[LAU] oscilloscope like wave display for jack?

Happily I just realized, that after ~six years xoscope has it's new version announced a couple of hours ago, though not yet downloadable. But it now offers alsa support. That makes me wonder, wether there is a (lv2) plugin or jackified programm, that is capable of live displaying of audiowaves in an oscilloscope like fashion, even overlay two channels? I would not mind if it is limited to audio use/range at all. The Calf plugin suite has a nice analyzer, but it lacks this oscilloscope like display of waveforms. And since I only need it for audio, I would rather not buy a real one Sure, I now could always dedicate the onboard soundcard to xoscope, but maybe there is a more integrative way with the convenience of jack routing. And I might want to use onboard sound for smpte one day as well.
