Hi there, I'm new to the list. Composer/musician using Supercollider, I just moved from MacOS to Ubuntu 18.04. I was under the impression that the Edirol FA101 firewire audio interface should be working on Ubuntu, but I find it hard to figure out where to begin. The device is connected with an adapter to a Thunderbolt port on my Dell laptop. cat /proc/asound/cards does not show the device unfortunately. When I do lspci -tv in terminal, the Thunderbolt port seems to be recognized: +-1b.0-[02-3a]----00.0-[03-3a]--+-00.0-[04]----00.0 Intel Corporation JHL6340 Thunderbolt 3 NHI (C step) [Alpine Ridge 2C 2016] | +-01.0-[05-39]-- | \-02.0-[3a]----00.0 Intel Corporation Device 15db Can anyone point me in some direction for a solution to this? Thanks! Robert ★ Robert van Heumen software developer, composer, sound designer, improvisor west28.nl[1] -------- [1] west28.nl

- jackd audioadapter vs alsa_in & _out vs zita_a2j & _j2a

by Athanasios Silis

Hi all I am looking for some info on which client should one use in order to enable a 2nd sound card on the jack server or any of the jack client computers. I can see in zita's website that zita clients seems to be an improved versionnnnnn of alsa_in & _out clients, but I would like for other people to comment on that as well. Where I am completely in the dark is where audioadapter stands in all this ... Best regards, Athanasios

mcpdisp-0.1.2 release

by Len Ovens

MCPDISP is a utility to add a display on to a Mackie Control based control surface that does not have it's own display such as the bcf2000. This is important if banking is being used (the project has more than 8 tracks) and also provides things like timecode or bar/beat readouts. At present this is a jackd only utility though it should be possible to bridge to ALSA using a2jmidid. Perhaps a later version will move to ALSA MIDI instead. The latest version can be found at: https://github.com/ovenwerks/mcpdisp/releases/tag/mcpdisp-0.1.2 Some Packaging scripts were optimizing the buffer to the stack. This release fixes that. Licenced as GPL-2+. -- Len Ovens www.ovenwerks.net

[music] Early Music live stream concert from 5 different locations

by Giso Grimm

Dear LAUs, on July 7th, 2020, 6pm CEST our viola da gamba ensemble ORLANDOviols will play a concert, connected and streamed using FLOSS: The Gentle True Spirit a happy concert in these distracted Tymes http://www.orlandoviols.com/ free admission During these distracted times without concerts we developed an audio interface which allows us to play music together despite our spatial separation. We have been playing together in our virtual rehearsal room since mid April, exploring rarely played repertoire. This allowed us to develop a new concert programme revolving around the six-part Fantasies of the progressive young composer William Lawes, who unfortunately died much too young (1602-1645). This programme will be presented as a streaming concert: performed at five different locations simultaneously, connected through the internet. Your concert experience is not only about hearing - you can watch us playing in an interactive virtual space, arranged around you. Join us and explore! Viola da Gamba: Frauke Hess, Júlia Vető, Hille Perl, Marthe Perl, Giso Grimm, Claas Harders Streaming assistant: David Grimm Looking forward to 'meet'(*) you there! Best, Giso (*) Chat messages will be answered at the end of the concert

ALSA MIDI buffer size

by Brent Busby

I've been working on a problem with a Perl program sending and receiving large sysex dumps via the ALSA::MIDI module. It looks like there is a 4kB buffer in ALSA rawmidi that can be overrun if things go in or out too quickly. Keeping it from filling too fast outgoing is easy. But since there is no way for MIDI to tell the remote sender to slow down, preventing buffer overruns from incoming data is turning into a problem. Is there a way I can either tune the size of the buffer from Perl, perhaps with some kind of library call to ALSA's raw MIDI API, or somehow make the access blocking so that it won't try to take more data than it can handle? I've been looking at the C source for the amidi command, but I'm trying to deal with this in Perl if possible. It seems to depend a lot on how fast the device wants to send, but some devices break the sysex transfer into chunks and try to slow down, and other don't bother and just expect you to keep up.

[ANN] Qtractor 0.9.15 - An Early-Summer'20 Release

by Rui Nuno Capela

Hi y'all! Let's go straight to the real good news ;)... Qtractor 0.9.15 (early-summer'20) is released! Change-log: - Fixed MIDI tracks export that were missing the end-of-export tail parameter and bailing out always with default SMF format anyway. - Fixed VST3 component/controller inter-connection. - LV2 Atom/Port-event host notification support has been retouched, but still unofficial though. - Fixed VST3 audio-processor initialization/activation when a plugin has no inputs or outputs present. - Let main window pseudo-asynchronous stabilization re. menus, tools and status bars, just faster and immediate. - Fixed MIDI track monitor re-instantiation and reset. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Release: New Session Manager Version 1.3

by software＠linuxaudio.org

Linuxaudio.org presents: New Session Manager Version 1.3 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. It is a community version of the "NON Session Manager" and 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. New-Session-Manager is already included as binary package in Archlinux and KXStudio and will eventually replace Non-Session-Manager. You can find the source release on Github: https://github.com/linuxaudio/new-session-manager/releases/tag/v1.3 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 session manager for Linux distributions Changes since non-session-manager v1.2 (2017-07-08) * Rebranding to "new session manager" * Upstream GUI tools "non-session-manager" and "nsm-proxy" converted to standard FLTK instead of a custom toolkit * New message /nsm/gui/session/root raises NSM_API_VERSION_MINOR from 0 to 1 (1.0 -> 1.1) * Changed build system to meson * License upgraded to GPLv3 * Simplified file structure * Fix compiler warnings. This is a joint release from multiple people under the linuxaudio.org "brand". https://github.com/linuxaudio/new-session-manager Greetings, dvzrv, falktx and nils

Reverse-engineering MIDI software

by Caelia Chapin

Hi. I don't know if this is really the best place for this type of question, but I don't know where else to ask, so here is my question: I recently acquired an Arturia MiniLab MkII MIDI controller, and would like to use it with Linux applications (e.g. Ardour). The basic functions - i.e. playing notes with the keyboard and performance pads - work out of the box, but there are also some advanced functions that might be useful, which need to be enabled or configured through software. Arturia provides a "MIDI Control Center" for this controller, but of course it only runs on Windows and MacOS. I would like to be able to replicate the functionality of this software in Linux. It seems to me that it should be possible to run the MIDI Control Center in a Windows VM (I use VirtualBox for this), and use some sort of listener in Linux to display the MIDI messages that the Control Center is sending to the device. But I am not aware of any specific tools I could use for this purpose. Any recommendations?
