Re: [Rosegarden-user] Focusrite Scarlett 2i2 USB audio interface
For what it's worth, I've been using a Komplete Audio KA6 for some time with no problems at all. It is USB2 class compliant and 'just works' (tm) It has 6 channels in and 6 out, one pair being SPDIF. Also 2 of the inputs are combined XLR/jack Mic/Instrument ones. All the analog I/O is balanced. Finally there is a switchable headphone monitor. -- W J G -- Monitor Your Dynamic Infrastructure at Any Scale With Datadog!

I plugged it in, and it worked. It's absolutely reliable. I use it via jackd all the time, even when listening to music or watching videos. I configured pulseaudio to use jacks, so everything works. The 2i2 runs for hours and hours without making trouble (like my old M-Audio Fast Track Pro which started cyloning). But the 2i2 doesn't have a mixer. No problem, I hear you say, we have jack_mixer. Yes, we have, but how do we tell all the jack-clients to connect to the mixer's input instead of system:playback? Don't cry in despair, there is a solution: jack.plumbing If jack.plumbing is active and its ruleset is carefully crafted, then the magic can happen and jack.plumbing disconnects jack-clients from system:playback and connects them to jack_mixer. Take this ~/.jack_mixer -- snip -- -- snap -- And then take this ~/.jack.plumbing -- snip -- (connect"alsa-jack\..*jackP\..*:out_000" "jack_mixer:ALSA L") (connect"alsa-jack\..*jackP\..*:out_001" "jack_mixer:ALSA R") (disconnect "alsa-jack\..*jackP\..*:out_.*" "system:playback_.*") (connect"Clementine:out_jackaudiosink-.*_1" "jack_mixer:JACK L") (connect"Clementine:out_jackaudiosink-.*_2" "jack_mixer:JACK R") (disconnect "Clementine:out_jackaudiosink-.*" "system:playback_.*") (connect"Qtractor:Master/out_1" "jack_mixer:JACK L") (connect"Qtractor:Master/out_2" "jack_mixer:JACK R") (disconnect "Qtractor:Master/out_.*" "system:playback_.*") (connect"rosegarden:master out L" "jack_mixer:JACK L") (connect"rosegarden:master out R" "jack_mixer:JACK R") (disconnect "rosegarden:master out .*" "system:playback_.*") (connect"MPlayer.*:out_0" "jack_mixer:ALSA L") (connect"MPlayer.*:out_1" "jack_mixer:ALSA R") (disconnect "MPlayer.*:out_.*" "system:playback_.*") (connect"PortAudio:out_.*[02468]" "jack_mixer:JACK L") (connect"PortAudio:out_.*[13579]" "jack_mixer:JACK R") (disconnect "PortAudio:out_.*" "system:playback_.*") (connect"PulseAudio.*:front-left" "jack_mixer:PULSE L") (connect"PulseAudio.*:front-right" "jack_mixer:PULSE R") (disconnect "PulseAudio.*:front-.*" "system:playback_.*") (connect "jack_mixer:MAIN L" "system:playback_1") (connect "jack_mixer:MAIN R" "system:playback_2") -- snap -- Start jack_mixer, start jack.plumbing and let the magic work :) The next time uncle Holger will tell you how you can move and resize windows automagically (even to workspaces) with gdevilspie and devilspie :) Regards Holger -- Monitor Your Dynamic Infrastructure at Any Scale With Datadog!

Re: [Rosegarden-user] Focusrite Scarlett 2i2 USB audio interface
My 1010LT just died (at least the MIDI part did). Right now I'm largely recording on my Zoom R24 and importing - I actually kinda prefer the appliance for tracking guitar/bass/vocals - but I've got my eye on a multitrack audio interface.I'd been eyeing the Focusrite firewire interfaces - although now that I'm recording drums via MIDI instead of audio - in all honestly I can live with a 2ch interface.

[Rosegarden-user] Focusrite Scarlett 2i2 USB audio interface
I forgot to spec a PCI port on my latest motherboard, so I have been without my Audiophile 24/96 for months. I will be composing some music for my new software company in the next while, so I finally had to go hunt down a solution to this problem. I came up with the Focusrite Scarlett 2i2 after spending a few hours researching my options. It was reported working as far back as 2012, and nothing since then gave me pause. I like their attitude toward Linux, which seems to be, in a nutshell, "We don't support Linux, but if anybody is writing a driver for Linux, here are some technical details for you." http://us.focusrite.com/usb-audio-interfaces/scarlett-2i2 I haven't done any real work with the interface yet, but my first impressions are really positive. I plugged it in, and it worked. Specifically, here's how I rigged it up: onboard audio -> Behringer Eurorack UB1002 mixer -> 2i2 -> external amp I left pulseaudio running on the ac97 on my motherboard and configured JACK to use "Scarlett 2i2 USB." I recorded a mixture of some Youtube video (pulseaudio -> ac97 -> Behringer mixer -> 2i2) with one of the Rosegarden sample files that uses DSSI synth plugins (rosegarden -> jackd -> 2i2) and everything worked. I have fiddling to do to optimize the setup and get the levels right and so forth, but this was highly encouraging. The audio quality is crisp, clean, and noise free. I would probably want one of the variants with more inputs if I didn't have the mixer, and some of those variants were NOT reported as working. The 2i2 was, and it does. USB audio interfaces appear to be a very evil thing in modern times. They used to work well in the USB 1.0 days, but most current offerings are USB 2.0, and most of those are not class compliant. I poked around for a few hours researching this that and the other before settling on the choice I did make. It appears to be one of a very limited number of available options, and this one is now tested and approved by yours truly. (Next up, a review of the Korg Triton Taktile 49. My old controller keyboard is so obscure googling it just shows all the places I've talked about it over the years. It's built like a tank, and should be repairable, but I just want something new after 20 years. It has a MIDI OUT, but input comes from USB only. I have no clue if I will be able to access the built-in sounds from Linux, and will report back once the keyboard arrives.) -- D.
