For creating a Machine Learning environment in connection to Max, I'm using the stand-alone software Wekinator, developed by Goldsmith's teacher Dr. Rebecca Fiebrink, one of the currently main go-to names in computer music and Machine Learning.
Although the first edition of the software is dated back to 2009 and it's black-box functioning system regarding the ML process might lead to more restricted results compared to a full developing of a music-ML connected system in languages like python and C++, the choice to apply the program comes as a pragmatic choice that already leads to the intended results for the project. For the same reason, it is also an interesting possibility in regard of another softwares that also lead to a bigger democratization on the use of ML for the use of the artistic community in general (like the recently released Runway).
