I tried N-Track. I'm a registered 24-bit owner. I really wanted it to work, darn it! It kept crashing on me. For example, I'd be recording 8 tracks at a time successfully from a MOTU 2408. I'd switch to recording just one track and crashola.
I've ended up much poorer with Cool Edit Pro and Sonar. Stable system. Neither one supports VST directly, but both support DirectX, and there are several different wrapper programs that wrap VST into DX compatible plugs that work well.
Both CEP and Sonar support low latency WDM drivers (although certain WDM drivers don't seem to work well with CEP). Neither one supports ASIO drivers.
I really like N-Track interface and feature set. I just wish Flavio would back off for a release or three and concentrate on stability, stability, and stability.
The reason I use both programs is because Sonar is better for multitracking and mixing automation while CEP is better for wave editing. Combine them with the Ozone2 plugin for mastering and its looking pretty good.
N-Track has the potential to be a killer program. I'll keep poking my head in to see if its stability has improved, but when I've got a band laying tracks down, I don't want to EVER have to say again "Just a minute, I have to restart the program!".
I see posts from some folks that seem to have nailed stability on N-Track. I'm glad they have. I tried and was not able to get it to work. My system is quite standard though, and both CEP and Sonar are absolutely rock solid on it, so I believe N-Track should be too. I'm running a 1.6 gHz P4 on an Asus P4b266 motherboard (Intel chipset), and a MOTU 2408 interface. My OS is a tailered Win XP Pro (lean and mean for audio recording).
May your N-Track always be stable, and your singers on-key!
