Examples

// examples:

(
{
    var mod = SinOsc.kr(Line.kr(1, 10, 10));
    SinOsc.ar(LinLin.kr(mod, -1,1, 100, 900)) * 0.1
}.play;
)

// modulating destination values.
(
{
    var mod = LFNoise2.ar(80);
    SinOsc.ar(LinLin.ar(mod, -1,1, MouseX.kr(200, 8000, 1), MouseY.kr(200, 8000, 1))) * 0.1
}.play;
)

// modulating source and destination values.
(
{
    var mod = LFNoise2.ar(80);
    SinOsc.ar(
        LinLin.ar(mod,
            SinOsc.kr(0.2), SinOsc.kr(0.2543),
            MouseX.kr(200, 8000, 1), MouseY.kr(200, 8000, 1)
        )
    ) * 0.1
}.play;
)

linlin and range can be used to create a LinLin implicitly from a ugen, mapping its output values from linear range to an exponential one. The rate is derived from the ugen.

// linlin
(
{
    var mod = LFNoise2.ar(80);
    SinOsc.ar(mod.linlin(-1,1, MouseX.kr(200, 8000, 1), MouseY.kr(200, 8000, 1))) * 0.1
}.play;
)

// range
(
{
    var mod = LFNoise2.ar(80).range(MouseX.kr(200, 8000, 1), MouseY.kr(200, 8000, 1));
    SinOsc.ar(mod) * 0.1
}.play;
)
