I've been looking for a new audio interface and asked for advice in this thread. The other day, while comparing a few candidate models (e.g. Tascam US-2x2-SC, Steinberg UR22mkII, Scarlett 2i4 G2), I noticed that they all lacked a feature that is very important to me. Roland's Quad-Capture, which I've been using but causes SONAR to be completely silent when the project gets too heavy, comes with a simple software program (see below) in which you can see, edit and save/load all parameters, including the input gain value. This feature is very convenient as you can imagine, so I was very surprised to learn that the competitor products did not have it (correct me if I'm mistaken). It's so important that I'm considering paying more than what I said in the other thread if the interface displays at least the input gain value (so that I can copy it into Excel etc. for future reference). Do you know any audio interface other than Roland interfaces that has this feature?
 

 

Hm, if the Quad-Capture has that, then it seems likely that its big brothers Octa-Capture and Studio-Capture might also.
 
But I would expect them all to share the same driver code, so moving up to one of them, you could still experience the same problems.
 
Are you sure your issues aren't system-specific?  I don't recall ever hearing another Quad Capture owner report the same issue you described (Sonar goes quiet with a heavy project).

From interfaces I have checked, Digital Gain control (Digital Trim (tm) in MOTU terminology) exists only in RME, MOTU and some Roland interfaces... Most Digital Mixers also have it.
 

Those 3 interfaces you mentioned are all entry level. A lot of the better interfaces come with GUI mixers. Even the 6i6. But really, If it's time for a new interface make the commitment to quality and get a RME or Motu. 

^^^^ Higher level Focusrite products have front-end software that can be saved to the hardware (MixControl) and other interfaces have similar, essentially a digital mixer.

From the documentation, Scarlett (all models) have no digital gain control. From pictures, Clarett also do not have it. Mix control (so digital DSP) yes, save/recall DSP settings also yes. But gain control?

The hardware knob has no linkage inside the mixer (there are only 2 of these for all inputs... the rest are digital only). The mixer can control each input on each mix separately (digital faders). There are actually multiple faders and busses internally, so "input gain" there is a fader. It gets as "complex" as the interface it is running.

I am not sure which models carry MixControl (some Scarletts did not), and is certainly not unique to Focusrite.

I am confused by the question. MixControl is the ASIO control panel for the unit, and a fader is gain control. Did I miss something?

I had a Roland Octa-Capture.  It had a lot of flexibility in the Control Program.  I now have an MOTU and the control program and options in it are extensive (so much that I needed some hands on instruction).

check out totalmix, with RME interfaces

RME and MOTU audio interfaces allow you to control the "input gain" via software.
Behringer digital mixers (also function as audio interfaces) also allow you to control input gain via software.
