It seems everyone is dropping support for 32 bit machines these days - including a number of Linux distros. It makes me wonder how long it will be before single core machines go the same way. Has anyone seen any hint of that yet? I think it was LAC 2008 where I first heard discussion on how to plan for multi-core kit - not that I was touching any code back then :) -- 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.

[LAU] Random Clicks and Pops with Steinberg UR-22 ?

by Niklas Reppel

Hi everybody, i recently dug out my Steinberg UR-22 interface after not using it for several months. During playback, i experience random clicks and pops (s.b. encountered a similar problem with OSX: https://www.steinberg.net/forums/viewtopic.php?f=157&t=92352) They don't seem to be on recordings or bounces, but make me crazy while working with it. At first i thought it was an unfaithful combination of programs, but it happens with simple mplayer playback as well, with or without JACK. I have to add that the clicks sound fairly "analog", not like a "one" sample. Anybody experienced something similar ? Can't remember this happened the last time i used it ...

[LAU] Can't get the stereo imaging from the speakers

by jonetsu

Hello, I got speaker stands from the Yamaha HS5 powered speakers. So they are at ear level on each side of the desk. This results in hearing the music not as it comes from the speakers, but directly from the center of the monitor. Which is nice. One would think the audio comes from the monitor. To this the HS8 subwoofer sits on the ground under the desk to the left. To the left is also some 12x12 audio foam tacked to the wall, for guitar recording. The problem with this is that when a track is panned completely to one side only its volume decreases. The audio of that track does not move to the side. I have to use the headphones many times in the mixing to get the stereo imaging. Which is OK, as I like to get the headphones point of hearing, but it'd be nice to hear the stereo effect through the speakers also. Any advice on how to use speakers so that it's possible to hear the stereo imaging ? Cheers.

[LAU] USB audio interfaces with more than 16 digital output channels ?

by Niklas Reppel

Hi, i'm currently looking for interfaces that have more than 16 digital outputs for higher-order ambisonics applications. One of my requirements would be that they work with recent laptops, that is laptops that don't have expresscard or firewire interfaces, as those unfortunately aren't built any more. I've stumbled over a LAU post from 2016 where options were discussed. There's the DiGiCo UB Madi that is reported to work, but the price is ridiculous, and also it seems rare/hard to be obtained or even out of production. The RME Madiface USB aren't working at all (tried one of them myself). So, the PCIe and ExpressCard versions of the RME MADI interfaces have been reported working, but has anybody ever tried to use them with USB-to-PCIe or USB-to-ExpressCard adapters? Otherwise, ase the market brought forth new options ? Any advice is appreciated ! Best, Niklas -- Niklas Reppel www.parkellipsen.de

[LAU] [Music] jam230

by jonetsu

Just quickly, for fun. The context is a certain amount of people for whom Repro-5 and 1 are not working on their Linux systems while on mine they do. So I described my system and all that, and we exchange with Alex from u-he who works on the Linux versions of the synths, and then thought of posting some 'waiting room music' while a solution is searched for. So this is improvisation # 230. The synths are Repro-5 * 3, Zebra (strings), ACE (for the bass), pianoteq 6 for the, ahem, piano, and Biotek for the little buzzy critter. https://soundcloud.com/nominal6/jam230 Cheers.

[LAU] focusrite-control running in wine

by Peter

Dear All, has someone managed to run successfully focusrite-control.exe inside wine? I'd really like to access the hardware mixer from Linux. I have no windows installed on my Laptop, so I can't test whether there is an issue with the usb ports. I installed focusrite-control-2.1.7.exe in all kind of different ways, using wine from kubuntu 17.10, and winehg-staging. All I managed is that the programm opens and reports "No Hardware connected", same for the ASIO control. I also tried the live version of io-live--2017.03--e22-k4.14-k4.14-rt1-amd64, with the same result. Opening winecfg I can switch to my Scarlett 18i20 and pushing the button for testing sound it works. I've also installed OpenMPT1.27.02 inside wine and it works nicely. There, I can even switch to 96kHz, which doesn't work on ALSA/JACK, so something is done inside wine, not just passing to the outside. Best regards, Peter

[LAU] [ANN] Vee One Suite 0.8.6 - The End of Autumn'17 release

by Rui Nuno Capela

Wholly greetings! The 'Vee One Suite' of so called 'old-school' software instruments, synthv1 [1] as a polyphonic subtractive synthesizer, samplv1 [2] a polyphonic sampler synthesizer, drumkv1 [3] as yet another drum-kit sampler and padthv1 [4] as a polyphonic additive synthesizer, are here released just in time for the merry season greetings. As before, all available in dual standard forms:<ul> - a pure stand-alone JACK client with JACK-session [5], NSM (Non Session management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. The almost common change-log for this end-of-season follows: - Sync option added to DCO wavetable oscillators, as for making either one to hard-sync (slave) with the other one (master) in each pair. (applies to synthv1 [1] only) - Micro-fade-in/out that were stapled at the loop start/end points respectively is now gone.(applies to samplv1 [2] only) - Set on a minimum attack time of 500usec as much to prevent audible clicking on low-pitched notes. Back in order of appearance: **synthv1 - an old-school polyphonic synthesizer [1] ** synthv1 0.8.6 (end-of-autumn'17) released! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.
