I already compared it's phones output with the phones output of a RME HDSPe AIO. A while ago I had bad luck, there was too loud computer noise audible by the apart from this good phones output, but at the moment there's no computer noise anymore. One reason for me to switch to USB, is to separate the audio interface from the computer. However, the sound quality of the AIO's phones output is better, than the phones output of the PreSonus. Strange, since old home recording gear and old HiFi equipment provide usable phones outputs, but nowadays phones outputs of home recording equipment seem to be unusable. My Behringer mixer's phones output is disgusting, too, but the other IOs of the mixer are ok, maybe it's the same for the PreSonus. Actually I want ADAT IOs and a usable head phones output. I don't care much about the other IOs, so this already could be the showstopper for me. USB is tricky. First the PreSonus didn't work with Linux and also not with Windows XP, then I found an USB port that at least allows to use the PreSonus with XP, an OS just installed for tests. I hope I understand how to use alsamixer with this card, a brief test wasn't promising. To be continued... Regards, Ralf

Jack Audio Appliance?

by Schatzman, James

Is there a Jack Audio Appliance commercially available? If not, I would like to build one. Here are my requirements 1) Accepts 4 or more input audio streams at Xonar 7 rates (24-bit channels at 192KHz). 2) Makes the audio streams available to Jack clients on the network. 3) Is compact and reliable. What would be a reasonable compact platform to host such a device (processor speed/cores, memory, etc.)? Also, is it feasible to jack up the data rates even higher - say to several megasamples per second? Thank you- James

Yoshimi for your Christmas stocking

by Will Godfrey

V 1.5.0 - The Robin Still learning new songs and singing sweetly in the middle of winter. Vector control now has its own dedicated button on the main window. A little bit of shuffling meant that space could be created for it while actually making the window look neater, and the master controls more obvious! As a further protection against rogue sequencers making assumptions, any attempt to set an invalid bank root will be ignored. The same was already true for banks themselves. Also, on first time startup, discovered roots will be given ID numbers starting from 5 and in steps of 5. This makes it a little easier to re-arrange them to your preference. We recommend that you don't have zero for either, as this is the usual assumed number. If working from the command line, listing roots and banks will identify the current ones with a '*'. Also, we forgot to mention at the last release that listing instruments, as well as showing the current bank and root you are listing from, will suffix each entry with A,S,P depending on the combination of AddSynth, SubSynth, Padsynth. Channel switching has now matured to a 'Solo' feature accessed from the mixer panel. When described to a sound engineer his response was "Of course it's a Solo. A bit unusual, but where else would you put it?" Another new feature is one that has been asked for several times - a crossfade for overlapping note ranges in instrument kits. Filter tracking could never quite reach 100% so if using it to get 'notes' from noise it would go slightly out of tune. Well, now we have an extra check box that changes its range so that instead of -100% : 98.4% it will track 0% : 198.4% These new features are the first we've introduced that actually change instrument files. However, they are backwards compatible in that older versions of Yoshimi simply ignore them. Many of the controls now have active tooltips that show the current value when you hover over them, so you no longer have to click the control to see its value (and probably change it at the same time). Also, many have real-world terms. dB, Hz, mS etc. The biggie is MIDI learn. Yes it's finally here, and very full featured. It can be reached from the 'Yoshimi' drop-down menu, and tooltips will remind you of how it is used. There is a screenshot on our sourceforge page. More details on all of these can be found in the 'doc' directory. Under the hood: We've made a small, but useful improvement in note-on behaviour and a more significant one is in the planning stages. Note-on is when the greatest load is put on the processor. To build yoshimi fetch the tarball from either: http://sourceforge.net/projects/yoshimi Or: https://github.com/Yoshimi/yoshimi Our user list archive is at: https://www.freelists.org/archive/yoshimi -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

Brickeffects

by Gerald Mwangi

Hi guys, galls. A friend of mine has a start-up called brickeffects. This is a service where you can up upload a CAD model of anything (toy cars, penguins, mickey mouse etc). What you get is the prescription how build the model out of Lego bricks. And you get the bricks themselves by mail delivery!! This may seem off-topic, but I thought since many of you might be makers this interests you. Their campaign is at https://www.kickstarter.com/projects/1124674706/brickeffects-create-your-in… Have fun building, Gerald/ JimsonDrift

