I dont see how the current scope sink can have more than one channel.
However, you could change the scopesink2's scope_sink_f to connect all
possible 16 inputs. Of course, this would only work with the hier2
stuff, but you would be able to use any number of inputs (1-16) without
fuss. This little trick will not work for the complex inputs. For
complex, you would have to use the scope_sink_f, and place a bunch of
complex to floats on the outside of the block.

Indeed the float allows more than 2 channels. I will take a look at
the complex scope to see what needs to be fixed. You know I am
continually amazed by this software! I was just thinking how nice it
would be to have the magnitude displayed and BAM, complex_to_mag
presented itself.
This is great stuff!

Thanks I will take a look at it.
