Does anyone know if Roland has made as compatible driver for the Octa-Capture Audio/Midi interface yet?  Since they have an entire line of the Capture products, I wonder if they are waiting a week or so before they are released.  
 
Has anyone installed Windows 10 Beta to see if it compatible with the Octa-Capture??

They sent me an email last week stating that the current driver wouldn't work in win 10 and they plan to release one asap. Saying that, I've seen a post or two in here stating that they do work.

what's the point of having win 10 if nothing works with it?
 

Well I just put windows 10 on my desktop today, and I can confirm the drivers do not work.... 

Info on Win 10 drivers:

Looks bad for me. I have a UA 25 EX.

Ouch! it doesn't work now.  I had my Studio-Capture installed in an early Preview version but never checked it in the later or the final 10240 version.   The early Preview version must have been more 8.1 than 10. 
 
The Studio-Capture gets the same Code 28 error that the Roland/Edirol PCR MID keyboards do in Win 10.

Hey it works, i installed windows 10 and installed the octa-capture driver in win8 compatible mode. 
But the latency is bad on win10, on win8 with 256 samples i have a latency with 6.9 and with the same 256 samples i have a latency of 9.6ms on windows 10, and it uses more ram than win8. So i still will stay on windows 8.1 ;)

Looks like drivers are up for the Octa-Capture:

The Octa-Capture drivers are up but NOT the Studio-Capture or the PCR MIDI Keyboards.
 
 

As it turns out, the Octa-Capture has been changed to a "plug and play" device and Windows obtains the driver, don't have to do an install like Win 7/Win 8.1. 
 
I tried the Studio-Capture with the "plug and play" mode and it still fails so they haven't updated it yet.  Surprising considering Roland advertises it as their "flagship" recording interface.
