Hi I have an app which generates a signal through the output of a USB-4431. This is looped back to an input and captured. The capture and playback is synched via a start trigger (/ai/StartTrigger). This produces a perfectly reproducible waveform capture (i.e. sample accurate). The capture buffer size is 100 kS, the generator buffer size is 50 kS. The sample rate is 48 kHz Unfortunately every once in a while I get an error that looks this: and at other times I get this: Reducing the sampling rate to 1 kS resolves everything and it chugs along nicely. I would really like this to work at higher sampling rates. What are my options? Thanks Nirvtek

Regeneration worked fine. Playing back the source sample once and letting it repeat by itself resolves the issue.

Unfortunately I sometimes need the waveform to change halfway thorugh. Will post here if I figure out how to make it work.
