adjph Posted March 30, 2015 Share Posted March 30, 2015 Mac pro late 2013 3.5 GHz 6-Core Intel Xeon E5 in Yosemite 10.10.1, LPX 10.1.1 I tried recording 2 violin tracks at 96K 24bit, to find playback intermittently stuttery from a Thunderbolt drive.The audio appears to have written to disk correctly. I also tried palying back the audio from an SSD drive. Same problem. Anyone else finding this? My guess is it's a Yosemite issue - I found other posts about Energy Saver preferences, but they were for previous versions of the OS Quote Link to comment Share on other sites More sharing options...
shivermetimbers Posted March 30, 2015 Share Posted March 30, 2015 What is your I/O buffer setting during recording? At playback? Quote Link to comment Share on other sites More sharing options...
adjph Posted March 30, 2015 Author Share Posted March 30, 2015 256 samples for both. Should have mentioned 64gb RAM. Quote Link to comment Share on other sites More sharing options...
shivermetimbers Posted March 30, 2015 Share Posted March 30, 2015 Try 1024 on playback. Are you using any inserts (Compressor, reverb, etc) ? Quote Link to comment Share on other sites More sharing options...
adjph Posted March 30, 2015 Author Share Posted March 30, 2015 Ok thanks. No track inserts used on that session which was only a test. I work a lot as a film composer with small (4 or 5 musicians) ensembles, and it's simply not viable to work in this way in the pro world.

senseinj Posted March 31, 2015 Share Posted March 31, 2015 adjph, were you able to solve the issue? Quote Link to comment Share on other sites More sharing options...
adjph Posted March 31, 2015 Author Share Posted March 31, 2015 No. I'm going to try some more tests today, and AB it with Pro Tools 11 - I'll post results later. Quote Link to comment Share on other sites More sharing options...
adjph Posted March 31, 2015 Author Share Posted March 31, 2015 OK - thanks to shivermetimbers, 1024 buffer on playback seems to work fine, but obviously can't monitor with that - so I won't monitor through the DAW which isn't ideal. Quote Link to comment Share on other sites More sharing options...
