After my search for a realtime waveform viewer a while ago didn't quite yield the result I was looking for, I decided to write one myself. So here's the first release of jack_oscrolloscope (thanks Dave Robillard for inventing the name): http://das.nasophon.de/jack_oscrolloscope/ I hope someone finds this useful. Feedback is appreciated, please let me know if you encounter any problems. Cheers, Dominic
