Focusrite Scarlett 2i2
Hello,
Does anybody has this audio interface and could share his experiences with it? I'm interested in getting one and I would love to know if it is working out of the box with JACK. There were quite a fuss after the release concerning badly written drivers for Win7 and MacOS but it seems it was resolved. Anyway, any iput is appreciated.

Re: Focusrite Scarlett 2i2
Every interface that is supported by alsa or ffado works with jack.
According to this links it works.

Re: Focusrite Scarlett 2i2
Thanks for the response and links, the first one is new to me. Looks like the card is functioning pretty well.

Re: Focusrite Scarlett 2i2
I had always trouble with the m-audio Fast Track Pro: After some time the sound got noisy, sometimes there were cracks in recordings. Windows users report the same problem. And it was recognised only as 16 bit interface from a standard kernel.
Then I bought the Focusrite Scarlett 2i2. It's stable. It's recognised as a 32 bit interface. I like it very much.
I don't mind the lack of a MIDI-interface. I don't need it.

Re: Focusrite Scarlett 2i2
I have this unit; and it works FLAWLESSLY with my Ubuntu Studio setup. Didn't have to do any configuration or anything; pretty much plug and play. Usually record at 96k with 0 xruns and less than a milisecond of latency. HIGHLY recommend it.
Re: Focusrite Scarlett 2i2
Seems solid indeed! Thanks for info.

See this post:
http://www.linuxmusicians.com/viewtopic ... 495#p32773
And my response to that:
http://www.linuxmusicians.com/viewtopic ... 495#p37495
It shows how to "do the math" to compute the frames buffer, periods and sample rate together and predict the latency - and most important, use the correct numbers from the formula:
(frames/sample rate)*period = theoretical latency

Re: Focusrite Scarlett 2i2
Nice to see people have had success with 2i2!
I have been struggling with mine till frustration. Problem appears with buffer size under 512 (48kHz sample rate, number of buffers 2): Scarlett halo leds keep on flashing, sounds and looks like it resets itself over and over again. With 512 sample buffer size it works perfect, but the latency with guitarix monitoring while recording becomes unacceptable.
I tested it with two computers (laptop Core i5 M520 @2.40GHz, desktop Core2Duo Q6600). There is no USB hub between 2i2 and computer. I have tried normal, low latency and rt kernels, it makes no difference. Laptop uses Kubuntu, desktop fresh Ubuntu Studio with Pulse Audio disabled and used improvements suggested by QuickScan.pl.
Has anyone else ran into this problem with 2i2? Any suggestions how to proceed debugging this?
Also, a warning for prospective guitarist buyers: 2i2 input maximum input level in INST-mode is very low (-3dBu). I am unable to use any of my passive pickup equipped guitars for direct recording, as all my bridge humbuckers cause violent clipping. Sure, this was clearly stated by specification. I did not realize to check numbers out carefully, as I thought INST-mode was specifically designed for this purpose.

Re: Focusrite Scarlett 2i2
Same here. I don't find it _that_ annoyng in rakarrack though - your experience may vary.Problem appears with buffer size under 512 (48kHz sample rate, number of buffers 2
In case you're not already following (or you were not the original submitter) I am following these two kernel bugs filed against ubuntu for a resolution:
I get the same error for my Focusrite as in these bugs:
https://bugs.launchpad.net/ubuntu/+sour ... ug/1191603
https://bugs.launchpad.net/ubuntu/+sour ... ug/1185563
(Short story: it seems to have used to work in Linux 3.5, but it was not 100% USB compliant behavior.. so.. heh)
Re: Focusrite Scarlett 2i2
The Scarlett 2i2 has no MIDI inputs, but I need to know if it can be used to send and receive MIDI signals in qjackctl. Using A2JMIDID, would I be able to connect MIDI software to the 2i2's outputs in the MIDI section of qjackctl's Connections manager? This will determine whether I buy this interface or not. Please let me know if it works or not, if you know. Thank you!

Re: Focusrite Scarlett 2i2
MIDI is not an audio signal. The 2i2 deals only with audio (ie audio tracks and softsynth output).Smeefer wrote:Using A2JMIDID, would I be able to connect MIDI software to the 2i2's outputs in the MIDI section of qjackctl's Connections manager?
I suspect you're asking the wrong question about what you want to do. Do you own any gear with MIDI jacks?

Re: Focusrite Scarlett 2i2
No I do not own any MIDI gear that connects to MIDI hardware inputs. Can I use the 2i2 with A2JMIDID and Qsampler? If the answer is yes, then I'm stoked on giving it a try. I do not know whether or not having MIDI hardware jacks would make a difference.

Re: Focusrite Scarlett 2i2
Hi, new to Linux, left Windows...I just can't get Qjackctl to work with my Scarlett 2i2 2nd gen.
I'm new, so I'm sure I'm doing something wrong but I always get the D-BUS error.
I've got the Scarlett selected for input and output through the advanced tab.
When I click on connections, there is nothing, then it gives me the error. Any help would be greatly appreciated, loving Linux so far. Using Elementary OS.
