Hi Seth, Thank goodness I found this site and have now registered as a newbie (so please be gentle with me! :-) ) I hope you can authoritatively answer this question for me... I have an old Carillon professional Audio PC running WIndows XP on a pentium 4 3.4GHz CPU with 4Mb of RAM. I am running Sonar 3 Producer and have an external Edirol DA-2496 24Bit/96kHz 8-IN/8-OUT Digital Audio Interface box and corresponding PCI Card in the PC. Despite being an old PC and operating system this still works well. (I keep my bios, XP etc. 'tuned' so it still runs well despite its age.) However here's the thing; I would like to upgrade my PC to run Windows 7, however Roland do not have a Driver for this PCI Card to run on Windows 7. I am very loathe to ditch my external Edirol DA-2496 DAI as it still works perfectly well and cost me a pretty penny when I bought it. However, as a means to getting it to run on Windows 7, I would be happy to buy an updated PCI SoundCard if I could be GUARANTEED that this would work on windows 7 with my external Edirol DA-2496 DAI box. This lack of a Windows 7 Driver is the ONLY thing that is stopping me upgrading from XP to Windows 7... QUESTION: Is there a Roland (or other?) PCI SoundCard product with Windows 7 Drivers that you can recommend that you would GUARANTEE will work with my DA-2496 DAI box? Thanks in advance for your help. Malinki_Malinki.
