Hi Camilo

for me the former (a graph with boxes and arrows) is definitely much
better solution. The graph makes the structure pretty clear. With the
patchbay-style I feel quite lost how the overall data flow would look
like.

Anyway the implementation using a graph should not require a lot of
work - there is Qt graphics view framework that greatly simplifies the
whole task.
