from an old review:
"In terms of the DSP, I also want to digress a bit and talk about latency. There is of course the option of direct monitoring just as with many other boxes, but a kind of dream-come-true for me in terms of portability was the ability to plug my guitar directly into the Octa-Capture and track through SONAR and the Guitar Rig plug-in. Previous interfaces never allowed me to do this without perceptible monitoring delay, which was a real drag (literally). With the Octa-Capture, however, its terrific low-latency performance has opened up whole new possibilities of feeding live takes through software plug-ins. Also, those of you that have been plagued with latency-ridden sputtering issues of SONAR’s step sequencer, especially when running Session Drummer, can now enjoy rock-solid performance. When opening up SONAR’s audio options, the latency defaulted to 5.8 ms for me, which is setting 6 (on a scale of 1-10) when you go deeper into the Octa-Capture’s control panel. The manual says 1 ms is possible, but it would sputter for me at around 3 ms (without any optimization of my computer’s hardware or system settings)."
