K9YC will point you to a couple of MIDI boxes from TASCAM and Numark
To expand on that, my testing and use is with XP Pro, and my focus was for I/O for use with RTTY, JT65, and other digital modes. BTW -- the boxes I've tested and use are USB, not MIDI. I studied the semi-pro audio market, bought simple stereo adapters from Numark and Tascam. Both use generic XP Drivers, and both work quite well for this purpose. Yes, they are 48 kHz boxes, and their dynamic range is modest, but it is quite sufficient for ham radio. I'm using both of them in my SO2R setup for RTTY -- the Tascam feeds one radio to one laptop, the Numark feeds the second radio to the other laptop. My testing used JT65-HF as a test bed, because it was the most demanding, and because it gave be the best on-streen readout of performance. I looked at the number of decodes per pass, as well as how well they decoded the weakest signals.
If you need to replace your existing Tascam, I suggest that you do what we both did before -- study the online catalogs of semipro audio distributors in your country (I buy from B&H Video in NYC and Full Compass in Madison, WI) to find a mainstream low cost product that supports Win 7. If I had to replace one of mine, it would likely be Tascam's box with the fewest features.
Note that we would use very different criteria to choose a sound card to use for spectrum display. I would look for one with a higher sampling rate and greater dynamic range.
One thing I looked at was the Pin One Problem, and neither the Numark and Tascam boxes have this design error. Last I looked, PreSonus stuff does. Behringer has earned a very bad reputation in the pro audio world for poor quality, poor service, and for stealing the designs of reputable companies.
