Steinberg CI1 - Intermittent Static Spikes (Yamaha USB chipset 0499:1501)

by progenitorvirus

Hi all, Wasn't entirely sure where to ask this question, but I'm hoping someone can help me with a small problem: I'm using the Steinberg CI1 Audio Interface running Ubuntu 13.10. As of a recent kernel, this Audio Interface is supported now (!). However, I'm noticing that during playback, I get intermittent bursts of static/white noise. Playback will be going fine, and the audio for less than a second turns to static (I can describe as sharp and loud white noise) then goes back to playing fine. This can happen a few times in succession, or go minutes without happening at all. Earlier last year when fighting this issue, I had authored a post on the Ubuntu forums here: http://ubuntuforums.org/showthread.php?t=2150401 Which, before the kernel had been updated to support the Steinberg CI1, did get it working but still with this static. I had thought it was a fluke in my little 'workaround', so decided to wait until it was officially supported in the kernel. I had gathered my information from a Clemens Ladisch (and credited!) a post on this very mailing list: http://linux-audio.4202.n7.nabble.com/Support-for-Steinberg-UR22-Yamaha-USB… At this point now, with official kernel support and the issue still happening, I'm at wits end here looking for a solution. Thanks for any and all help! -- View this message in context: http://linux-audio.4202.n7.nabble.com/Steinberg-CI1-Intermittent-Static-Spi… Sent from the linux-audio-dev mailing list archive at Nabble.com.

Proposal about support for multiple jack-dbus servers

by Zlobin Nikita

Hello. I looked to MPRIS specification in order to write jack transport client with this interface, and noticed solution, which could be used for jackdbus too. Currently jack serice name is fixed: org.jackaudio.service In MPRIS naming is like <prefix string>.<instance name> (e.g. org.mpris.MediaPlayer2.audacious). For jack it could have this form: org.jackaudio.<server name> or org.jackaudio.service.<server name>. Older name may be kept for compatibility, and most likely to be created by first jack server, appearing in user session. With such approach it could be possible for other daemons, e.g. ladish, to expose jack-like interfaces in more common way. Of course, currently it is done as essential (using of different service names), but it is not standard. With proposed approach it may be possible even to browse jack services. Control tools like qjackctl could even propose some menu (sidebar in patchage) or even (sic! =) transport control rack for better convenience.

[ANN] GUI toolkit and 2 audio applications, also for Android

by W.Boeke

Hi, This is an announcement for a GUI toolkit, which works for Android tablets as well as for the Linux desktop. This means that all widgets are touch-friendly, such that values can be observed also when you put your thick fingers on the sensitive areas. The library is accompanied with 2 audio applications: a (more or less) classic synthesizer and a (not so classic) organ. Both are polyphonic. My intention was to create applications that you can use at home with a regular MIDI controller, and outdoors with an on-screen keyboard or with a mini MIDI controller. Android is traditionally plaged with a long audio latency, but the latest version (KitKat) is really good in this respect. Also the USB interface is fast. IMHO, these musical instrument applications are really playable now. Notice that you can build (if you want so) an application for Linux only, or for Android only. The source code as well as an introduction can be found at: http://members.chello.nl/w.boeke/ct-gui/index.html Comments are welcome. Regards, Wouter Boeke

[ANN] CAPS 0.9.17

by Tim Goetze

CAPS 0.9.17 =========== http://quitte.de/dsp/caps.html The latest release of CAPS, a collection of LADSPA plugins, contains two important bugfixes and minor sonic improvements. http://quitte.de/dsp/caps.html#CHANGES James Morris insisted that something was wrong with the PlateX2 stereo reverb, and indeed, it turned out that its damping parameter would not be read correctly. (This bug, it pains me to admit it, probably dates back to 0.9.0, possibly even earlier. In my defense, I only ever use the mono-to-stereo version which was not affected.) Ricardo Crudo isolated a potential segmentation fault triggered by the 'model' parameter selection of the CabinetIV plugin. Thanks guys! http://quitte.de/dsp/caps.html#Download Upgrading is recommended. Enjoy, Tim

[ANN] XSL stylesheets for converting specimen banks to petri-foo banks

by Thomas Mayer

Hi, I have just finished two XSL stylesheets for converting specimen banks to the save format used by petri-foo, so a user can easily switch to petri-foo: https://github.com/residuum/specimen2petri-foo There are two stylesheets, depending on your locale settings, i.e. if your locale uses comma or dot as decimal separator (if 1/2 is saved as 0.5 or 0,5 on your system). If there are any other decimal separators out there your copy s2p_comma.xsl and replace strings "0," and "1," to your settings. Do not do that with s2p_dot.xsl, because necessary version information for XML and XSL use strings like "1.0" etc. Standard sample rate is set to 44.1 kHz, if you want to change to another value, just edit the value in line 6. If you encounter any bugs, open an issue on Github or send me an email. Thanks, Thomas -- "Spielen Sie Strip Schnipp-Schnapp?"

Re: [LAD] Call for testing: ALSA driver for Fireworks/BeBoB based devices

by Takashi Sakamoto

Hi Maximilian, Thanks for your test and report. I cannot reproduce the bug which you reported, with: - Debian GNU/Linux 8 (jessie) - Linux kernel 3.12-1-amd64 - mplayer2 2.0-701-gd4c5b7f-2 - All of BeBoB devices which I have - $ mplay -ao alsa:device=hw=1 /usr/share/sounds/alsa/* I believe 'verbose' option for mplayer may help our debugging.

Release of new WORLD-based voice synthesizer

by Tobias Platen

Hello WORLD is a free software speech synthesizer on the basis of a Vocoder. It has been widely used as a backend for UTAU[1] but it should be also possible to use it as a backend for eSpeak and other accessibility and/or music applications such as the "Singing Computer"[2]. My modified version of WORLD uses the well known vorbis codec for compression. The world4espeak synthesizer is interface compatible to MBROLA, and can be used to synthesize both singing and speech in real time on a modern computer. It is hosted at gitorious.org [3]. Currently there are no voices yet, a manual how to create voices will be published soon.

Converting specimen banks to petri-foo

by Thomas Mayer

Hi, I have played around with petri-foo the first time, and I am thinking about switching from specimen to it. Is there a utility to convert specimen banks to petri-foo banks? As far as I can tell, it is a simple XML transformation, and I would try that, if such a utility does not exist. Thanks, Thomas -- "Ich komme aus dem Staunen nicht heraus."
