Translating assistance needed. Code integration for more PWM pins

So I have stumbled onto a fork of the original SoftPWM library. GitHub - per1234/PalatisSoftPWM: Software PWM library for Arduino But unfortunately as I've mentioned before I tend to have a hard time translating examples into something I understand and can implement. Using this snippet from my code:

case rSTATE1:
      {
        //initialize things
        cycle = 0;

        analogWrite(led2, random(randomLowLevel, randomHighLevel));
        random2Interval = random(randomLowInterval,randomHighInterval);
        led2Millis = currentMillis;

I know what it does because it was written by @Larryd, and then added to by me.

But I've run out of PWM pins and I am aware of the TLC5940 but I don't want to add more electronics beyond what I have. Anyways from that fork, I have an example in the library which I understand what it does. It blinks an LED but I don't know how to translate this syntax to the snippet to make the LED randomly blink/

 #include <PalatisSoftPWM.h>

SOFTPWM_DEFINE_PIN13_CHANNEL(0);  //Configure Arduino pin 13 as PWM channel 0
SOFTPWM_DEFINE_OBJECT(1);

const unsigned int fadeDuration = 1000;  // (ms)The length of time for to go from PWM value 0 to the highest level and back to 0 again. The maximum allowed value is 8388.

void setup() {
  PalatisSoftPWM.begin(60);  // begin with 60 Hz PWM frequency
}

void loop() {
  // fade from PWM value 0 to the highest value
  for (byte value = 0; value < PalatisSoftPWM.PWMlevels() - 1; value++) {
    delayMicroseconds(fadeDuration * 1000UL / PalatisSoftPWM.PWMlevels() / 2);
    PalatisSoftPWM.set(0, value);
  }
  // fade back to PWM value 0
  for (int value = PalatisSoftPWM.PWMlevels() - 1; value >= 0; value--) {
    delayMicroseconds(fadeDuration * 1000UL / PalatisSoftPWM.PWMlevels() / 2);
    PalatisSoftPWM.set(0, value);
  }
}

So in conclusion, how do I translate this library syntax to blink say...led 5 at pin13? Not necessarily asking for the code (although it would be generous) but can someone walk my through how to change it so I can learn it? Please keep in mind I do have a comprehension problem.

It look like in place of:

  analogWrite(pinNumber, value);

Where 'value' is an integer from 0 to 255.

You would put:

    PalatisSoftPWM.set(channelNumber, value);

where 'value' is an integer from 0 to PalatisSoftPWM.PWMlevels() - 1

It looks like you have to set up a 'channel' for each output pin you want to control. I hope some of the other examples with the library can help you with that because Pin 13 is the only one this example shows.

I'll see what happens when I try that down the road. I only have one Arduino ATM and my breadboards are full with my entire circuit using a uln2803 and a df mini player.

Thank you
