TOPIC:

I have a MCH Streamer which I want to use to connect a Win7 PC to digital mixer via ADAT. I want to output Adobe Audition as 8ch multitrack or some stereo apps on different stereo pairs of the ADAT. My apps do not "see" the single channels but only a single device "MCHStreamer Multi-channels". Do I need a different driver?
One of my apps is created with Visual Basic and the BASS driver, is there a setup for this driver?

I'm seeing a similar issue with UDIO-8 for some, but not all, audio applications, ie., the USB AES device appears as an option, but not the individual channels. Did you ever find a solution? Thanks. 

The UDIO8 will always show up as an 8ch interface in your OS. I'm afraid that it won't show up as pairs of stereo interface that can be accessed by various software. 
You might need to use some routing software if you want to use multiple units .e.g JackAudio maybe? Or some virtual cable ASIO device?

I don't understand. The device should allow 8 AES inputs and 8 AES outputs. Using Adobe audition, I can see the presence of these miniDSP channels and selectively choose from the device's 4 stereo or 8 mono inputs (selected as devices within Adobe Audition) as well as choose which of the 4 stereo AES outputs I'd like to use. Perfect.

In other software (notably SAM Broadcaster), I am not seeing these options. I'm only able to select "USB audio" without any explicit ability to choose the channels the software should use. 

When we use other devices, PCI sound cards or USB interfaces, we're accustomed to seeing all of the available I/O provided by the device in the audio software's menus. Why would this be otherwise for UDIO-8? 

I did find a solution. I had not understood that the MCH WDM only seems to allow the first two channels of the 8 to be accessed. (Maybe the same problem as described by slbradio?) Also that my version of Adobe does not support ASIO drivers, only WDM. (It's pretty old!). So I found that BASS has an ASIO driver (including some bugs, now fixed in the latest release) and I re-wrote my s/w using this and it allows me to access all 8 ADAT channels of the mini DSP both as stereo pairs and mono.  Also that Reaper (Multitrack recording s/w) is ASIO compatible.

Most likely the difference between ASIO vs WDM as already correctly suggested from above. 
How about asking that software supplier if they support ASIO?

Thanks to you both; we'll investigate further per your suggestions and report back.
