Inside a built-in module

1Open it

1. In the Patch, double-click a module, or choose View code in its menu (⋯ on its card).
2. Its code takes the Patch's place, with the way back in the breadcrumb above it.
3. Its card stays beside it: turn its knobs and play while you read.

2Read it

The bar over the code says Built-in · read only. The code is exactly what runs, the comments at its top say what it does, and every line is the same kind of line as in a Code module: y' is y one sample ago, and rate the samples in a second.

Some names in the code aren't the card's: in is a word of the code, so the Filter's in is x there. The bar lists them.

3Its graph

Choose Graph or Both to see the same code as a picture of its maths, as a Code module's: every +, × and function a box, its wires, and each y' a one-sample delay with its loop drawn back. Choose a box and its part of the code lights up; the cursor in the code chooses its box.

Its knobs show their values now, as on its card: turn the cutoff and the graph's cutoff follows.

4Not written in code yet

Some modules are still written in C++, the language SynthMaker's engine is written in. They open too, and say so: Written in C++ for now; its code arrives in a later update. SynthMaker never shows code that isn't what runs.

5Edit a copy

A built-in never changes. To change one, choose Edit a copy in the bar over its code. In this sound only, the module becomes a Code module of your own, Filter (mine), with the same code under a name of its own, MyFilter. It keeps its wires and its knobs where they were, and it sounds exactly the same until you change a line.

You stay inside it, and now its code is yours to type in. Undo brings the built-in back.
