As part of the Vult project I have developed a new standalone library: Pla (https://modlfo.github.io/pla/). Pla is a templating library that is used in Vult to generate code in a simpler way. Thanks to this library I have developed two templates to simplify using Vult:
The template for Pure Data is more stable. It supports both, floating-point and fixed-point arithmetics. In addition, the number of inputs and outputs of the ‘external’ matches the inputs and outputs of the process function.
You can find an example of using it in this repository: https://github.com/modlfo/pd-vult-example
Exporting of objects for the Teensy Audio Library is only available in fixed-point and (currently) only supports synthesis objects (I have plans to make it as flexible as the PD template).
