Linuxaudio.org presents: New Session Manager Version 1.5.0 ## Summary WARNING! Next scheduled release (2021-04-15) will switch the default session root to $XDG_DATA_HOME ( default on most distributions: ~/.local/share/nsm/ ) With Aprils release please prepare to do one of the following: * Move old sessions to the new root directory (preferred) * Symlink "~/NSM Sessions" to the new root directory * use the nsmd --session-root commandline argument. All changes are made only on the server side, or in the tools we provide. Existing sessions, clients, and GUIs remain 100% compatible without requiring any changes. Please see the CHANGELOG highlight below. The project can be found on Github: https://github.com/linuxaudio/new-session-manager/ https://github.com/linuxaudio/new-session-manager/releases/tag/v1.5.0 API Document: https://linuxaudio.github.io/new-session-manager/api/index.html ## Full Release Announcement: New Session Manager (NSM) is a tool to assist music production by grouping standalone programs into sessions. Your workflow becomes easy to manage, robust and fast by leveraging the full potential of cooperative applications. NSM is free in every sense of the word: free of cost, free to share and use, free of spyware or ads, free-and-open-source. You can create a session, or project, add programs to it and then use commands to save, start/stop, hide/show all programs at once, or individually. At a later date you can then re-open the session and continue where you left off. All files belonging to the session will be saved in the same directory. Check your distributions in a few days for New-Session-Manager 1.5.0 You can find the source release on Github: https://github.com/linuxaudio/new-session-manager/releases/tag/v1.5.0 Bullet Points * Drop-In replacement for the non-session-manager daemon nsmd and tools (e.g. jackpatch) * Simple and hassle-free build system to make packaging easy * Possibility to react to sensible bug fixes that would not have been integrated into original nsmd * Stay upwards and downwards compatible with original nsmd * Conservative and hesitant in regards to new features and behaviour-changes, but possible in principle * Keep the session-manager separate from the other NON* tools Mixer, Sequencer and Timeline. * Protect nsmd from vanishing from the internet one day. * The goal is to become the de-facto standard music session manager for Linux distributions # Changes since new-session-manager v1.4.0 (2020-08-14) All changes are made only on the server side, or in the tools we provide. Existing sessions, clients, and GUIs remain 100% compatible without requiring any changes. ## nsmd: * Fix session discovery to not report nested sessions anymore. Also more robust file system error handling. * Command line option --quiet: Suppress messages except warnings and errors * Protect against orphaned clients or daemons when the server, or even a GUI, crashes. * Replace cowboy-slang in info-level OSC with descriptive, technical messages. ## Legacy-GUI: * Fix manpage description and usage with the correct executable name * Fix resizing to very small and back. ( / TheGreatWhiteShark ) ## NSM-Proxy: * Multiple layout and style fixes. Better texts for beginners. ## API: * NSM_API_VERSION_PATCH from 0 to 1 (1.1.0 -> 1.1.1) * Please see API document chapter "Changes in API Version 1.1.1" ## Extras: * This repository now contains extras (libraries, programs, documentation etc.) Extras are technically not connected to the main programs of this repository. There is no dependency to any "extra" nor any license implications. Please read extras/README.md. * nsm.h was moved to extras/nsm.h * "extras/pynsm" is now a part of NEW-SM. It was a standalone git repo until now. Greetings, nils

Firewire latency

by Len Ovens

Playing around with an Audiofire 12 and I have just found an interesting limitation in latency settings. I can easily set my system up to use the audiofire to use either the alsa drivers or the ffado drivers and have tried both. I found an interesting result: using the alsa driver my minimum latency when using JACK is 256/2. If I try 128/3 (or 128/2) JACK locks up and needs kill -9 to get rid of. Using the FFADO drivers I have been running JACK at 32/2 for over an hour with only 1 xrun for the whole time. So my question for anyone else who has or is using a firewire device is: Do you also have a similar experience? And which distro? I am mainly asking for documentation reasons for Studio-controls -- Len Ovens www.ovenwerks.net

