Linux I don't actually have a reason for trying to build a Linux kernel with the CONFIG_PREEMPT_RT patch set. There's no way I can even measure the impact of it. Still, I felt like having a "real-time" Linux box, and set out to make one. Little did I know how difficult it would be to even get started.

That statement is just silly. Have you actually used the software I just mentioned. I usually do a lot of live audio processing with very cpu intensive plugins like impulse response. On other platforms, the norm seems to be to record with a raw monitor signal, and apply effects afterwards because the system can't handle doing this without using large buffers.

I might have a play with building an FX unit using a Linux box this weekend.

I have low latency pro-audio sound card already - just wasn't sure what software to install. What would you recommend for listening to line in and applying real time effects too? (last time I did this, I just did it in Ableton Live on XP - but there was around 32ms latency which made the thing impractical)

Rubbish. Try using Reaper under Mac/Windows. It can even run in Linux with WINE. I record live with FX on all the time. I also record ambient room with mic (so no FX required.) Truth is, latency is your enemy, so you need the right drivers for it to work with Windows (ASIO, though ASIO4ALL will work with standard cards), but Mac handles it fine with base system drivers. Even GarageBand will record live audio with FX. But honestly, you really need a real audio card. I use a Tascam 122mk2 personally. USB. Drivers work well enough. Low latency. Sorted.
