[No longer relevant] Sonar and a Focusrite Scarlett 2i4 USB Audio Interface?

I do have it and it works like a charm, go for it

Good to hear. Are you totally happy with noise (as in quiet!) and latency?

Grum.

I've got the 2i4 and the 8i6, both have worked very well for me.

Good to hear . I'm getting the feeling the 2i4 could be the one.

Grum.

I went with the 6i6 for reasons I go over in my review. 
 
There is no tracking latency with any interface as they all use direct monitoring. Tracks are perfectly in sync. 
 
 

Sorry your sort of wrong on one point unless I'm misreading - Your interfaces inputs are analog and the monitoring system is too. It's exactly the same as with a mixer.
Maybe your talking about the DAW playback audio coming back to the interface?  Sonar automatically compensates for the system latency and there should be none at all as far as overdubbing a new track goes. So your interfaces input will always be dead on with the DAWs tracks. 
 
You can check this buy performing a loop back test. 
Send a Kick or snare drum track out and then patch it back to an input and re record it. Zoom in on the transients and you should find them perfectly lined up. If not, then you may need to adjust Sonars compensation settings but I think this is rare with any proper audio interface with good drivers. 
 
People are always misinformed about latency and when and were it really matters. 
 
For me with a so, so set up I only hear latency when input echo is engaged.
MIDI latency gets worse if you add certain plug ins like LP64.

Is anyone out there is Sonarland using one and if so does it bring happiness and good results?

Grum.

Yes , I have and use the 2i4 . it is a very good unit for what it costs ...
the input pads are definitely a must have …
i do a lot of recording direct using a large variety of my personal guitars 
the input pads will give you a nice sweet spot where you can get a correct gain staging while still maintaining  a fair amount of headroom …
i play very dynamicaly ,  having the input pads come in handy for the phrases that i happen to dig into.
 
the mic pre's sound impart an almost HI Fi type of vibe / sound ,
before I got my 2i4 I ran a pre into my PCI sound card …..i have no need for it now …the pre is in my closet ….
 
I like that the 2i4 has an extra set of out puts …Focusrite touted that feature for the DJ's out there ….
I'm not a DJ  yet, I feel having the 2 extra outputs  is a nice additional feature  to have ...
 
hope some of that helps, 
Kenny

Most (if not all) interfaces pass incoming audio through the convertors in the hardware before handing it on to the output. They take the PC out of the routing, but not their own convertors and digital internal mixer. This is why the more honest of them (like Focusrite) talk about "near zero latency" monitoring. Nowadays the internal processing is so fast it nearly always doesn't matter. Take a look at the block diagrams many interfaces come with, and the analogue inputs and outputs are both attached to the convertors.

Unless the interface has built in extra "safety buffers", on top of the ones the driver allows you to configure, which the driver fails to report to the DAW. This seems to be more a feature of USB interfaces than Firewire or PCIe. Then there are a few interfaces where the reported and actual measured latencies seem to bear little relationship to each other at some settings.
 
Oblique Audio's RTL Utility is a useful free tool for testing interface latency if you've not come across it. Easier than looping audio from a DAW, means there's no DAW internal calculations affecting the result and lets you run through loads of different latency settings very quickly.

It matters when it gets in the way. Exactly how much latency causes a problem varies from person to person and even the instruments in question.

I think you mean audio latency? At least, that's what the help and manual describe plug in delay compensation as. If you use a VSTi synth then yes, there will be more latency between pressing a controller key and the sound emerging, but I suspect Sonar spits out MIDI at the "normal" time then delays the audio output from the VSTi - since audio tracks have to be delayed as well that would seem the easiest way to do things. I'll be honest and say I've never actually checked this though, I rarely use VSTis other than drums from time to time and avoid latency inducing plugins while tracking because I generally monitor via Sonar so it's not something I've given much thought to. I'll have to see if I can come up with a few experiments to find out what happens to MIDI with pdc active.
 
Hm. We seem to have drifted well off-topic....

Yes, latency is the crucial thing if you need to monitor via a DAW, yet like guitar pedals and manufacturer claims regarding their bypass it can be very difficult to seperate marketing speech from hard information.

And just because an interface is capable of e.g. 48 sample round trip times doesn't mean that the computer someone happens to have is capable of running it at that glitch free. Once we had to worry about tape machine running speeds, bias, print through on spools, cleanliness etc. Now we have to worry about PCI bus latency, BIOS tweaks, cpu sleep states etc.

Once in a while I think the old boys back in the 1930s who just set up a bunch of direct to disc recording machines, pointed the horns at the musicians and recorded the performance direct then repeated as many times as they needed to maybe didn't have it so bad after all.
