Great update of the Saffire Pro 40, though I find the previous software version (Mix control) was a little bit more intuitive
Martín Perrone
Like it. The box was a little broken
Tim Stelzer
Very versatile interface. The number and variety of inputs and outputs opens up a lot of possibilities in my small home studio. Very good sound quality, especially when considering the price of the product. Also, it comes with a ton of useful plugins.

Some little scratch on the sound card, but everything work perfectly. It's used but not abused ^^ About the headphone out quality: I ear a difference between my Arturia audio fuse and this one. It's sounds like stéréo space is less big, more enclosed. I will use another sound card for mix and premastering when I'll use headphones during those process. Quality: 4 stars because of headphone out quality, Value for money: 6 Stars :-)

I upgraded from the Saffire Pro 40 for use with newer computers. So far it's been great and the USB interface is working very well. The new software was a little bit confusing at first, but it was very easy and customizable once I got used to it.
Easy to use and good value for money.
James Dellorefice
The sound is solid. The unit is intuitive to use. Great support from the company.
My 18i20 didn't work out of the box--it did cause a link to pop up on my computer, so it was being recognized, but the Focusrite software wouldn't recognize the device. I contacted Focusrite tech support and after trying a couple things they said to send it back and they would send a new one. That sounded like a potential waste of time to me--I had a hunch it was a software problem, not the hardware. I have a new M1 Macbook. So I plugged it into an old computer and it worked. After it updated its firmware, it then worked on my new Macbook. Glad I didn't trust their tech support and have them ship another brick. The only reason I bought the 18i20 is because Focusrite obsoleted my (perfectly functional) Saffire Pro40. So suffice it to say that I don't trust Focusrite to properly support their products and I recommend you buy from a different company.

This is a nice update from my previous Focusrite Saffire Pro 40 which served me well for over a decade

Focusrite deliver again. An excellent audio interface; sturdy construction, very nice pre-amps, and enough inputs to cover my needs for casual jams with friends. The control/mix software takes a little getting your head around, but works as advertised (and actually, not that hard to understand). The quality of sound is fantastic, and for the price (I took advantage of the trade in offer), is impossible to beat. Set up was a breeze too, and Focusrite's support is excellent when you need it. 5 stars all round. I'm super happy with this purchase. Incidentally, I traded-in a Saffire Pro40 and the 18i20 is better in every way.
Bruce Mawer
This is exactly what I was looking for. Highly recommend by thousands of other users. I am not disappointed.
Andy C
Great interface! Shame phantom power isn't per channel, rather than banks of 4, but i can live with that. The sound quality is decent!
Max Hodges
Sounds great , seems stable and is exceptional value , a worthy successor to my Saffire
Marco Naranjo Morelos
Excellent purchase
Best regards to all focusrite team for the Perfect transition
Peter Nelson
Focusrite is top-notch in my book. I had a 1st Gen interface from about 2012 and that wouldn't work well with my new M1 Mac Mini. The folks at Focusrite gave me a very fair trade-in deal so I could get the 3rd Gen. To me, that says that they appreciate and value their customers and are willing to do meaningful acts to retain a customer. On top of that, the interface is working out really well in my recently remodeled music room/studio. I will definitely look to Focurite/Novation for products in the future. They have earned my respect and trust. Let's make some music!
The product is great. I had the Focusrite Pro 40 and it had developed issues on a couple of channels. The natural alternative in 2021 was the Scarlett 18i20. I was concerned about it being USB2 versus the Firewire 400 connection in terms of bandwidth. However, I wasn't disappointed. I ran a 24 track virtual instrument (plus audio) session on Logic Pro X, 2012 Mac Mini (16Gb, OS Mojave) and had no issues. One thing I was a bit worried about was that I went into the Focusrite Control software at one stage and it couldn't see the Scarlett. A reboot sorted this out but given that the Air setting is controlled by this, I hope this glitch is addressed for users of MacOS Mojave. Most of us are using this because of some legacy hardware drivers being 32 bit, which Catalina and above doesn't tolerate. Overall, this is a great product. Many thanks to Focusrite and the Tech support team, particularly Andy.

Firstly, Focusrite helped me out in a pinch by offering me a very attractive option to replace my older firewire Saffire units. Secondly, the units themselves are gorgeous: Ergonomically friendly, easy set up, a much better & easier control app, & they sound wonderful. Very fast via USB-C & with undetectable latency as far as these ears can discern! The price point is killer! But I'm rambling...I can't sing this company's praises loudly enough! Bravo, people!! Well done & Cheers!!
Bryce Kim
Quick and easy to use! Like the Solo, just bigger.
Its an excellent pre-amp, and a great replacement for my Saffire liquid 56 interface.
James Matthews
Easy set up procedure. Great sound. Mix software a huge improvement from the old Mix Control.
Jill Jarman
Got tbis to replace an older Focusrite interface. Clean sound, works with my DAW (Cakewalk for bandlab) and notation programs (Finale) flawlessly so far. The DAW instantly recognised the interface. Very easy to set up with on screen walkthrough instructions. Moving from Firewire to USB was worried about latency but testing with a software piano there is no difference. Yet to try with full midi / software orchestral set up. Have used the midi also so altogether impressive bit of kit.
Mark Kono
Good value and flexible interface.
Max Padovani
I just recieved it, and will be using it for recording next week. Everything seems to work.
Sidney Joseph
Really awesome interface, excellent preamps and easy to setup and use
Ben Garnett
Just a really solid model, at the perfect price/performance ratio for an enthusiastic amateur such as myself. Pre-amps are fine, converters are great, and driver performance is rock-solid on my Windows 10 system.
keith watkins
it took longer to rack it than to set it up. Excellent product that sounds great.
Wolfgang Schrepfer
I buy this Hardware from focusrite. I will integrate the hardware in my Studiosystem at home.
Santiago Urrusti
Nice sounding, excellent condition
Michael Boyes
For the money great pre amps and some lovely touches that makes this unit a joy in the studio
Nicolas Bertrand
No electric converter
Great interface. I have had one in the past and had no troubles, clear audio and a great looking bit of kit for a rackmount. The 3rd gen sometimes doesn't like USB 3.0 on a Windows PC so watch out for that.
Guy Walker
I own a 2nd gen Scarlett 18i20 and the 3 gen in hooking up and being up and running in under 30 minutes seems to be an awesome upgrade from the 2nd gen which was very good to begin with. The extra Adat in/out is a plus.
James Hoover
Excellent product and support!!!
Have only used it for a few days but so far it works well. The Control software is no the most intuitive thing on the planet, a bit buggy and often drops out and shows that the unit is not connected when it clearly is and functioning. Focusrite could improve on that.
SABAG Ivy Gamboa
For the price,it s amazing soundcard.
Albin Johansson
I really like it, especially since it's fully compatible with FL studio.
Ben Noble-Chirstoff
Very good value for money. Very good design and quality.
Best bang for the buck! I love Focusrite!
Fuzzy Disco
Great product, should be just what we needed.
