Okay, so it’s another free graphical audio and interactive development environment, with a patching interface (again), and synthesis, MIDI, and real-time processing features (again). But Open Sound World deserves at least a brief look: it has some programmer-friendly features, it’s easy to add features (including via C++), and runs on every platform (Mac/Windows/Linux, even SGI). And, of course, it’s free and open source, which is good. See the online documentation for more details; could be just right for your next project. I’ll stick with Pure Data (Pd) myself. Thanks, Adrian!
