Dave Phillips' article on Linux audio plugins... is there a copy online somewhere?

by Nikhil Nair

Hi, I've found a few references to an article Dave Phillips wrote, entitled "Linux Audio Plug-Ins: A Look Into LADSPA". It's referenced on the front page of www.ladspa.org, and was, it seems, on O'Reilly's web page. However, the O'Reilly links seem to be broken, and a number of Google searches have turned up nothing. (The LADSPA homepage didn't actually list the title - I found that elsewhere; I'm assuming there is just one article that I'm seeing references to, but if Dave had more than one article on O'Reilly concerning LADSPA, this may further confuse the issue!) Can anyone direct me to a copy of this article? Failing that, is there an alternate source of introductory material you'd recommend? Thanks, Nikhil.

starting Bristol with scala

by tom haddington

Hello, All! I'm running UbuntuStudio 18.04 and am using this command to start bristol: startBristol -b3 -scala ji_12.scl I got bristol from the repos, which is completely up to date.. The scala file is in .bristol/memory/profiles. The problem is that I hear no difference in the chords. That's the just intonation that Robert Rich used for Geometry, and the A-flat and G-flat chords should be particularly spicy. I've pointed the command line to the specific file in my scala folder, but the output tells me that bristol can't load the file ji_12.scl.scl. I'm not sure why it adds the suffix. What am I missing? Also, if anyone knows of a Hammond emulator that is compatible with scala, I'd love to hear about it. That's the real goal. Bill

[OT] Future of Music Distribution (and examples?)

by Andrew A. Grathwohl

Hello Linux Audio folks! I wanted to see if I could get a conversation going about the future of music distribution. Given that we are people who make creative works with free software, I figured this is as decent a place as any to discuss what is out there, what is possible, and what should be avoided. My own personal approach to distribution is detailed below, but I invite others on this list to share their own methods and ideas. By now, most of us are probably resigned to the fact that the music world will look quite a bit different going forward, compared with prior eras. Many musicians feel that today's points of engagement with music fail to provide adequate revenues, and are taking to social media to criticize Spotify and the ilk for not being better "stewards" of music. I largely agree with those sentiments, which is why I have been taking the opportunity to construct a solid home base for my music project <https://multipli.city>, which is fully operated on my own physical hardware and some AWS cloud services at a cost of $7/month. It's just a simple jekyll template <https://github.com/SacredData/pRoJEct-NeGYa> hosted on GitHub Pages. However, by publishing my music releases to my own jekyll page one time, I get the added benefit of also publishing to all desired locations on the web simultaneously, including to a podcast feed <https://multipli.city/podcast.xml> compatible with Apple's podcast network. It's weird to me that we are still trying to unit-price music in a world where it's cheaper and easier than ever to record, produce, and distribute it. I am not necessarily interested in profiting from my own musical endeavors, but a friend of mine is a rather popular independent electronic artist, who has pointed out to me that despite millions of annual streams, streaming services alone don't provide him anywhere near a livable income. In my opinion, this shouldn't be so. There's also the issue of being beholden to the whims of private firms who run various online music services. Anyone here miss SoundCloud Groups, for example? I've begun to wonder if solutions like mine could be the foundation for a new kind of music distribution approach - perhaps one where musicians maintain podcast feeds, where monetization vectors are much more profitable and much more flexible for individuals to exercise without betraying their own values.

[Music] Garden realities (3d soundscape)

by Jeanette C.

Garden Realities is a 3D binaural soundscape or sonic world, based entirely on field recordings of summer birds, with rather subtle processing. https://youtu.be/FfMo_2ZO7_8 To get the full effect of this piece, you best listen to it on headphones and try to sit rather still. The piece was entirely realised in Csound, using the HRTF opcodes/modules for spatial placement and movement. Some field recordings, the chicken in particular, were contributed by my favourite Motzhuhn. :) I hope you get taken in (and maybe away). Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * SoundCloud: https://soundcloud.com/jeanette_c * Twitter: https://twitter.com/jeanette_c_s * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c Ain't no way I'll be lonely <3 (Britney Spears)

[Music] Cloud Castles (melodic Drum&Bass)

by Jeanette C.

