Hi - I just switched to an Apogee Symphony 64. I've been using MOTU products for years and never had any issues with latency. I would just change my Input Monitoring Mode to Direct Hardware playthrough and it worked, every time. Now, for reasons I cannot figure out, sometimes it records just swell, no latency, and other times (like now) I cannot get rid of the latency. I did a pass on my piano and it was perfect. I went to overdub a passage and now my piano is sounding way late. I've changed the buffer size, brought it all the way down to 32 - no change. When I first recorded to today it was set to 128. I have my work priority set to high and I am using word clock run by my Aardsync. I have 80Gb of memory and it's a Mac Pro (mid 2012) with 2 x 3.06 GHz 6-Core Intel Xeon processors. This should be plenty of speed and power to easily do this. This track only has a couple of live voices and some other stuff, maybe 20 tracks all told - so track count should not be a problem. Is there a simple way to fix this? What am I missing? Thanks

Did you add a limiter or other look-ahead plugin anywhere in the project? Master Buss?

No - nothing. There are no plugins and no Master track set up. I'm just beginning to record this track. And by the way, I just switched to a test track with the exact same settings, and it was perfect. So I switched back to my original track, and it is perfect as well. This just seems to happen every now and then - I cannot seem to figure out what is going on. I cannot imagine that it is DP as I know this program so well. It just seems to be the Apogee gets weird and then gets better. I didn't even shut the system down ...
