Maybe add audio/control rate boiler code?

Hi again.

Just a heads up / FYI. I am using this to write my first ugens (hurraaay!!) and it's going fairly well, but as a newbie to this I just wanted to let you know that I found the lack of audio/control rate distinction a bit confusing.

If you build and run the example plugin that this template generates, it emits horrible noise if you just set the gain to a fixed value like 0.5 but fine if modulating by audiorate SinOsc.ar(0.1) for example. This to me (as a newbie) was a bit confusing.

I know this would be at the cost of making the default example here more complicated but I would personally have preferred if the audio/control rate stuff was a bit more verbose in the built example :)

// 1. set the calculation function.
  if (isAudioRateIn(1)) {
    // if the gain argument is audio rate
    set_calc_function<SimpleGain, &SimpleGain::next_a>();
  } else {
    // if thene gain argument is control rate (or a scalar).
    set_calc_function<SimpleGain, &SimpleGain::next_k>();
  };

  // Check if "gain" is control rate or audio rate
  if (isAudioRateIn(1)) {
    next_a(1);
  } else {
    next_k(1);
  }

etc

And thanks again for this awesome tool !

best!

ah no sorry, maybe it's better to just update the next function to use in0 instead for the gain arg?

void SimpleGain::next(int nSamples) {
  const float *input = in(0);
  const float gain = in0(1);
  float *outbuf = out(0);

  // simple gain function
  for (int i = 0; i < nSamples; ++i) {
    outbuf[i] = input[i] * gain;
  }
}

i'd be happy to accept a pull request, but i currently have no time to spend on this repo, sorry. i agree this would be a good addition

Cool I can cook up a PR. Thanks!