Hey hey, I just released Cloud Castles: https://youtu.be/dLghAZpR9hk a melodic Drum&Bass track with quite some Linux support. Two tracks of Yoshimi, strings, trumpet, trombone and mellotron choir from LinuxSampler, drums, risers and special effects from Csound. The Csound elements were rendered to disk and then loaded into LinuxSampler using SFZ format. In processing TAP, CAPS and Fons' LADSPA plugins were used, as well as the Dragon Reverb LV2 plugin, loaded into mod-host. As ever MIDI sequencing and arrangement in Midish and all audio recording, mixing and processing in Nama.

New Debian install and usb device

by Mac

I have installed a fresh Debian 10 and I have Qjackctl installed. Qjackctl shows the ZEDi8 (though lsusb does not see it as a ZED, I think is does on Ubuntu...) But, I can't seem to get the config to actually get audio from the ZED, it appears to be using the onboard sound. My web searches have not provided any help...

threadirqs suspected to cause xruns

by Moshe Werner

Hello everyone, so I ran into trouble with a new machine I built recently. It appears to be that when I enable threadirqs or use an rt-Kernel, I am getting an xrun inferno. At first everything is fine but after a few seconds/minutes of playback I get thousands of xruns. I am on Manjaro (KDE), the kernels I tried so far are 5.8.3-2 - working ok'ish without threadirqs enabled 5.6.19_rt12-3 - bad 5.4.59_rt36-1 - bad The funny thing is that I had a nice running system at first (around two months ago) on the same machine, the xruns started suddenly out of the blue. (Kernel update?) Configuration is Ryzen 5 3600 B450 Aorus pro Motu 1248 Manjaro KDE I tried to higher the buffers to 2048, didn't help. I installed an USB2 PCIe card so that I could separate the usb audio interface from other stuff and prefer its IRQ with rtirq. Nothing helped. What could be wrong? I would love to hear your opinions Best regards Moshe Werner

help request: RT audio checkup and xorg's xruns

by Nicola Pandini

Hello list! I have a setup that I use in my live sets made with an ASUS N551 laptops and a NI Komplete Audio 6, which allows me to play without XRUNS at 64 frames / period with a modular approach (Qtractor, LinuxSampler, Yoshimi, SooperLooper, PureData). The whole thing runs on Debian Stretch with AVLinux 4.9.47-rt37avl2 kernel. I am quite happy with the performance of this setup, but I started having XRUNS when I added real-time video management as well. Those issues made me notice that the system runs without XRUNS only if XOrg is not stressed much, while it starts producing XRUNS when I play a video, or when I open the browser, or even when I quickly move or resize a window. I would like to understand if the problem is due to an incorrect configuration of realtime priorities, or to something that I have not yet managed to trap. I currently use these configurations: [Xorg] The video driver is i915. I read on the internet that: "If your graphic card was manufactured in 2007 and newer, try uninstalling the xserver-xorg-video-intel package and use the builtin modesetting driver (xserver-xorg-core) instead" Questions: - I uninstalled xserver-xorg-video-intel, but I still see the i915 driver: is that correct, or should I see another driver? [rtirq] RTIRQ_NAME_LIST = "snd usb i8042" RTIRQ_PRIO_HIGH = 90 RTIRQ_PRIO_DECR = 5 RTIRQ_PRIO_LOW = 51 RTIRQ_RESET_ALL = 0 RTIRQ_NON_THREADED = "rtc snd" Questions: - rtc must be in "NON_THREADED", or in "RTIRQ_NAME_LIST"? - in "RTIRQ_NAME_LIST" can I remove "usb" and put only the item that manages my USB card? Should it be xhci? - can i take i8042 off the list? - is it recommended to use RTIRQ_RESET_ALL = 1 to override all other IRQs? [jackd] jackd -P83 -dalsa -dhw: K6 -r44100 -p64 -n2 -I1 Questions: - the priority must be lower than those that are set to the IRQs by rtirq? [limits.conf] @audio - rtprio 99 # maximum realtime priority @audio - memlock unlimited # maximum locked-in-memory address space (KB) Questions: - what is the recommended value of rtprio in 2020? On the internet I find 90, 95 and 99 Can you help me do a checkup of my configuration? Thanks! -- Nicola Pandini http://nicolapandini.damai.it

KVR August contest

by Will Godfrey

I used to take part in this every month, but it's now been nearly a year since I last contributed. However I finally had a bit of inspiration and the result is here: https://archive.org/download/20-08-folderol-submundo/20-08_folderol_Submund… I don't think I need to say which synth I'm using, however this is the first occasion where I've used MIDI-learned controls to twiddle LFO and filter settings within the engines dynamically - although it's been possible for quite a long time. Hope you like it :) -- 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.
