Jamoma provides a clear structure and common features for building max patches. reducing the amount of time needed to create new performance systems, and enhancing the interchange of patches amongst max users.

A set of 50 abstractions for performing both common and awkward tasks in Max/MSP. Categories include control, data, list processing, numbers, pattr-family, statistics, strings, and user-interface. Most perform multiple related functions and are unbiased as to data type where possible. Additionally, the download contains help files.

This set of objects is capable of generating an infinite amount of attractors by automatically constructing nonlinear equations. These formulas are of the type quadratic and cubic, so their highest term is to the power of two (quadratic) or three (cubic). The quadratic equations go up to four dimensions, the cubic up to three.
Example patches are included.

The Jimmies is an historical collection of patches, abstractions and external objects developed for the MAX/FTS environment on the ISPW at the beginning of the 1990s, and assembled into a formal collection of tools by Zack Settel in 1993.

Zack Settel developped a new free version of the Jimmies called xjimmies : http://www.maxobjects.com/?v=libraries&id_library=100

Jitter is a set of 135 brilliant new video, matrix, and 3D graphics objects for the Max graphical programming environment. The Jitter objects extend the functionality of Max4/MSP2 with flexible means to generate and manipulate matrix data -- any data that can be expressed in rows and columns, such as video and still images, 3D geometry, as well as text, spreadsheet data, particle systems, voxels, or audio. Jitter is useful to anyone interested in real-time video processing, custom effects, 2D/3D graphics, audio/visual interaction, data visualization, and analysis
