Hi Guys,
I got my RME Babyface Pro setup with Sonar Platinum on my Asus G752VY laptop... my glitchy recording problem seems to be gone.  With the MOTU 828x connected with Thunderbolt, the lowest round-trip latency I could get at a 256 sample buffer was about 19ms... the RME at the same buffer size is 12ms.  I can run most sessions with the RME at a 64 sample buffer size with a round-trip latency of 4ms no problems.  On big sessions with lots of plugins, I have to run at 128 sample buffer size to be on the safe side.  I still need to spend more time with it, but so far there have been none of the problems i was having with the MOTU.  The RME TotalMix FX software is way more versatile than MOTU's CueMix software as well.  Looks like I will be selling my MOTU 828x... that was a frustrating 6 months of testing things... at least i learned a fair bit ;-)

Good news Rob! Fingers crossed:)

Hi Mark,
 
The MOTU units are behaving fine recently ... stability is spot on and I actually just went back and doubled checked my mini-dumps directory to find only 3 dumps in there since moving to MOTU back in August ... I do remember all 3 of them (which means that there really were no more than that) and all were caused by "ignorant user practise" (1x A-PRO controller overload after hitting too many buttons furiously when not nailing the take for 100th time, 1x opening a CWP moved to a different place, not bothering to allow Sonar to create the missing audio directory and 1x when deleting a Kontakt instance out of archived tracks).
 
Audio glitching is also a lot better (as described in my post above after the last series of updates from Dec 23, 2016). Knock on wood it stays like this. I rarely get a glitch/drop-out when working under load. Much of this is probably due to the improved driver (less interference with webUI) but I suspect also win10 had a fair share in that problematic situation (although no company officially comments on that really)
 
Recording also works fine - but I did have one odd situation where a simple piano scratch recording (only one stereo audio track plus MIDI) was completely broken i.e. the audio files could not be played back, hitting record again resulted in the same garbled mess (i.e. "digital noise") but restarting Sonar without any other changes immediately fixed it. So I believe this was a Sonar issue - although I have no idea how that happened as direct monitoring provided a crystal clear sound of a mediocre piano take and the recording itself was broken.  Back then I did not feel to break the creative flow for the sake of debugging, if this ever happens again I will ...
 
I will definitely hold on to my MOTU units as the AVB concept with its scalability, routing, recall various studio setups, etc options is just what I was looking for. Quality of the recorded takes in terms of super low noise floor is scary at times when you start to think how to edit/hide some real world problems (e.g. drum stool squealing)

It seems like you said you were getting more glitches with the Web UI open while using Sonar. Was that you?

yeah. that was me ... and that has been fixed by the beta driver ...

You are not alone regarding the glitches during playback....I stopped updating SONAR since 2016.10 - glitches started from 2016.11. Didn't improved in 2016.12, so I also rolled back to 2016.10 after trying that (I need to finish a project very soon). This was when WASAPI support was introduced btw...
I haven't experienced any corrupted projects though.

pilutiful

yes ... and win10 had a number of changes right about the same time ... but still I can't let Sonar off the hook, as fairly recently I did again have one odd situation where a simple piano scratch recording (only one stereo audio track plus MIDI) was completely broken i.e. the audio files could not be played back, hitting record again resulted in the same garbled mess (i.e. "digital noise") but restarting Sonar without any other changes immediately fixed it ...
