Multiple Soundcard Drivers / Mutiple Recording Rates.

I have an M-Audio Fast Track Pro connected by USB to my laptop which has a Realtek built in card. The Realtek sounds great and actually has higher resolution (192Khz/24bit) compared the M-Audio (96Khz/24bit, or 48/24 with 4 channels). I'd like to be able to use both soundcards simultaneously to maximize I/O channels but the Realtek isn't visible in Sonar with ASIO selected, MME(32) has awkward latency issues which preclude echo monitoring. I'm wondering if there's any way to assign different drivers to the different soundcards i.e. ASIO for the M-Audio and MME for the Realtek.
 
I also have a Delta 66 but that's a PCI board in my desktop which isn't up to spec to run X1 but will run Sonar 5. What's my best option for maximising the of useable audio I/O whilst minimizing latency on the laptop which is an i7  running Win7/64 with 4GB RAM.
 
Also whilst on a similar topic.... Anyone know how/is it possible to assign different recording sample/bit rates to individual recording tracks (so that is the rate they record at)?

    The ASIO standard doesn't permit multiple device drivers so it won't work.

    With MME and WDM drivers it is possible but audio cards need a clock for setting and keeping a steady sampling rate. One card can't keep the sampling rate for another without some hardware between the 2 eg clock IO. It's a topic that frequently comes up. 

    Some folks try using the ASIO4ALL driver with mixed success. It provides an ASIO driver wrapper for WDM drivers and does provide a concatenation ability but having experimented with it myself find that it wasn't worth the hassle.
     
    While your onboard card is capable of 192/24 don't believe the notion that it will produce better sound quality. Your M-Audio card has far better specs when all the factors are considered. 

    If you must have more IO then there are quite a few modestly priced cards that will do the job.

    Things like Cakewalk/Roland's own Quad Capture andante others.

    Cheers mudgel I basically feared there wouldn't be good solution without more outlay and yet more redundant hardware!

    Any ideas on recording at different rates on different tracks? (I have various reasons why I'd like to be able to do this.)
