Try.

1. Delete AUD.INI (google for details).
2. In Sonar preferences disable arm changes during record.

Thx.

I've updated to Win10 64bit to get the updated driver for the OctaCapture, everything was seemingly playing nice when (mid recording, not on a transport stop)...

Unlabored with only four tracks, 2 MIDI coupled with analog voices and two straight analog.
I dunno, ...obviously beating my head against a tree in the woods didn't help at all, ...maybe I'll go lay down...
I did the tune with 6 tracks in audacity just fine earlier Saturday, maybe that's the answer, but I will miss those wonderful toys!

I am using window 8.1 with Sonar X3e, and the Octa-Capture with the latest drivers.
I use Sonar strictly for live performance playing back tracks. I am very suspicious of Oct-Capture. Some weird things are happening, such as the USB connection stops responding for no apparent reason. I'll have to reboot and then everything is fine for the rest of the show. This happens randomly.
I have a fast dual processor laptop computer with SSD drive 6 Gigs of ram. It's definitely fast enough, up to date with everything. All connections to Internet are disabled. Windows update is disabled as well as the windows virus protection program. Basically I have nothing running in the background. Sleep mode disabled etc.
Also I've tried to use the direct monitoring of one vocal channel, while playing back tracks, and it turned into a nightmare.
Just thought you should know.

P.S.
Have you tried this.

Wow, don't see how I missed your post, I did delete the AUD.INI before, something CakeAlex got me into the habit of doing a few years back. I didn't do it with the new upgrade though. I did (had to) to and update of all the XLN stuff, Drums and Keys, and I also checked CCC for updates as well. I have since dumped the SI from my templets,(and the hanks continue) frankly the strings on my Fanthom are just as nice or better.  I'll give the AUD.INI rebuild another try. I think I'd rather go back in the woods and bang my head against a tree some more before the reformat and reinstall of everything. I know the DAW software is huge and consuming, I just thought it would be easier than this to get it to work.... Thanks again for your time and effort!
FWIW I hear a small static snap each time I hit the record key, not sure if that's incidental or coincidental, and also, I haven't noticed before, but the Place Marker for lack of a better term, doesn't follow the record line, it just stays at the 'home ' position, The triangular marker on the top timeline. Maybe its not supposed to, but I thought it used to..

I am glad it is working better. I catch this thread on my phone so can rarely type, but the thing that caught me is the "reformat/reinstall" comments. Please realize that those are extreme, last resort measures (and rarely help unless you are purging the registry and loading the machine differently). Do not make extra work unless forced to.
 
Plus it saves trees from excessive damage due to head banging!

If you've just installed Windows 10 it won't be "snappy" for the first few days...

You don't need to delete aud.ini again that's not going to do anything...

Just pasting in some generic advice here...



Advice is generally (no particular order)...

1) Update audio interface drivers and firmware to latest. I strongly recommend removing old version and rebooting afterwards. Then when new one is installed reset the settings everywhere on the interface.

2) Temp disable your virus scanner. Before you do that though scan for your system for viruses and malware. Ie with AVG and Malwarebytes.

3) Make sure your audio interface is disabled in windows control panel sounds

4) Make sure the interface is plugged in USB2 socket. Not USB3.

5) Defrag. Don't use third party defrag utilities that monitor your system.

6) Update your display drivers

7) Update the rest of your drivers and firmware everywhere. eg controllers.

8) Disable unnecessary startup programs and services. Remove unnecessary applications from windows add/remove programs. Google and research this. Warning do not disable security features.

9) Update your motherboard chipset drivers (try Intel driver update site) and BIOS

10) Check windows event viewer for bugs.

11) Try deleting AUD.INI (google for details)

12) Check windows device manager. Can you disable any drivers you don't need? eg HDMI drivers.

13) Check task scheduler to make sure nothing is running whilst using your DAW. Google 'windows event viewer' for further details.

14) Make sure CPU in windows power settings is set to 100% for  min and max. Optimize your drivers for power management.

15) If you have ASIO4ALL remove it!!!

16) Tools latencymon, process monitor and process explorer are your friends here.

17) Run windows update!

And always backup

Event viewer is read only it's just a viewer. You are looking for the red icons and crashes with sonar.exe esp.

Don't worry about windows update in win10 sorry it's gonna keep you up to date whether you like it or not nowadays..
