Inserting param E receiver into gen seems to result in a steady stream of Napier’s constant.
Kinda makes sense, but doesn’t 
I guess this is a MaxMSP problem and should be reported there.
Just to let you know.
Yes this is a known problem! We’ve changed it to Exp for parameter E.
If it still says E anywhere in our documentation or videos let us know so we can fix it!
Okay, most importantly i guess it’s tutorial #1, which mentions param E in all it’s images and the video.
I only briefly looked into later ones.
Hope that helps
