Basic question regarding using slider in SynthVoice

Hi everyone, this is my first post on the forum. I’ve been working my way through JUCE tutorials the past month and now find myself trying to create a basic FM synth. To get right into the crux of my problem, I have defined a slider in my MainComponent which I am trying to access in a SynthVoice class (similar to the AudioSynthesiserDemo in the examples folder). However, when I try to access the slider I get the error that its an invalid use of non-static data member. I have tried to use static and const in order to resolve the error but to no avail. Does anyone have any suggestions on how I may be able to get around this issue or what the root cause is? Thanks for your time.

It means you’re trying to call a class method incorrectly – probably a syntax or code issue.


So the specific line of code is as follows:

cyclesPerSecond = MainContentComponent::mFrequencySlider.getValue();

Not sure if that might help provide more context

Try removing the classname, it should read:

cyclesPerSecond = mFrequencySlider.getValue();


When I remove the class name it can’t find the slider

You’ll need to know and understand C++ and classes and inheritance to use the JUCE library:
