Can netjack1/2 over a direct ethernet connection substitute for local ALSA audio?

by crocket

I have a desktop computer and Raspberry Pi 3 B+. I want Raspberry Pi to control my speakers and share my speakers with my desktop over a direct ethernet connection. USB microphone is going to be connected to Raspberry Pi and be shared with the desktop computer over the ethernet connection, too. Can netjack1/2 over a direct ethernet connection substitute for local ALSA audio? Will video and audio synchronize if netjack was used over a direct ethernet connection?

How can I detect whether JACK or ALSA clients are using an audio gear?

by crocket

My Raspberry Pi can turn audio gears on and off via relays. When my desktop starts using its speakers, I want it to tell Raspberry Pi to turn on the speakers via a relay. When nothing has used the speakers for a minute, I want it to tell Raspberry Pi to turn off the speakers. I can do the same for a USB microphone. A USB microphone can be turned on and off by uhubctl. Does ALSA have a callback API that I hook into? Does jack have it?

A shout out to instrument patch makers

by Will Godfrey

For Yoshi and Zyn, there are a very large number of patches that have no copyright/license information filled in. In the first place this makes it impossible to give any kind of acknowledgement. Potentially more critical is the new messy copyright legislation staggering through the EU. I don't know if there is any practical way of adding this to old files, but at least when creating new one *please* fill these fields in - even if you don't think you'll ever release them. As and aside, a lot of these also have no 'Type' filled in :( Apologies for the cross post - not really sure where this should go. -- 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.

How to get a persistent midi instrument source port? ( lightweight )

by hgn

Dear list, to avoid the https://en.wikipedia.org/wiki/XY_problem I'm going to tell you my goal first, then my current route to a solution, with a missing piece. I work with several midi instruments. Some of them USB, some of them DIN, all of them have different names. Only ever one is connected at once. I want my programs to accept data entry from my instruments, no matter which of them is plugged in. What is the easiest way to do this? My current idea is to establish a virtual jack midi thru port. All software can use this port as midi data source. Hardware instruments then get be connected via one of the many auto-connector solutions: The one built into QJackCtl or https://github.com/SpotlightKid/jack-matchmaker , which is what I am using already. The virtual jack midi port is the missing piece. What is the best way to get one? "Best" means least resources, least administration overhead. E.g. any answer involving the words "plugin host" is already too much. Ideal would be a simple daemon program I can autorun after starting jack (with qjackctl script-after-start) So I am either looking for that midi thru port or a different solution that works even better. -hgn P.S. In case the JACK devs are reading: AFAIK Jack works under the assumption that audio System out 1 and 2 are the main abstracted stereo outputs and are available on any system. This leads to great portability across all systems. I consider midi data entry with a single instrument an equally typical use case and would like to propose to add a single midi thru port to JACK directly. No more, no less, nothing to configure, nothing to check for as user or developer.

Re: [LAU] sound devices usb pre 2. usb 2 with 96k

LAC steaming to c-base, Berlin

by Robin Gareus

Hi all, A group of people who do not attend the Linux Audio Conference in Stanford this year are meeting at c-base.org to participate remotely. http://lac.linuxaudio.org/2019/#program We'll watch the live-stream of the paper-presentations on Saturday, Sunday, Monday 17h to 21h CET, and share dinner, which is sponsored by the Paul Davis and the Ardour community! You're very welcome to join our small local hallway track in the space station below Berlin-Mitte, located in the 2nd backyard of Rungestraße 20, 10179 Berlin. There'll also some un-conference BarCamp track, likley some LV2 hacking on the week-end. Monday evening overlaps with the Bitwig user-group at c-base. Going to be fun! Looking forward to seeing you there, robin PS. Safe travels to all who head to Stanford.

[ANN] Qtractor 0.9.6 - The Pre-LAC2019 Release Frenzy wrap-up!

by Rui Nuno Capela

Hi again, For last but not least and concluding the so called traditional pre-LAC2019 [8] release frenzy: Qtractor 0.9.6 (pre-lac2019) is released! Here the last changes included for this wrap-up release: - Fixed LV2 UI Touch feature/interface implementation. - Plugin latency/delay compensation is now introduced as an option to tracks only (cf. Track/Properties.../Latency compensation). - Refactored all singleton/unique application instance setup logic away from X11/Xcb hackery. - A bit lesser of a naive file-name numbering is now in place to avoid as much as possible, the piling up of internal curve/automation files when saving existing sessions. - Maybe just informational but the original MIDI file format is now correctly reported across ref-counted linked MIDI clips. 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.
