We are now going to dive into the world of Gen. By the end of this chapter, we will be able to create very efficient external-like objects that can be reused and exported to other kinds of code such as GLSL and C++. In fact, Gen patches are like regular patches, but they get converted to text-based code and compile right away to more efficient code. We could say that Gen patches are some strange objects that are somewhere between a subpatch, an abstraction, and an external written in C++. However, besides the advantages regarding performance, there is another big advantage on the audio side of Gen. We can use single sample delays that feature feedback, which is a problem in the MSP domain. Therefore, in this chapter, we will concentrate on examples that require short delays that feature feedback such as filters and physical modeling. Since this book proposes to use Max/MSP for audio and TouchDesigner for video generation, we will emphasize on the audio...
