NMG2 Open source editor

With the NMG2 Open source editor you can make patches on the Clavia Nord Modular G2 synthesizer using the USB interface or using midi. It is an alternative to the original Clavia editor software. The orignal Clavia software still works o.k. on the latest o.s. for PC and Mac, so you don't really need the open source editor. But since the Modular G2 synthesizer is discontinued by Clavia, there may come a day that the editor doesn't work anymore on a future new o.s. The goal of this project is to have an alternative in place when that day comes, and in the mean time add some functionality the original editor doesn;t have, like a G2 Vst.

AutoREALM

AutoREALM is a free role-playing game mapping program originally made by Andrew Gryc. This program is an excellent mapping program that can design castles, caves, cities, dungeons and more. New developers are more than welcome! Previously, development were using Delphi language. Some attempts to rewrite it in other languages were done, but currently (since January 2012) there is an attempt or rewrite using those technologies: _ C++11 _ wxWidgets 2.9 (will be 3.0 when it will be released) _ openGL _ pluma framework (a fixed version located on bitbucket) The design of the actual C++ code-base primarily targets clean source code and high modularity of source code, to allow easy reuse of the code and fast learning for people who might join the effort. Current development is located on https://bitbucket.org/bmorel/autorealm . Howerver, older repositories are still here in case someone would like to consult them, and to allow easy access to algorithms they might contain.

Tron

Tron is a console application (now discontinued) which simulates user intervention for otherwise unscriptable applications. It can simulate keystrokes, mouse clicks and movements from scripts allowing the control of applications running in the foreground. It can be used to write automated tests for user interfaces or to ease repetitive jobs with applications which do not support scripting natively. It has a modular design which allows it to be extended easily and is not tied to any particular scripting or programming language.
