Hi,
OB does a good job in latency compensation when using the built in USB-Audio-Connection. But you cant turn this off (or at least I havent found it) when you want to record the audio via a separate Audio interface. I made this running in Live with an external instrument rack with only 2 to 3 ms latency (instead of 45 ms when using the built in Audio Interface). OB is now running on another track, just for parameter control via midi. But it still reports the same latency to live as it would when capturing audio.
It would be nice to turn this off, to use OB just as a normal MIDI-Plug-in-Controller without the audio capture and latency compensation.
Cheers
