Examples

// compare:

(

{

    var mod = SinOsc.kr(Line.kr(1, 10, 10));

    SinOsc.ar(mod * 400 + 500) * 0.1

}.play;

)

​

(

{

    var mod = SinOsc.kr(Line.kr(1, 10, 10));

    SinOsc.ar(LinExp.kr(mod, -1,1, 100, 900)) * 0.1

}.play;

)

​

// modulating destination values.

(

{

    var mod = LFNoise2.ar(80);

    SinOsc.ar(LinExp.ar(mod, -1,1, MouseX.kr(200, 8000, 1), MouseY.kr(200, 8000, 1))) * 0.1

}.play;

)

linexp and exprange can be used to create a LinExp implicitly from a ugen, mapping its output values from linear range to an exponential one. The rate is derived from the ugen.// linexp ( { var mod = LFNoise2.ar(80); SinOsc.ar(mod.linexp(-1,1, MouseX.kr(200, 8000, 1), MouseY.kr(200, 8000, 1))) * 0.1 }.play; ) // exprange ( { var mod = LFNoise2.ar(80).exprange(MouseX.kr(200, 8000, 1), MouseY.kr(200, 8000, 1)); SinOsc.ar(mod) * 0.1 }.play; )
