I wanted to share my experience with the E-MU 1616 cardbus audio interface, for the benefit of any future max pc/xp loopers who happen to encounter problems with the interface. I'm sure there are folks who are using this product with success, so this is not a negative campaign against the product, but only my experiences with the product with one particular system and app.
I bought this interface to run on a Lenovo (IBM) ThinkPad T60p (commercial/business class notebook), with 2Ghz duo core processors, 2gig of RAM, XP Pro, newest version of MAX/MSP, etc.
In short, I could not get the E-MU ASIO driver to perform with an acceptable degree of latency, and even though the Directsound driver functioned properly, it did not yield an acceptable latency either. I could get the ASIO driver to perform with minimal latency, but not without using MAX/MSP I/O Vector Size and Signal Vector Size settings, and ASIO buffer settings, that caused MAX/MSP CPU utilization to skyrocket into 80% and above, which is HIGHLY unusual and indicates something serious going on between max and the E-MU ASIO driver.
After several hours of phone calls with both Sweetwater Sound and E-MU tech support, the most acceptable conclusion at this point is that the E-MU ASIO driver and MAX/MSP are not playing well together...more reasonably that there are compatibility issues with the E-MU ASIO driver.
Long story short, I sent the unit back and am using a simple Edirol UA-25 USB interface (whose ASIO driver works perfectly fine with max with acceptable latency) for the interim, until I buy mac book pro on January and a RME Fireface 400.
I'm buying a mac, not because I believe it will perform better than my PC/XP notebook, but because I am interested in exploring a new platform (after using PCs since 1989) the expanded I/O options, and Core Audio system.
