I have Max 5.1.5 on an Apple Mac Pro with OS 10.6.4. I am trying to use a patch called MoP-TOols-264 that I used frequently during the 2007-2008 school year. I primarily used the patch in an electronic music studio at school, but did use it with success on my Powerbook with a demo of Max 4.?? during the summer of 2008. My Powerbook has since died and been resurrected, but MoP-TOols-264 will not work on the Powerbook with a downloaded Max 4 demo. I have read various articles about using earlier patches in Max5, and have correctly identified the file paths for the MoP-TOols-264 patch and subpatches. Error messages upon opening subpatches include "unknown external object type," "no such object" and "doesn’t understand ." These errors occur with many different objects and commands. I have tried to find an updated version MoP-TOols-264 (or any mention of it on the internet for that matter) to no avail. Any insight on how to get this patch working would be greatly appreciated!
