is there any error message on max console?

There are no errors displaying. I am meant o interact with the patch via clicks and double clicks. They don't result in any errors, they simply don't work. This is the patch I'm trying out: https://github.com/lindseymysse/pingseqmax

Without any error message this is pure guesswork... There is one thing you could try: copy the *.class files from the code folder to the patchers folder, maybe that helps.
