Each DSP code iteration is a mod and tested using a dedicated virtual machine. They are organized in rigs and tested against other devices MAC-tables. Each Compositor mod sustain a relatively big uptime before it is applied in real-time processors. That is why each dump is successful.

Compositor NRTOS is an embedded system, which has different levels of execution. The highest level is GenEXPR DSP code and the lowest is Max scheduler. By combining two worlds, I attain to an ideal cabinet for virtual machines testing and evaluation.

Compositor uses telnet to communicate with other work groups on development of NRTOS. The development of virtual machine mods is finished and now is the stage of comparing against other devices in a form of MAC-tables. That is why the telnet functionality is constantly updated and new language patterns evolve.

Each Compositor DSP is based on a FM microarchitecture, which have evolved over time in a complete microkernel. That is why I consider MaxMSP replica NRTOS on its own. In fact, Compositor NRTOS has 8 learnable microkernels, which correspond to different versions of GenEXPR code.
