FWIW the Focusrite 3.4 Mixcontrol DOES work perfectly with W10.

Focusrite recommends not to upgrade with saffire and VIA chipsets. I can confirm this issue.

+1 Focusrite Pro40 & v3.6 working well here !

Well I finally tried out Windows 10 on one of my Music PC's, I just done a test with a cloned disk just in case, and can report that my M-Audio Delta 1010's (OLD) seem to work flawlessly under Windows 10 :) Using the latest/last driver 6.0.8 which was for Windows 7. Now if I can just find a way to come to grips with the look of the thing, I'd be ready to jump ship from Windows 7
 
I've upgrade 4 machines now, 2 laptops 1 test machine and 1 of my main DAW machines, rolled back 3 of them to Windows 7, and must say that the upgrade process and the rollback process has worked smoothly and flawlessly on each occasion, which I thought was very good.

FWIW
 
M Audio FireWire 1814 is working in Win 10 x64, with Win 7 drivers. 
 
Anyone had success with Yamaha SW1000XG? Not holding my breath...

I just want to chime in here with some info regarding the legacy M-Audio Firewire 410. I originally purchased it to use with a laptop, but since then, it has found a home on my desktop DAW :-)
 
I do not have info on any other M-Audio products, but I have run across this thread on the M-Audio Community as I was researching the state of drivers for this particular legacy device.  I am running the latest released drivers for Win 7, but there are reports in this thread that the Win 7 driver actually also works on Win 8 and Win 10.

Here is my humble opinion about the rush to upgrade to Windows 10, from somebody who has been building computers for 15 years. 
 
I just don't understand the rush. Windows 7 works well.  It will be supported until 2020. 
 
Windows 8 works well, but I do understand that some folks cannot stand the UI. OK, but why would you want to risk the stability of your working Sonar rig to have the latest and greatest OS?  An OS is only as good as the applications & drivers that run with it! Give the hardware vendors and driver developers time to catch up!
 
You have a full year to grab the free version of Windows 10, so nobody is making you do this right now!
 
Rant off... Hope this info is useful to anybody still using the M-Audio Firewire 410 :-)

No rush for me, that's why I am running Win 8.1 for my DAW. I won't upgrade till next year probably. In the meantime I've got a Win10 OS on dual boot so I can make sure everything will work before I do so.

I'm testing windows 10 on my DAW now. I'm using an Echo Audiofire 4 with the latest drivers. I was on Win 7 and these are the same drivers. On win 7 I was running 64 samples with the network disabled. On win 10 it crackles and pops and then crashes the system. I never had win 7 crash due to a driver lagging so I'd say win 10 isn't as stable as 7. It did crash much more gracefully, that's an improvement  I changed to 96 samples and it runs fine with the network running. That adds a couple ms of latency, but it's not a problem for me. I haven't checked performance setting yet, it's possible that the system will need to be optimized for the new OS.
 
So Echo Audiofire 4 runs with the latest drivers, but it seems a little slower.

 Mine wouldn't work with the old Intel P4 boards.  I still have an old Gigabye AMD socket A board with VIA chipsets that could still run it.
 
 M-Audio FW410, AP192 work on Windows 10.  I had to roll back a bad W10 upgrade but the interesting part was my Terratec EWx/2496 worked with Vista beta 64 drivers.
 
 I find it odd that those using W8 have problems with devices in W10.
 

M-Audio Firewire Audiophile works fine with Windows 7 64bit drivers. I had to reinstall the driver after upgrade.

Why did you have to reinstall the driver?
