Windows 10, Focusrite 6i6, Melodyne nightmare

1) Uninstall mix control
2) Reboot
3) Install mix control
4) Reboot
5) Go to mix control, reset the hardware and other settings to the defaults
6) Set up mix control again...
7) Save any settings you have to hardware (assume there's an option there, there is with saffires).
 
Other things you might try:
 
A) Update your BIOS
B) Update your chipset drivers on Intel driver update website.
C) Update your display driver
D) Run windows update.
E) If you are running or have run ASIO4ALL in the past - remove and uninstall it now!!
F) Temporarily disable your virus scanner and disable your network adapters.
G) Delete AUD.INI in Sonar (google for details)
 
Cheers...

A single project...
 
OK
 
Try PDC override.
Try ruling out conflicting plugins.

You could try bundling and then unbundling the project to see if it clears anything..
Worst case scenario. Create a brand new project and copy and paste your data from old into new...
Ta.

Thank you, I'm not sure which plug in did it, but after eliminating, I am now able to open without crashing.
 
However, there is still something amiss in this project--it almost seems like something is either looping, or using up too much processing power, even though processor only shows 32% and most of my tracks are frozen.  I can't see anything obvious where I have looped...channel strips are feeding buses, effects sends are feeding effects in a bus and buses are feeding the master.
 
The symptoms are: slow loading, sometimes clicking (even though I have adjusted the ASIO settings), which does disappear after a few seconds; also, sometimes upon boot up, I will get a click and a surge and my master meter will pin in the red and I have to re-start. There also seems to be somewhat of an overall reduction in level, and a little extra latency that is not present in other projects.
 
I came across something like this before, and I would like to figure what I might have done wrong so I don't keep doing it.  If you have any ideas, I'd appreciate it.

Why bother going to Win 10?   What are you really gaining?   Is it really worth the trouble you are having with your HW and you haven;t even gotten to any plugin or software issues yet....   Personally,  I did the Win 10 upgrade and immediately had issues with Firewire and some other things so I just reverted back and I am as happy as can be as my system (computer AND software work perfectly on Win 7 as they have for quite sometime).   I stayed with Win 7 as it will e supported through 2020.   I can't imagine Sonar Platinum  stopping Win 7 anytime soon and even if they did... what more can they possible give us that would make our recordings sound any better (or worst)?   It already can do SO MUCH!  So again.. why bother?   Just wait until you HAVE to move (i.e. machine obsolesence etc) and by then there will be a whole new set of tools and toys!

Even if Windows 10 wasn't at fault with your Sonar project issue, its still an epic privacy, self-determination and computer ownership violation.
 
Microsoft would like to start treating YOUR computer like its theirs, control it, lock it down like its an Xbox or PS4 console. Windows 10 is another major step in that direction. Among others:
 
- UEFI may have some useful and needed improvements over the old BIOS, but this modernization has also been misused to introduce various measures that offer more control to OS and hardware manufacturers and less control to actual computer owners who paid good money for that plunder. 
 
- Same as Intel's in-hardware security features baked into all their recent CPU's amount to nothing but omnipotent back-doors.
 
 
I will be upgrading to Win10 only after about a year, when drivers have been optimized and privacy software packages blocking Microcruft's tentacles have matured.
 
Not like I even have anything for them worth seeing, but one's gotta have some principles, especially in the face of a slowly creeping process that isn't going to stop if everybody just takes it.
