Earlier this year, I offered obo which was a Max version of the popular tonematrix tool. I've adapted obo for use in maxforlive, added monome 128/256 support (not required for operation), 16 pattern memory, edit while play, copy/paste patterns and a scale generator (whew). Here is a video.
As this video involves screen capture, I recommend viewing the video in full resolution at the video's youtube page (vimeo only allows one HD upload per week for plebeian customers, booo), and enable HD. Otherwise, you won't be able to see what is going on inside the user interface.
