Fireface UFX working good with Sonar X3?

I've seen another thread about some of the FF UFX users having performance issues with X3.
I'd like to hear  if this is just a problem for a few, or is the FF UFX working good for most of the users.
I'm very close to buy one of this interfaces because it seem to have everything i need.
Please let me know if it's working good for you or not.
 
 

Thanks neirbod. 
Yes the UFX looks like a fantastic unit. 
 
Anyone else?

I love the FF UFX. It is a rock solid unit outside the exposure with X3 that several people are having. Other than the pops and clicks in X3, I have no other real issue with it. Timing is good in X3 with zero sync issues on straight playback.

FTR - mine is USB.

I have a UCX.
Using my computer at 44.1 Sonar measured these latencies.
 
Firewire
69 samples input
126 samples output.
195 samples round trip
 
USB
76 input
93 output
169 round trip
 
I love my UCX and have no issues with it. I will say it gets hot, which has not been an issue for me, but is worth mentioning in case you are aiming for a tight rack space.

PCIe Syba TI chipset Firewire controller for $25 is the card I used for the brief period I used Firewire with my FF UCX.
 
See Newegg.com for good pricing.

I definitely use it as a live mixer. I have mixed 5 live gigs using it to date, so not tons of experience (could be more than 5 but at least 5).
 
I REALLY like it. I like the compressors and EQs so much I've started recording the sends to the mains using loopback on the ADAT channels. What I do in Sonar ends up being great practice for mixing bands live. I can even save all the EQ Settings for a particular band and pop them back up.
 
The reverbs are wonderful.
The echo is an addition to the Reverbs really. It can be used independently (only echo no reverb). What you can't do is send 5 tracks to reverb and 1 track to reverb AND echo. The FX bus has Reverb and Echo inserts. Everything sent to that bus gets the same pairing of those two.
 
Now Reverb and Compression/Expansion IS track by track.
 
I have done real time bounces within Sonar to apply the reverb from the UCX to a mix. I have not really used the compressors for real time bounces, but I do use them when mixing live. Keep in mind that for this purpose you can use the ADAT channels too. So you can Send 18 44.1 tracks through the EQs and Compressors in the UCX and bring them all back into Sonar for mixing. Not sure it's worth the effort, but think about it.
 

RME Help File
FX Send. Setting the level of the signal sent to the FX bus which feeds Echo and Reverb. The current setting is also visible with closed channel settings, because knob and small fader are always synchronized. To make this function as useful as possible FX Send is locked to the highest submix, thus imitating the Aux Post Fader function of a standard mixing desk. When moving the big fader both knob and small fader will move. This way the reverb signal will always have the same relation to the dry signal.

The UCX allows you to save mix Snapshots during the show.
 
So, in the sound check, you enable phantom power on some tracks... maybe Inst on line ins direct from amplifiers. Now, click Store and save it as submix 1.
 
Next, your start adding EQ and compression to your various tracks. Click Store and Submix 2.
 
Now, get a little daring with the EQ. oops. Click the submix 2 button to undo.
 
The band asks to hear themselves without FX to trouble shoot a problem. Hit submix 1.
 
Problem solved, turn FX back on. Hit submix 2.
 
Try out different reverbs (save to submix 3,4 and 5). These will be used for different songs so the reverb stays fresh and interesting. Between songs, change submix.
 
See? Really lots of possibilities.
 
At the end of the Show, save the workspace for the Venue and Band.
 
Next time you're at the club, pull it up and you have all your EQ work, track naming, compression/expander settings, Reverb Sends up in a second.
 
Workspaces for DigiCheck are saved separately, but equally useful. Workspace includes graphical positioning of the UI for multiple instances of the programs. So, when you set them all up side-by-side and save as a WS, they open back up just the same.
 

I'm running an RME UFX via USB and it's very solid - very happy with it.  No issues.

I am an ultra-power user and have no issues using this about 20 hours a day.

Why am I jealous? giggle.
 
I hope you love it.

And what about latency (in USB mode ?
Is it short enough, if you need it to be ?

I tend to mix at 2048 because of switching screensets. Switching screensets can cause drop-outs for me.
 
I'm able to record at 48 sample buffer, but tend to use 64 like Karhide.
 
Now, for me, anything below 256 I consider useable.
 
Also, on my laptop, I have to bring the buffer up some. 128 or 256.

Thanks you !
