kijjaz's clipper 01: a class for doing the linear digital clipping, built only from Step, Gain, HalfRect. Connect the desired signal to .input and chuck out from .output to have the calculated result.

class kjzClipper01 // clip signal within -1 to 1 with simple UGens
{
   Gain input; // chuck input signal to this
   Gain output; // chuck this out to have the result
   
   Step one; 1 => one.next;
   input => HalfRect a;
   one => a; // calculate a from HalfRect(input + 1)
   one => Gain two; 2 => two.gain;
   -1 => a.gain;
   a => HalfRect b;
   two => b; // calculate b from HalfRect(2 - HalfRect(input + 1))
   -1 => b.gain;
   one => output;
   b => output; // the result we want: 1 - HalfRect(2 - HalfRect(input + 1))
}