LV2/MIDI plugins missing in Ardour

by Michael Jarosch

Hi, there! My son brought to my attention, that my debian testing based media machine has some trouble finding some LV2 plugins with Ardour, although they are installed on the system. Must have been happen a few days ago with a simple use of "apt upgrade", 'cause he said that the last time he fiddled on some tracks everything was just in place. At least, there are three plugins he would like to use, which are not there anymore: drumkv1, samplv1 and odin2. drumkv1 and samplv1 are from debians repository, odin2 is from the homepage of "TheWaveWarden" (https://www.thewavewarden.com/odin2) - it has some packaging issues (the name of the package is the same as another package in debian's repository) but I can't imagine this has something to do with my problems. drumkv1 and samplv1 got upgraded, recently. But the Ardour package is the same since october… I already tried a new scan for plugins from inside Ardour, but all I got was some VST plugin additions which is nice but not what I intended to get. So, I'm a bit confused: There are some LV2 plugins from /usr/lib/LV2 that are usable from within Ardour and some are not. I just don't know, what to do, now… Greets! Mitsch

[Music] Sharp

by Jeanette C.

Hey hey, Sharp is a new melodic Drum&Bass track: https://youtu.be/qJoML_QdhKo And for direct OGG download: https://www.dropbox.com/s/5i3gif5x6dkkk11/sharp.ogg On Linux I used Yoshimi for pads, stabs, plucks and one bass, LinuxSampler to play drums and some effects as well as a Solina (for more bass) and finally Csound to create the main drums, effects and risers. Naturally, I enjoyed Midish, Nama and a lot of plugins for the recording and production. Additionally, some hardware was involved for 808-style drums, more pads, Bass(!) and the main lead. Feedback is welcome, but mostly: share and 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 Just hang around and you'll see, There's nowhere I'd rather be <3 (Britney Spears)

[music] Power Girl (glam)rock ballad

by Jeanette C.

Hey hey, Power Girl is the latest track, unfortunately another instrumental, but a quite densely arranged one. https://youtu.be/-wSfh7600tQ And as an OGG: https://www.dropbox.com/s/3nhpjuz21xgsiyk/power_girl.ogg On the hardware side it features the Clavinet, once processed through Fons Adriaensen's autowah and once through a lot of Guitarix goodness. Furthermore> Yoshimi for choir stabs, Fluidsynth for bass, setBfree (for... organ :) ) and LinuxSampler for drums, tron choir, SSO strings, clock ticks and muted piano effect. Add loads more plugins and some more hardware and we're done. Feedback, as ever, is very welcome. Enjoy and a happy new, energetic year, 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 Skip on the drinks Head to the floor Makin' my way Past the show My body's taken over And I want some more <3 (Britney Spears)

JACK2 hardware buffer size for browser-based video conferencing

by Andrew A. Grathwohl

Hi folks, I have a question about my microphone audio quality when participating in a browser-based video conference, i.e., Google Meet and Jitsi on chromium browser. Starting last week, I have received numerous reports from coworkers that my audio is considerably higher quality than normal. Although my audio input has always been a high end vocal mic, the reports have indicated that I sound even better than I usually do in these conferences. My daily driver machine is a self-built Xeon workstation running Arch Linux with (I think) a well-configured RT kernel and JACK2, whose configuration if optimized for USB audio interfaces via this guide <https://wiki.linuxaudio.org/wiki/list_of_jack_frame_period_settings_ideal_f…> [0]. I use a Peluso mic connected directly to my RME Babyface Pro interface, which is running via one of my system's USB2 ports. In pursuit of understanding why this is occurring, I looked at my JACK2 settings to see if I'd changed anything lately. Sure enough, I noticed that I have been working at a larger JACK2 hardware buffer size than normal. I typically set my size to 64 since I do a lot of real-time audio work, but have had it set to 256 or 512 lately to do some different kinds of stuff on the system. So, my question boils down to: is it reasonable to suspect the hardware buffer size has something to do with these sudden quality improvement reports from my friends & co-workers? If so, any insights into why this is the case would be greatly appreciated. Cheers, Andrew [0] https://wiki.linuxaudio.org/wiki/list_of_jack_frame_period_settings_ideal_f…

Force usb-audio device into 44100

by Atte Jensen

Hi I recently got a uTrack24 that I'm gonna use as an audio interface. It works fine, but seems to have a will of it's own, most of the time it starts in 48000, most of the time it eventually switches (seemingly by it's own) to 44100. Frankly I'm not really sure when it does what. Problem is that if I start qjackctl in 44100 it might still hang in 48000 and the audio files will be 48000 with a header indicating 44100. I can fix this with sox, but obviously it should rather work correctly. In any case, is it possible to force it into always using 44100hz, by matching the usb ids with some ALSA(?) config file? If so, a few hints to get me started would be highly appreciated :-) Cheers -- Atte http://latestyoutube.a773.dk
