I'm installing all of my music software and hardware on a new computer. I use the ADAT I/O on my 1818VSL to route audio to and from my eurorack modular using the Expert Sleepers modules. This worked perfectly in my old computer. But now that I have installed the 1818VSL driver on the new computer (an HP EliteDesk running Windows 7 -- and yes, the old computer also ran Windows 7, though perhaps not the exact same version), it appears the ADAT outputs are misrepresented in the Windows OS.
If I open the AudioBox app and look at the mixer, I can see that the audio from the modular is indeed reaching the computer just fine -- the channel meters in the app respond to what I'm doing in the modular. However, Reason shows the ADAT channels that are available as audio track inputs as ADAT 9-10, 11-12, 13-14, and 15-16. There are, of course, no such channels. The AudioBox app shows these channels correctly as 1-2, 3-4, and so on. Reason can't see 1-2, 3-4, etc., as available inputs.
How do I fix this?
