I’m new to juce so now I’m follwing this video,
I think I did the same with this video but I’ve getting this compling errors.
‘juce::AudioParameterChoice::AudioParameterChoice(const juce::String &,const juce::String &,const juce::StringArray &,int,const juce::String &,std::function<juce::String (int,int)>,std::function<int (const juce::String &)>)’: cannot convert argument 3 from ‘_Ty’ to ‘const juce::StringArray &’
I’m not sure why I got this error.
Please show the code you’re using to construct the AudioParameterChoice. At a guess you probably did something like { "On", "Off" } for your choices parameter and you’ll solve it by putting juce::StringArray { "On", "Off" } there instead. My assumption is that the compiler can’t implicitly decide what type you’re giving, so explicitly stating it would solve the issue. Complete guesswork though without your code.
juce::AudioProcessorValueTreeState::ParameterLayout TapSynthAudioProcessor::createParams()
{
std::vector<std::unique_ptr<juce::RangedAudioParameter >> params;
// OSC
params.push_back(std::make_unique<juce::AudioParameterChoice>("OSC", "Oscillator", juce::StringArray{ "Sine" , "Saw" , "Square" }, 0));
Here is my code, thanks for replying, I use VS in window btw
EDIT: I changed like this but I haven’t resloved yet
Seems to be correct, basically the same as I have used AudioParameterChoice myself without issue before, so I’m not sure where your error is coming from. 
This is the part of my code.
juce::AudioProcessorValueTreeState::ParameterLayout TapSynthAudioProcessor::createParams()
{
std::vector<std::unique_ptr<juce::RangedAudioParameter >> params;
params.push_back(std::make_unique<juce::AudioParameterChoice>("OSC", "Oscillator", juce::StringArray{ "Sine", "Saw", "Square" }, 0));
Here I bring detailed error logs
Reason: cannot convert from ‘_Ty’ to ‘const juce::StringArray’
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
I checked the error and this code appeared. It was in the External Dependencies/memory
template <class _Ty, class… _Types, enable_if_t<!is_array_v<_Ty>, int> = 0>
_NODISCARD unique_ptr<_Ty> make_unique(_Types&&… _Args) { // make a unique_ptr
return unique_ptr<_Ty>(new _Ty(_STD forward<_Types>(_Args)…));
}
I haven’t gotten anything about why this conversion failed. Is it related with my coding setting? Do I have to install other extension packs or something?
I thought I had this error for a while, turns out I’d somehow ._. managed to switch a different line of code which was adding int parameters to use the AudioParameterChoice type, so the error was coming from this line and not where I was trying to actually add the choices.
