According to the first post, the OP has already tried setting the buffer to its lowest setting. Their experience with Avid coreaudio drivers is similar to a lot of other peoples, I think. Reducing the sample buffer will help minimise the latency, but it still doesn't get HDX or HDN devices anywhere near the latency they have inside Pro Tools, or other low-latency native counterparts like RME or Lynx devices.
Some food for thought. At 48kHz:
- HDX has a base latency of ~1.7ms in Pro Tools.
- HD Native with a 32 sample buffer will have a latency of ~2.5ms in Pro Tools.
When running in Logic with a 32 sample buffer using the coreaudio drivers, they both have a latency of around ~14ms. For some people that will work just fine, but for many people who purchased HDX or HDN to use for low latency monitoring, it is obviously magnitudes worse under coreaudio/ASIO than it is inside of Pro Tools. Just for comparisons sake, an RME HDSPe Madi card will have a latency of ~3ms at 32 sample buffers in both Pro Tools & Logic. To get anywhere near the ~14ms of HDX or HDN running under coreaudio, you would need to set the RME to a sample buffer of 256.
