Trying to see if it works with no problems for anyone using a Windows OS computer.
 
Thanks

I have been successfully using an Apollo Twin Duo USB with my Win 10 Pro x64 DAW and SPLAT/CbB x64 for several years now. I also used an Apollo 8 SF Quad FW for several years before that (sold it  on Reverb when I went to USB) and will probably upgrade to the latest Apollo X8 TB3  sometime next year during one of UA's regular promo deals. I also use several other x64 DAW's (REAPER, Studio One 3, ACID Pro 8) as well. They all work well with the Apollo/UAD plugins using it's ASIO/DSP x64 drivers. Pretty much plug and play.

Yes, the Apollo series USB or Thunderbolt-3, both work well with a well-configured Windows machine.

If you've got a Thunderbolt-3 port (and don't need the UAD plugins), the Presonus Quantum should be on your short-list.  Quantum yields amazingly low round-trip latency (1ms at 96k with a 32-sample ASIO buffer size).
If the UAD plugins are what you're after, the Apollo series and the Unison DSP will allow you to play/record thru their plugins at ~2ms latency.
 

Thanks Jim and Billy,
 
I found a Gigabyte motherboard that has Thunderbolt 3 built in, so with that I can use the Apollo interface without having to use a separate thunderbolt adapter for Windows OS.

one more positive comment - I've been using UAD with Windows since it first came out, and the Apollo Twin USB since it came out, and I've had nary a problem that wasn't self inflicted.

I really want to upgrade to the x8, but that means a new machine, and orphaning the Apollo Twin USB. The new machine is not a huge issue financially (well, the whole upgrade will be pricey), but I am NOT looking forward to rebuilding the DAW.

There is some benefit to the exercise, stuff I never use will be removed, but it's tedious and time consuming.

And I'm both cheap and lazy...

Make sure you know all the details about Thunderbolt-3.
 
Most Thunderbolt audio interfaces are Thunderbolt-2 (including the Apollo-8).
If the audio interface is Thunderbolt-2, you'll need a Thunderbolt-3 to Thunderbolt-2 adapter (Apple and StarTech both make adapters).  
 
If your motherboard doesn't specifically come with Thunderbolt-3, you can't just add it to any motherboard.
The motherboard specifically has to have a Thunderbolt-3 header... and support in the BIOS for that particular Thunderbolt Add-In-Card.
 
Thunderbolt-3 connects via USB-C port.
USB-C can carry USB-3.1 or Thunderbolt (this is where it can get confusing).
Many motherboards have USB-C port/s... but don't have Thunderbolt-3.
If the motherboard doesn't specifically mention having a Thunderbolt-3 controller (or support for a TB3 add-in-card), it doesn't have/support Thunderbolt.
 
Microsoft only supports "PCIe via Thunderbolt" with Thunderbolt-3 controllers.
If you have an older Thunderbolt-2 controller, it won't work.
Older Thunderbolt-2 controllers that are currently being used with Thunderbolt audio interfaces are running "Firewire via Thunderbolt"... not "PCIe via Thunderbolt"... which is necessary for PCIe level performance.
 
Microsoft only supports "PCIe via Thunderbolt" with Windows 10.
 
Make sure your Thunderbolt audio interface specifically has a Windows 10 driver.
Some are Mac only.  Don't assume
 
 
 

I use an Apollo 8 and and an Apollo 16 on my Windows 10 machine with Thunderbolt (plus an Octo PCIE card).
 
Hasn't always been smooth but it is now very reliable. Updating is sometimes a pain - you have to uninstall the old software, and then manually uninstall the drivers and reboot before reinstalling. If I don't do that, stuff doesn't work right. :/
 
I get prompted to update my firmware too often and have resorted to deleting the firmware files from the PC after an update. I even sent my unit in and they couldn't figure out why that was happening, but I've learned to live with it.
 
Overall, I'm a fan of UAD and I have no intention of changing my interface or my OS.
 
Now, I did spill water on my motherboard Friday and we're in the process of figuring out all that was fried. Hope that Octo still works!

Ouch!

I've got an Apollo Twin Quad Thunderbolt that works fairly well but seems to have too many audio drops for me to say it's great. Of course, I use my self-built somewhat high-end computer (TB3) for everything, not just music so maybe that's why it has performance issues. I also have lots of hard drives. An ssd for windows and then a 4 TB for main storage plus 2 other HD's for backup.
 
My biggest complaint is that I have trouble recording the midi performance data from my Roland drum set without turning off all the FX in the project and using a 128 buffer (which is too slow for my ears). My old Roland OctaCapure could go down to 32 buffers (almost no noticeable latency) and rarely crashed and I could keep all the FX on. I keep asking UA and Sweetwater (where I shop mostly) to help me figure out the problem, but so far, no solutions. Had I known the drum performance would be troublesome, I don't think I would have got into the Apollo world. In fact, I just bought a bunch of WARM stuff, EQ, 2A, 1176 and a new 47 mic that has a huge buzzing sound. They are sending me a replacement tomorrow. Of course, I didn't even know these pro-level hardware units even existed until I got into Apollo. Maybe it's time to sell the Apollo, hmmm...
