I don't think it is, but if so it will have to do with the driver and 
also how low a buffer the hardware is happy working with. MOTU can 
work with a 64K buffer, I believe, and PT's minimum is 128K (which I 
haven't tried yet - the 128K Stream Manager in OS 9 didn't work). 
Plus ESB has a little more latency than some other sound card drivers.

Now, that latency is for audio coming out of the computer, i.e. how 
long it takes between hitting your MIDI keyboard and hearing the 
sound.

The latency Gareth is talking about is when you're recording live 
instruments, which have to go through the computer; Pro Tools *TDM's* 
(not the Pro Tools LE systems') live recording latency is pretty much 
down to the converters themselves, so it's only a couple of 
milliseconds, like on a digital mixer.

***HOWEVER*** all three cards mentioned above - RME, MOTU, MH - have 
onboard digital mixing, so you can monitor the live input through the 
card and get the same 2.5ms latency. As a matter of fact, I believe 
those are the only three cards with that feature.

I don't know much about the Rosetta 800, but if as I suspect it does 
have standard native audio latency, you could use one of the above 
cards instead of its Firewire option - in other words, you'd just use 
the Rosetta as a converter and connect its digital I/O to the sound 
card.
