Lesson 2: set(), triggers and meter_()

In this lesson we will learn about more basic functions. Copy again the init app code and be ready to modify it. First we need to declare some modules we will use:

    // pdsp modules
    pdsp::PRNoiseGen noise;
    pdsp::MultiLadder4 filter;
    pdsp::Amp amp;
    pdsp::TriggerControl gate;
    pdsp::ADSR ampEnv;
    pdsp::AHR modEnv;
    pdsp::PitchToFreq p2f;
    pdsp::Processor engine;
