Default values

> g_00 = cuspL AR 22050 1.0 1.9 0.0 * 0.1

Vary frequency

> g_01 =
>     let x = mouseX KR 20 (sampleRate / 2) Linear 0.1
>     in cuspL AR x 1.0 1.99 0 * 0.3

Mouse-controlled parameters.

> g_02 =
>     let x = mouseX KR 0.9 1.1 Linear 0.1
>         y = mouseY KR 1.8 2.0 Linear 0.1
>     in cuspL AR (sampleRate / 4) x y 0 * 0.3

As frequency control.

> g_03 =

>         y = mouseY KR 1.8 2.0 Linear 0.1
>         n = cuspL AR 40 x y 0 * 0.3
>     in sinOsc AR (n * 800 + 900) 0 * 0.4
