Description

The CQVamp plugin has fixed-sample-rate dense 3d model output in which each output vector has a timestamp.

SV has a bit of trouble with it, for a few reasons. To start with, the features began at a time earlier than zero, which crashed SV completely. Having chopped off the pre-zero features, SV is displaying the results but introducing gaps into the display of the output occasionally (rounding error?). And occasionally it will crash late on in processing, with a seg fault at
