in real time, and I can change parameters in these algorithms live. Csound tracks performance time internally, so it knows when to trigger the note events. However, if I want to port these algorithms and interactivity over to Python/ctcsound, how can Python track the performance time? Is it possible to tell Python, "In 1.3 seconds trigger this note in Csound"? Does Python have an internal clock? Or do I have to rely on Csound itself to send time information back to Python? Sorry if this question sounds very uninformed and muddled! I'll be embarking on some Csound/Python projects in the coming weeks and need to wrap my head around it. Thanks! Jason |

You should have a look at scoreEvent, scoreEventAbsolute (https://csound.com/docs/ctcsound/ctcsound-API.html#ctcsound.Csound.scoreEvent) which are methods of the Csound class, or at the scoreEvent method of the CsoundPerformanceThread class (https://csound.com/docs/ctcsound/ctcsound-PT.html#ctcsound.CsoundPerformanceThread.scoreEvent). Definitively you should rely on the Csound performance clock. François Le mer. 23 sept. 2020 à 15:39, Jason Hallen <hallenj@gmail.com> a écrit :
