Would it be possible to add the HID object to plugdata?

yes and no

• No because plugdata doesn't have externals of its own and tries hard not to add other libraries, specially abandoned ones (not sure exactly what is the state of hid, I'll guess it's abandoned)
• Yes because I can add it to "ELSE"
• No because I will not simply use 'hid' as it is and include it in ELSE.
• Yes because I can create a new object with the same functionality and include in ELSE

The thing is that this is not a big priority for me right now, but if there's enough request and people would like to contribute with me, I say let's do it :)

Thanks for your response! That definitely makes sense.

IMO it's worth a certain degree of special consideration because it adds a fairly substantial class of new functionality to puredata (ie receiving control data from a wide array of peripheral devices which otherwise would not be able to send any musically useful information)

I also understand that while cool, it might not actually be something that a lot of people would use.
Judging by the fact no one has requested it yet this is probably the case.
But perhaps the original object just isn't something many people know exists.

I would certainly contribute by way of bug reporting and testing but I'm afraid thats where my abilities end.
