/dev/cpu_dma_latency or setting '*.max_cstate=0 idle=poll' and power management

by Jeremy Jongepier

Hello, How does opening /dev/cpu_dma_latency and disabling CPU sleep states or disabling CPU sleep states with kernel parameters relate to CPU frequency scaling? Does disabling sleep states also disable frequency scaling? Asking this because I'm attempting to rewrite the system_configuration wiki page. Thanks in advance! Best, Jeremy

[music] squeeze it in

by Atte Jensen

Hi Lurking more than posting, hope it's ok to share a track, I posted on my youtube channel yesterday... As some of you may know, I'm all into modular now, but use linux native reaper for recording performances in one pass, and subsequently mix everything. These last couple of months, I went ahead and also started editing the video in reaper, which is streamlining the process a lot. I generally suck at video stuff, so unfortunately I have to rely on kdenlive for color corrections and de-noising videos, which obviously adds an annoying extra step. I hope reaper will grow its video editing in the future, and be able to keep everything in one piece of software. The track is jazz-of-some-sorts, sequenced from the modular, with a few hardware synths thrown in for polyphony and other things impractical in a modular environment. Oh, and a keyboard solo on the blofeld (quite recent acquisition, absolutely love this synth). Anyways, hope you enjoy it: https://youtu.be/mJTssnleHUA Cheers -- Atte http://latestyoutube.a773.dk

[music] Dancing on 3rd street

by Jeanette C.

Hey hey, a new track, something upbeat and "empowering" for spring: https://youtu.be/GcYAcvUBaSM OGG version: https://www.dropbox.com/s/tzjupql023diuc7/dancing_on_3rd_street.ogg Loads of Yoshimi for the main FM-pluck/marimba and layering, Csound for vocal processing/alienating and risers. LinuxSampler for firing of those riser/fx and xylophone. More hardware for the rest and tons of LADSPA plugins for processing. I can only applaud the power in those plugins, especially for seeing what they did to the vocals. The first two or three vocal lines are more miss than hit, but it gets a lot better after that. Feedback is welcome. Beyond that: just enjoy! Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c And I love the way with just one whisper You tell me everything <3 (Britney Spears)

CollisionDrive v0.1 released

by Hermann Meyer

CollisionDrive is modeled after the Horizon Devices Precision Drive(*), a modern overdrive pedal with a built-in noise gate. Besides the usual Volume and Drive controls, the CollisionDrive features Attack and Bright controls. The Attack control manipulates the response of the pedal, turning it down simultaneously softens the overdrive attack and increases the sustain. The Bright control gives you even more flexibility. It can add presence to darker sounding amps, or remove buzzing when needed. The Gate control sets the noise gate threshold. In the plugin interface, this control lights up to indicate that the noise gate is active. (*) 'Other product names modeled in this software are trademarks of their respective companies that do not endorse and are not associated or affiliated with this software. Horizon Devices Precision Drive is a trademark or trade name of another manufacturer and was used merely to identify the product whose sound was reviewed in the creation of this product.

Updates of zita-audiotools and zita-jacktools

by Fons Adriaensen

Hello all, zita-audiotools-1.3.0 and zita-jacktools-1.6.0 are now available at <http://kokkinizita.linuxaudio.org/linuxaudio/downloads/index.html>. If you have previous versions, installing these updates will require some extra work. This is for two reasons: * The python package names have changed: audiotools -> zita_audiotools jacktools -> zita_jacktools * The setup.py files now use setuptools instead of the deprecated distutils, and will install a python 'egg' directory. This requires the following actions: * Before installation, remove all traces of any previous versions from your python site-packages directory. Then just make; sudo make install; sudo make clean. * In existing applications, the import statements must be modified to refer to the new package names. Thanks to Marc Lavallée for both suggesting the name change and testing the new releases. Ciao, -- FA

[OT] Missing some LAU emails (initial messages)

by Lorenzo Sutton

Not sure if this is something only on my end, but I seem to have missed some recent 'initial' message threads from LAU such as "New Software: Tembro, All-in-one instrument (Sampler or Rompler)" [0], "[music] Pick me up" [1], "Lost soundfont" [2] Interestingly I did then correctly receive thread responses to these. I did check my spam and no trace in there (and LAU is in theory whitelisted since a while). I'm wondering if this might be some setting on my side (including ML settings, although I didn't change anything recently), some gmail quirk? I use Thunderbird as a client but I don't think that is relevant (or is it)? Any tip or help appreciated :-) Thanks!

I tried adding a ctl stanza: ctl.!default { type hw card 0 device 7 } This doesn't affect aplay, but firefox doesn't output to headphones or HDMI with this setting in asoundrc. I welcome any suggestions to get firefox to default to the asoundrc setting. TIA, Joel -- Joel Roth

Lost soundfont

by Will Godfrey

I'm trying to recover an old project, and it uses a specific soundfont P51f.sf2 (not PC51f.sf2). I've somehow lost the copy of this I once had and can't seem to find it online. Any help most gratefully received. -- Will J Godfrey https://willgodfrey.bandcamp.com/ http://yoshimi.github.io Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.
