[PD-dev] Request: Transmit control data on signal connections (including multichannel)

[Alexandre Torres Porres]

well, this didn't get much attention here, so I opened an issue on github
and maybe we can eventually discuss it over there, see
https://github.com/pure-data/pure-data/issues/1887

cheers
