I added another info that I saw on Max's help file about the maximum delay. When not specified, it is set to 10 ms.Although I included this information, I'm not sure if that's how it works in Pd, so this needed to be checked and corrected if not.Another thing is that I found that the list message with arguments in Max does set ALL the arguments (max delay, D, a, b, c). But in Pd it's actually only (D, a, b, c), so we're missing a way to change the maximum buffer size, which is limiting and also a bug.Attached is the new help file with this information and considering the argument list message is how it should be (max delay, D, a, b, c).cheers2016-02-13 17:12 GMT-02:00 Alexandre Torres Porres <porres@gmail.com>:I found problems in the help file of [comb~] so I made a new version correcting it and giving more information, find it attachedcheers
