Bought in 98. It was the only one at this price which provided an external rack housing, eight inputs and a comprehensive software package.
Use: home studio for guitar and keyboard recording
Computer system: CPU AMD Athlon, 1 GB Ram, two hard drives, dual boot with Win Millenium (for the Isis) and XP.
Installation can be a bit tricky, but it works if you use the latest driver version (somewhat old) and follow the procedure.
The only problem is the lack of support for XP. That's why I use a dual boot system with Millenium for the sound card. Stability is not an issue, the system never crashes.
I use it with Cubase Vst5, Acid pro and Wavelab
I record only audio, no latency problems.
After so many years with my Isis, I must admit that it will be difficult to part with it.
When I bought it, it was a very good product. It's a pity that there is no XP support.
I would buy it again.
I created an area dedicated to the Isis on my homepage. Visit it and tell us your experience.
