I have a question for any people who make use of this. Recent work means that in the latest builds some deep access into the synth engines is now possible with the status of all context steps being echoed to the prompt line so you know where you are. However this can get very long, so I'm wondering if it would be better to have a status line followed by a normal "yoshimi>" prompt. As has already been pointed out, this would then tend to orphan the last command actioned from the prompt. Currently, using minimised commands from the top level: 's p add voi env fre on' reports: 'Part 1 Kit 1 Add Voice 1 Frequency Enable Env Value 1.000000' and gives a new prompt line: 'yoshimi Part 1 on, Addvoice on, freq Envel on>' Bear in mind that the report is what you did, and the prompt is where you are (although there is considerable overlap). If you now do: 's at t 80' the report is: 'Part 1 Kit 1 Add Voice 1 Amp Env A dt Value 80.000000' but the prompt line is still: 'yoshimi Part 1 on, Addvoice 1 on, amp Envel>' We need to tidy up the responses, and intend to shorten the report line to just the control changed and its new value, as the steps to reach it will be in the prompt. Or should they be? That's my question. Another consideration is that the prompt is specific to the CLI but reports might be directed to the GUI console! Also, as well as blind users, we have at least one sighted user who runs graphically but sends commands via the CLI wherever possible. Finally, I'm sending this to both LAU and Yoshimi's own list as this is getting into unfamiliar territory and I would like to get the widest possible user views. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

[LAU] performance problems after kernel/microcode update ?

by Niklas Reppel

Hi, i recently updated my Arch linux system, to to the following version: Linux 4.18.6-arch1-1-ARCH #1 SMP PREEMPT Afterwards, i noticed that something has changed regarding the realtime permissions and that i had to install a new package called 'realtime-priviliges', which i never needed before, and subsequently add my main user to the 'realtime' group. In that wake, i updated the processor microcode, which i didn't use at all before (there always was some error message during bootup, but nothing else). After being able to start JACK in realtime again, i felt that there was a significant loss of performance. Things that didn't cause any dropouts before now start to crackle and gristle (as a sidenote, i mostly use SuperCollider to make sound). Also, and this puzzled me especially, there were dropouts, but no XRuns ... normally, when i push the system to the limits, i get XRuns, that'd be expected. But now, it's dropouts without, and they start way earlier. My machine has an Intel(R) Core(TM) i7-4600U CPU @ 2.10GHz Processor if that info is of user for anyone ... Anybody else noticed something like that recently ? Best, nik -- Niklas Reppel www.parkellipsen.de

[LAU] Recommended USB Audio Interface

by Mailing JS

Hi, what would, in your opinion, be a recommended USB Audio Interface for multitrack studio recording? In the past, I was happy with M-Audio Delta 10/10. It was using a PCI-Extention Card. Now, I'm searching for a replacement using USB. It could have fewer IO-Ports and I need no Effects-Processing on the card. Important is, if possible, out of the box connecting via jackd and channel adjusting via alsa mixer. Thanx for hints, Joerg -- --------------------------

[LAU] Dexed stuck notes

by Mark Raynsford

Hello! I've been using Dexed for about 18 months now, and a couple of versions ago, it suddenly started behaving badly. Essentially, notes get "stuck" on (as if they've not received a NOTE-OFF event), and even sending ALL-NOTES-OFF events doesn't unstick them. The only way to unstick them is to toggle the MONO switch on and off in the sequence (apparently this sends an ALL-SOUNDS-OFF event internally). I've filed a report here: https://github.com/asb2m10/dexed/issues/152 .. But it's kind of awkward to reproduce. I've only been able to get it to happen after I've gotten part way through writing a piece. I don't have this problem with any other instrument, so it does appear to be Dexed-specific. Is anyone else able to reproduce this problem? The easiest way would appear to be to grab the something.zip file attached to the bottom of the ticket and run it in Rosegarden. This assumes that you have Carla and Dexed installed (as a VST plugin). Failing that... Is anyone else this having problem with Dexed at all? I see it in all the major sequencers, and sometimes just when playing with a MIDI keyboard. -- Mark Raynsford | http://www.io7m.com

[LAU] retire_capture_urb: xxxx callbacks suppressed

by Kai Hendry

Hi there, On my T480s on Archlinux I often have issues with my USB microphone (h1 handy recorder): Sep 14 19:00:57 t480s kernel: retire_capture_urb: 2477 callbacks suppressed Sep 14 19:01:02 t480s kernel: retire_capture_urb: 2480 callbacks suppressed Sep 14 19:01:07 t480s kernel: retire_capture_urb: 2479 callbacks suppressed Resulting in just noise / garbage when recording with an ffmpeg/pulseaudio based script: https://github.com/kaihendry/recordmydesktop2.0/blob/master/x11capture https://s.natalian.org/2018-09-14/noise.mp4 It's difficult to reproduce, but I have managed to experience the issue again and again on stable kernels, e.g. Linux t480s 4.18.6-arch1-1-ARCH #1 SMP PREEMPT Wed Sep 5 11:54:09 UTC 2018 x86_64 GNU/Linux But not (yet) upon linux-lts 4.14.69-1 aka "LTS". Any tips how I should proceed here? https://www.kernel.org/doc/linux/REPORTING-BUGS is a bit overwhelming. Many thanks,

[LAU] Berlin Linux Audio meeting @ c-base 2018-09-11

by Daniel Swärd

Hi all. Next meeting at c-base is on Tuesday 2018-09-11. I'll be in the mainhall (or depending on weather) outside from 20:30 as usual. At the last meeting we were discussing if we should do something at the next meeting instead of just talking, and there were some suggestions: - Start defining a standard for communicating midi messages via OSC. - Test out some fun audio projects in the soundlab and/or do some jamming with Linux Audio projects· If we're going to go down to the soundlab, I'd suggest that we collect people in the mainhall/outside between 20:30 and 21:00 before going downstairs. What do you say? If going down to the soundlab, I'll reserve it for us. Cheers /Daniel

Because publicity is the true gospel of the modern times, the true gospel of our society of mass consumption. Even in Cuba, ordinary peoples don't give a penny for both the Marxism or the Capitalism, but they do want to be like us, part of the mass consumption, and that even if it is a madness of the extreme kind that kill the planet at an exponentially industrial rate. Like in the publicity, almost every body want more. And more, and more. And whoa! with internet, the pub is in HD, but it will never show you the enslaved children in the bottom of the mines (it is more slaves on Earth today than ever in History, and their number is growing fast), or the global and systematic destruction of Nature to make these mines, roads, plants, houses, infrastructures of all kinds, nor that this industrial mass consumption society is the best way to make Nature to return at it's mineral state. After us, the new intelligent specie will be robots, a mineral intelligence that will reign onto a mineral world where even the cyborgs will be extermninated. bip bip! > _______________________________________________ > Linux-audio-user mailing list > Linux-audio-user(a)lists.linuxaudio.org > https://lists.linuxaudio.org/listinfo/linux-audio-user -- If you have a problem and you are not doing anything to fix it, you are at the heart of the problem.
