Focusrite's unparalleled pre-amp legacy forms the foundation of this new interface, with eight award-winning Focusrite pre-amps. These are combined with the very latest in firewire interfacing technology to deliver seamless integration, excellent routing flexibility and future-proof, rock-solid driver stability. With Saffire PRO 40, sonic integrity reigns supreme. The eight Focusite pre-amps ensure low noise and distortion, whilst quality digital conversion and JetPLL(TM) jitter elimination technology ensure pristine audio quality as your audio flows between the analogue and digital domains.

In case someone cares - we got this last week. It is hooked up to a '2007 MacBook (Intel, the white one, OS X 10.6.2). We'll also try a MacMini with 10.5.8 and another with 10.6.2.

Out of box I noticed that CSA (Canadian product safety) seems to have "specially treated" our box and the 90-250 V rating has been blacked out + some CSA stickers over screws. Not sure that they have really changed anything, they might just not like the 90-250V spec for Canadians... I have written to tech support in UK to ask about what this really means.

Hooking up was easy enough - the Mic Pres work, the line ins too. Enough gain to hear an Ant cough in the basement.

The routing and mixing options are really nice - the manual is crap, though. If I didn't have a basic understanding of how mixers work, I might have needed days to figure it out (thanks to Tweak for excellent explanations about routing, too!).

I haven't tried any of the ADAT or S/PDIF options yet, nor the MIDI (the piano has USB MIDI and I don't have regular MIDI cables)

No DSP on board, so some time in the future I will try to route through an outboard reverb and see how that works (as long as all my inputs aren't full).

The software update was the first challenge - although the installer asks for administrator password if started on a non-admin account, it silently fails. I had to run it from an admin account. It updated the firmware of the interface, too.
The next problem was the new Mix Control 1.7 application - it would only run on the admin account - reason were screwed up access rights in the application bundle. After setting the access rights of every directory in the bundle + the main binary to execution for all (you can do this in finder, but it works faster on the command line) it works now for all users. Wrote another ticket to tech support.

Don't expect a sound review from me - I have no reference or experience whatsoever, I can only say it sounds amazing in comparison to the onboard sound (otherwise i'd return it )

One issue on the Mac might be the Latency - the driver seems to allow 256 samples as smallest buffer. Not sure, though, as the software won't tell - they just call it "short" "medium" "long" "very long" (another ticket to tech support). Judging from the documentation, the windows drivers might be different. When using software monitoring, only "short" is acceptable and inaudible (snipping fingers). For the piano higher latencies seem to be OK for my girlfriend. Routed monitoring through the Mixer application is instantaneous for my ears.

Has anyone tried out this interface?

reading the specs on several websites I see it is an very impressive interface by matching focusrite preamps with nice converters...

but... does really all that results in real live stunning performance or just marketing tricks?

Please someone postttt!

Anyone have it? Inquiring minds need to know...

Hi,
I also wanted to know about this interface. I have a Macbook pro and am planing on getting a firewire interface.

I am going back and forth with the Saffire pro 40 and the new impact Twin. Any ideas?

I still own it... we have made some recordings by now - recording 5 Tracks including software montoring through some plugins (I don't have more inputs) with Ardour or Garageband works fine on a white MacBook (2007), no Firewire or CPU bandwidth issues although the CPU does get visibly (and audibly) loaded.

Being able to split monitoring chains for instruments onto the speakers and microphones onto headsets only through their software mixer really is a plus (everything is in the same room). Although normally we don't record microphones while monitoring instruments through the speakers, setting this up properly helps protecting your hearing and equipment . You just have to pay attention to not let the microphones route into your monitors through other routes such as GarageBand.

Focusrite has fixed the OS X installer for their software mixer (current version 1.8 - their answer to the ticket concerning the installer implied that my ticket prompted them to fix it for which I give them good grades; nothing much else in the OS X package seems to have changed otherwise) so after installation also non-administrator users can use the application but their answer concerning buffer sizes and latency was not very exhaustive
That seems to boil down to timing it for an answer but I have just returned from vacation - it might be a while until I get everything rigged to doing that. Their answer seems to imply that the CoreAudio buffer structure reacts independently to their driver, so their settings only represent ranges that CoreAudio software can then pick from. Can anyone direct me to technical documentation about CoreAudio...?

In the meantime I have tested the interface with a MacMini on FW800 and it works fine using a FW800-FW400 cable. The MIDI also works (as was to be expected) and S/PDIF in and out play along fine - that might actually be an option to hook up S/PDIF devices like secondary computers (you don't need to use that on the FW host computer since there are plenty of looping options available either in hardware in the PRO40 or in software - I especially recommend taking a look at JackOSX, which lets you route audio from any application to any application in a software patchbay).
Running my MIDI through the PRO40 instead of through USB for me solves one potential ground-loop issue and has the added benefit of reducing the number of connections between computer and studio to 1 FireWire.

Other experience:
Generally the PRO40 seems to be very stable on the input chain, but the outputs occasionally have issues with the clock signal IF the computer ever went to sleep with the interface attached (that was reproducible).
So for your session you are best off hooking everything up cold, then boot your computer (Mac in my case) and disable all power-saving states for the duration of your session. That way I have never had a glitch. In all cases where I had issues, only the outputs were affected (inputs kept working fine) and setting the clock to something else and then back would fix it. Only GarageBand has had this happen, I was unable to provoke it with Ardour/JACK (which offer direct control over the clock as opposed to GarageBand) - very possible that the issue is specific to GB. YMMV

If you have specific questions please let me know and I will try to answer them - within the limits of my possibilities of course.

Greetings from Canada and a happy new year, Otto