Music Made with Linux: Rated Blue-Turnabout Album

by info＠bandshed.net

Hi fellow LAU's! This is a kind of a small pre-release announcement of our new Album "Turnabout", in the next week it will be available in retail outlets and announced elsewhere but it's already on Soundcloud so I thought I'd post it here on LAU... This was recorded and produced on Ardour 5 and utilizes a variety of FLOSS and Commercial plugins including Ardour Team, Harrison Consoles, linuxDSP/OverToneDSP, Guitarix, Calf, U-he + SWH, CAPS, TAP, Furse Ladspa's. We also did a lot of work with mic placements and ambient stairwell miking as well as simple line-delays for natural reverbs. *ALBUM NOTES* "Turnabout" is our second Rated Blue album release following 2015's "Three Walls Down". Where "Three Walls Down" was initially a collection of songs for posterity "Turnabout" is a more cohesive collection influenced and written against the backdrop of the 2016 US Presidential Election (no we're not American but when the neighbor's house is on fire you pay attention!!). Our core musical inspiration remains the gut-level immediacy of the Blues within the collaborative interactivity of a guitar trio but stylistically and sonically Turnabout roams much farther afield than it's predecessor and is probably best summed up as 'Alt-Blues'. Turnabout opens with "Straight Up" a funky inspired plea for the media to cut to the chase. "The Second Sister" touches on gender and sexual equality. "When You Got a Name" leans heavily toward Prog and examines lives left behind by the cult of celebrity . The latin influenced title track "Turnabout" traces the insidious rise of Reality TV and it's troubling consequences. "Unsteady" surf-rocks out and rips on the unreliable nature of mavericks and "You" questions a seeming lack of world leadership. "Man On a Wire" closes the album with a collection of vignettes ending on an unresolved chord. If you are a Blues or Rock fan becoming weary of well-worn Blues cliches and tiring of flashy virtuosity we invite you to give this new release a listen and hope you'll find our 'songs-first' mentality an appealing alternative within the Blues/Roots genre. Thanks for reading (and listening). Glen, Connor and Pete - Rated Blue *ALBUM Link: https://soundcloud.com/rated-blue/sets/turnabout

AMEN $ Mother Function

by Neil C Smith

Hi, Just wanted to share something I've been fiddling with this week. AMEN $ Mother Function https://youtu.be/qTQoE5UHgP8 One sample, one function. Live coded single function demolition of the most ubiquitous sample in modern music. Takes a little while to get going .. working on that .. amazing what sounds you can get from one sample and a little maths! :-) This was created in Praxis LIVE, which was recently presented at the International Conference on Live Coding. I had this idea while I was there. It utilises a few useful things for live-coding per-sample functions that got added in v3. Best wishes, Neil -- Neil C Smith Artist & Technologist www.neilcsmith.net Praxis LIVE - hybrid visual IDE for creative coding - www.praxislive.org

[Speaking of (maybe) OT] : the Joué controller

by jonetsu

Hello, There's a new type of controller that's in the works. My impression is that it seems fun and expressive. It would even be more fun (or any fun at all...) if eventually 1) it succeeds and 2) it becomes possible to use it in Linux. It is basically made of swappable silicon modules with embedded electronics. It looks like a toy and IMHO that's the advantage. As it looks like a toy, the name Joué ('played') refers to both this aspect and the musical playing. Yes, they have a kickstarter page and they got some 58,000€ so far. The project presentation video: https://www.youtube.com/watch?v=mCdUoWXL5zc Cheers.

RME Multiface with cardbus interface & cardbus-ExpressCard adapter

by Iain Mott

Hi list, I'm trying to find a way to use an RME Multiface mark I with an old RME cardbus interface. My laptop doesn't have a cardbus slot but has an ExpressCard slot. I've read old threads of people successfully using the cardbus interface with a cardbus-ExpressCard adapter on Windows. Has anyone done this on Linux? From what I read, what's needed is a an adapter that requires no drivers. Thanks, Iain -- _________ Iain Mott http://escuta.org
