Schmidt Schmidt trigger

Schmidt.ar(in, lo, hi)

Schmidt.kr(in, lo, hi)

When in crosses to greater than hi, output 1.0, then when signal crosses lower than lo output 0.0. Uses the formula if(out == 1, { if(in < lo, { out = 0.0 }) }, { if(in > hi, { out = 1.0 }) }). Output is initially zero.

in - signal to be tested

lo - low threshold

hi - high threshold
