[PD] multi-source convolution help (with external details)

[J. Scott Hildebrand]

it's been almost a year since i've really been into the external coding,
and right now i'm trying to do something i just don't know how to do.
the first three inlets will always be there and they are select, azimuth,
and elevation. after that is the user specified amount of sources for
which there will be one mono input each. i'll paste that part of the code
here for anybody who's interested in helping me out. thanks!
