Any takers on using two interfaces at the same time?

By definition, ASIO only allows a single audio interface driver to be running.
Some companies get around this by allowing several different audio interfaces to use the same ASIO driver.
In this scenario, the multiple audio interfaces function as a single unit.
 
You can use WDM to address multiple audio interfaces, but then you have clocking issues, higher latency, etc.
Not an ideal solution.
 
If you need 32-channels of I/O, consider a Behringer X32 with a Lynx AES-16 with AES-50 port.
The Lynx card provides 32-channels of I/O connected to the X32's AES-50 port via a single CAT-5/6 cable.
Super low round-trip latency... and rock-solid performance.
 
If you're not looking for an actual digital mixer, have a look at the new MOTU AVB series.
You can run multiple units under a single ASIO driver... to configure just about any type/number of I/O required.
Excellent fidelity, super low round-trip latency, rock-solid drivers

Thanks Jim I am still wrapping head around this topic but getting closer. For example based off your theory on ASIO because I have one 01v96i working fine using ASIO if I got a second 01v96i connected via ADAT I would use ASIO for both or would I need to use WDM?

I don't believe the Yamaha ASIO driver allows running two 01v96i units to double the I/O.
 
The O1v96i has a single Lightpipe I/O.
If you connected a second O1v96i to the first via Lightpipe, it's adding 8 additional channels of I/O to the first.
In this scenario, you're still only using the first O1v96i as an audio interface.
This would work just fine.  Probably not worth the expense of a second O1v96i for an additional 8 channels.
You can get an 8-channel preamp with Analog>Lightpipe (A/D) for a lot less.
 
If you're wanting to use two O1v96i mixers (both routed to your DAW - for double the I/O), your only option would be to run WDM drivers.  Both O1v96i units would need to share a common clock.  You'd have to make one the word-clock master... and the other the slave.  For the money spent, this is far from ideal.
 

Still trying to track the video down and will post it if/when I find it, but what it does is show the use of dual Tascam US-16x08 interfaces to provide 16 mic pres over a single USB cable. The US-16x08 defaults to a straight-through 8 mic preamp, feeding the 8 XLR inputs directly to the 8 line outputs, when no USB is present. The 8 line outputs are cabled to the second US-16x08's 8 line inputs (IN9-IN16). With this setup, you do lose the ability to directly plug a guitar/bass into IN9 or IN10. But we all use DIs with XLR outputs, right? 

One option is to add ADAT units for extra channels, if the audio interface supports ADAT. No need for running more than one audio driver that way.

multiple interfaces via ASIO works ONLY if the driver was originally designed to work with more than one device of the SAME brand.
 
Roland used to do this with the VS system that also tied into the Octa-Capture (VS-700 and OctaCapture together gave me 24 IN @ 44.1 kHz, 20 IN @ 96 kHz)
 
I believe RME provides this option for all their interfaces (??)
 
MOTU with their AVB series is taking it to usability peaks. 2 of these units just replaced my older Roland system, options are mind blowing (although I sat several hours figuring out the best way to route everything)

I am a fan of Motu to connect your motus which driver did you use?

I'm using the latest AVB PRO driver with the super low latency - although this still beta and some users have connections issues with it (which I only see rarely)
 
The "official" USB only driver supports the same features as regards routing, but at somewhat higher latency

You'll want to use the MOTU AVB ASIO driver.
 
MOTU has really upped their game with the AVB series.
The routing options are deep... so you'll need to spend some time working with that aspect.
Once you have your particular methods and routing sussed out, it's not hard to use.
You can also save presets of your routing/mixing configuration.
The AVB series is similar to a digital console... sans the tactile knobs/faders.
