Thanks, please do!

I don't have experience with multichannel connections, and AFAIU they
are quite new, right?

It would be great to extend the externals to support that, but they
are implemented with the flext library, which isn't really maintained
anymore, so I guess it won't get multichannel support.

One option would be to drop the flext implementation and rewrite it as
a "pure" Pd externals.
However, I don't think that I'll have the time to do that ... but if
somebody else wants to contribute it, that would be great!

cheers,
Matthias
