Hi,
Oops, sorry I thought we were talking about sample rates :)
I was referring to the Presonus 1818VSL, the basic hardware is USB-2 class
compliant and works on Linux, the trim/gain knobs on the front are also
operational as hardware. On Windows/OSX the Presonus driver has DSP
Plugins that are operational in it's Graphical Mixer application so you
have EQ and compression within the unit itself that is accessible without
needing a DAW. I've even seen people use the 1818VSL with Windows as a
Live mixer and with all that software DSP it works quite well as a Live
mixer. There is no Mixer app on Linux that accesses the built-in DSP
unfortunately but even just being used as hardware the unit has good
quality quiet preamps.
In my experience a full RT Preempt kernel is a necessity to get the
latency down to 512fpp or less, with standard issue lowlatency kernels,
even tweaked ones like Liquorix anything less than 1024fpp X-ran like
crazy.
So to summarize, the preamps and trim pots are available as hardware, the
extra DSP is available as software in Windows/OSX drivers only. All in all
I think this is one of the best 8 channel I/O options for Linux Audio
users.
Best Regards, Glen

Thanks for the comments, To be honest I've
never even tried to work
with 192, I'm a 44.1 guy all the way :). Perhaps other Presonus users
could be more enlightening. It is a shame all the nice integrated
channel dynamics UI goodies are locked away from Linux users :/

Since I do not know the Presonus interfaces, I did a search when you
mentioned it and got the 192. Haven't checked back if that was the one
you actually mentioned :)
From your comment the interface works under Linux at the hardware
level, with possibly none of the preamps available. Is
that so (for the 1818SL that is) eg. the front knobs are not for the
preamps ?
Cheers.
