Select abstractions are a variety of small patchers that perform useful functions with varying outputs.
b.blocks is a library for Max/MSP/Jitter, providing a set of modules for quick prototyping in interactive multimedia systems. Existing modules include video analysis, audio and communication with external devices. Each module is an abstraction, used inside bpatcher objects, providing a set of controls for each module's main functions.
A few useful abstractions I've created to help me out in my everyday patching.
Authors: Daniele Ghisi and Andrea Agostini bach: automated composer's helper is a cross-platform set of patches and externals for Max, aimed to bring the richness of computer-aided composition into the real-time world. bach provides you with two new data types: rational numbers and lllls (an acronym for Lisp-like linked lists), the latter being a list capable to contain other lllls in itself, a bit like a Lisp list.
Small update: A couple of abstractions have been added and some existing ones have been cleaned up a bit. This is a growing set of abstractions dealing with simple drawing issues.
