and in fact that's the only sane way to do it. a bus cannot have a
waveform (that requires a history and stored data). there is no such
thing as a "realtime waveform". if you just want a few bars of history
to look at which then are discarded, you could attach a scrolling scope
via jack (fons did one iirc), or keep a rt spectrum analyser running
(one with history, such as baudline, which is closed source, though).
