inspired by your comment and your shared document, I reversed engineered all the SysEx implementation in the MicroBrute and created a Python application that provides all the functionality of the Microbrute Connection but the firmware upload and sequence reset.
My primary goal was to run it on Ubuntu so I don't know how to run it on other OSs.
The application is available at https://github.com/dagargo/microdude
. It provides a user interface and a connector to be used as a Python module to get and set messages to the MicroBrute. Also, due to the lack of official information I documented the SysEx implementation inside the project.
