Some explanations on how Juce works

Hi there!

I’m completely new to Juce. For a project in my lab I have to build a wavetable synthesiser where from Qt I receive a signal (in this signal is the frequency I want to set) and I have to play a tone. So I used the example from the tutorials: JUCE: Tutorial: Wavetable synthesis but I can’t figure out how to actually play the tone. From what I understand, the getNextAudioBlock is the class method that put data in the AudioBuffer, but I’m unable to use it (as prepareToPlay)… Processing: Wavetable.cpp…
Processing: Wavetable.h…
