supercoil is a live codable modular synth in a single HTML file, inspired by SuperCollider.

You can use it here: https://felixroos.github.io/supercoil/

The HTML file is doughbeat with a minimal version of kabelsalat up front. You can look at the source code within doughbeat here ( might be out of date, but you get the idea )

Here's an example of an audio graph:

saw(55).lpf(sine(2).range(0.2, 0.8), 0.2).out();

In this example, we have a sawtooth wave at 55Hz going into a filter that is modulated with a sine wave. You can chain any of the below functions. Make sure to end with .out().

• saw(freq) sawtooth oscillator
• sine(freq) sine oscillator
• pulse(freq, duty) pulse oscillator
• range(input, min, max) scales bipolar signal to range
• delay(input, time) delay signal by time
• ad
• add(a, b) add
• adsr(input, a,d,s,r) ADSR envelope

• apply
• ar
• audioin
