Appreciate the detailed reply, Chuck.  Very helpful.

Jim, thanks for your detailed reply.

Beta release.  V 1.2.6  -  Just announced and available.  32 samples at 96k - 1.9 milliseconds RTL on Windows boxes..  Now I need to hurry up and wait for the Thunderbolt 3 USB-C to Thunderbolt converter....   I will test the updates against the new USB firmware till then.
 
Take care

That's amazing. So just to be clear, that's with the MOTU connected via USB?
Which model do you have?
Ultralite AVB ?
 
Last question, is it usable under a reasonable load or is it a "pie in the sky" number great for advertising copy but clicks and pops with a single VSTi loaded?
 
Thanks!
 I found the release notes on the web site. Amazing numbers.
So has anyone tested this yet under real life conditions using USB and Windows?
 
 

No Steveo42, thats connection via Thunderbolt.  I can appreciate the pie in the sky number,  and cannot corroborate the information.  
 
I have a 1248 AVB - picked it up in July of last year I believe.  Its been rock solid in the current firmware release.  HOWEVER - I have only used 8 channels at 96k at one time.  I have a relatively new machine, and it has been just loping along.      
 
You might want to check out the release - there is a prominent button on the main page.  They didn't publish specs on the new USB changes - that's what I will be trying out first anyway.  I won't be able to try Thunderbolt until I pick up an adapter anyway.   

Thanks L Lyons! I'm going to load it up on my Ultralite AVB and take some measurements. 

Am I missing some sort of list for supported PCIe cards? I checked around, but either no such list exists - or - I am just completely missing it.
 
Does anyone else have any suggestions for a TB/PCIe card?

There are no 3rd-party PCIe Thunderbolt controllers.
 
Some motherboards have an optional "Add In Card" that provides Thunderbolt 2.
This won't allow you to run "PCIe via Thunderbolt" drivers.
 
To run "PCIe via Thunderbolt", you have to be running one of the absolute latest Z170x or X99p motherboards that offer Thunderbolt-3 via USB-C port... and you have to be running Win10.
Microsoft don't support "PCIe via Thunderbolt" with Thunderbolt-2 (thus the AIC controller cards are no solution).
 
NOTE:
If you've got Thunderbolt-3 (via USB-C), you'll need a USB-C to Thunderbolt adapter to use a Thunderbolt audio interface.  Several of these have been announced.  None are currently available.
One is supposed to be released the 20th of this month... and will cost ~$80.

Thanks Jim - I just had a power supply meltdown in my PC last weekend, so a new machine (or at least a significant rebuild) is already in my future. I'll keep an eye on those MOBO options. Much appreciated.
