[PD] PluggoPd using Jack? (was [ot?] pd and ableton via jack)

[Kyle Klipowicz]

I'm on 10.4.9 and have finally gotten a decent result for sending and
recieving audio through Jack between Live and Pd. There is an
excellent tutorial on this:
www.zenpho.co.uk/how-to-use-jack-pd-and-live.pdf.

I found that using the Audio Unit version of the Jack Insert is much
more stable than the VST one.

But, this kind of routing is a bit time-consuming, especially when
also synching up with Midi Patchbay as well. I'm hoping that the
upcoming Summer of Code will spearhead a PluggoPd that does this in a
much more streamlined fashion.

I just had an idea this week that a good route (for OSX only, sorry)
would be to look under the hood of the Jack Audio Unit (and VST too)
and the JackPilot for tips. Maybe an ambitious rewrite of the
JackPilot which uses Pd for routing could be created (there is talk
about how the Jack routing tables are a bit confusing, and Pd might be
the perfect language to express them).

If Pd could do routing in Jack, then maybe we could have a piece of
the PluggoPd puzzle?
