I have the latest MaxSoundBox on my Packages folder and this folder is on the search path.
I found an other yin~external in that path Macintosh HD :/Users/omarkarray/Documents/Max 8/Packages/ircam-omax_y-Max6.1/externals/yin~.mxo so delete it and empty the trash.
Now on my max console i have this message : yin~ (pitch analysis), version 1/2021 (15)
So no i pass without the activaton modal. But Yin~ on the help file dose not seems to process.
see in the attachement the short video demonstrating the issue that i have. here i have also rooted the signal coming from sfplay~ to the dac~
Signal is present and passing to Yin~ but no signal at all in the output …
