Schmidt : InRange : UGen : AbstractFunction : Object

Schmidt trigger.
Source: Trig.sc

Description

If in > hi, output 1. If in < lo, output 0. Otherwise, repeat the last sample of output, assumed to be 0 at initialization. In sclang-flavored pseudocode:

out[i] = if(in[i] < lo[i]) {
    0
} {
    if(in[i] > hi[i]) {
        1
    } {
        out[i-1]
    }
};

Examples

s.boot;

{ Schmidt.kr(SinOsc.kr(1, 0, 0.2), -0.15, 0.15)}.scope; // see the trigger

{ Schmidt.kr(MouseX.kr(0, 1), 0.2, 0.8)}.scope; // try it with the cursor

// threshold octave jumps
(
{
    var in = LFNoise1.kr(3);
    var octave = Schmidt.kr(in, -0.15, 0.15) + 1;
    SinOsc.ar(in * 200 + 500 * octave, 0, 0.1)
}.scope;
