Hello! Somehow I have closed the Display Window in CsoundQT (the one that shows waveforms when playing a sound) even when I run a program which uses the display opcode it does not show up.

I’ve experimented with the “view” drop down to no avail. Any tips?

Thanks!

There is no window showing waveforms. There is a widgets window. To use the “display” opcode (or the “dispfft” opcode), create a “graph” widget. For an example see Examples/CsoundQt/Widgets/GraphWidget. Make sure the widgets window is open (see View/Widgets)

Thanks! I looked into that and was able to make some progress.
