I built a new PC and installed Ubuntu Studio 16.04. The PC has a firewire card. lsmod | grep fire firewire_ohci 40960 0 firewire_core 65536 1 firewire_ohci crc_itu_t 16384 1 firewire_core ffado-diag claims these aren't there: libraw1394 .... libavc1394 .... libiec61883 ... libxml++-2.6 . But, apt says they are. jack_control fails to start the server if the firewire driver is selected. But, starts ok if alsa is selected. Not sure where to go from here. Any ideas/pointers appreciated. My last 3 PC's, UBS 16.04, firewire, jack, just worked OOTB. Mac

JACK netmanger to trigger the execution of a bash script on client connect/disconnect?

by Athanasios Silis

Hi all, after starting JACK2 manually (no DBUS, no KX studio session or anything automatic, other than starting it from /etc/rc.local on boot up) on jack master server, I also start the netmanager and wait for jack clients to connect. jack_load netmanager When clients connect I have them ssh to this jack master server and run a script about what connections are necessary between the master's sound card and the client's exposed ports. This is fine and works if jack clients lose lose connection and have to reconnect. This does not work well when something is wrong with the jack master and the audio is restarted. The clients will reconnect and the client will pop up (f.e. in qjackctl), but the necessary connections will not be reestablished. The ideal way to automate this would be to have jack master take care of all its connections and have netmanager trigger the execution of a script when a client connects. How can I do that without using application requiring an X server (thus a bash script)?? More specifically I want to know how I can trigger a script that carries out the connections, not what should the script contain... Thank you in advance for your help!

firewire-thunderbolt adapter?

by Bernardo Barros

Hello I have a quick question. I have an old MOTU Ultralite that works well with a thinkpad, which has a firewire I/O. Current Thinkpads don't have firewire, but some have thunderbolt. My old soundcard would work on a new thinkpad with an adapter, like it does with other OS's? Thanks! Bernardo

"Sonoj", a community organized event about Open Source Music Production struggles to get funded. Please help

by Nils, Sonoj Convention

(Disclaimer: I am an organizer of this event) In less than a month the "Sonoj Convention" shall happen. [quote]Admission is free. You will be able to enjoy demonstrations, talks and workshops about music production through open source software. Hands-on tutorials and workflow presentations can be expected. Everything will be recorded and released as online videos afterwards. [/quote] Please consider helping us by donating and spreading the word. You will get some appreciation through the "Reward" system on the website. For that we are asking for some modest donations here: https://www.startnext.com/en/sonoj Currently it looks like that this will not succeed, as you can see from the link above. This is the usual "all or nothing" platform that only gives you money if the goal is reached, otherwise donors get their money back. However, despite submitting the event announcements and several updates to nearly one hundred on-topic websites, magazines (including posting it ourselves on KVR, Reddit etc.) and blogs there is nearly zero response. That excludes the Linux Audio Scene itself, which was very supportive to this day (at least the news, not the donations). I was hoping that Sonoj could be an event that brings in people from the "outside", that are not already well connected with Linux Audio. It seems I was wrong. So here I am in one of the last places I wanted to ask for donations, because this is the crowd that usually already gives a lot, be it their own time, development of software or actual donations to well deserving projects. Please consider helping us by donating and spreading the word. You will get some appreciation through the "Reward" system on the website. https://www.startnext.com/en/sonoj Yours Nils, for the Sonoj Convention https://www.sonoj.org

changing ulimit from rc.local in order to start audio scripts from there

by Athanasios Silis

Hi there, I have setup an audio system around jackd based on ubuntu studio (14.04 LTS). I have written various scripts to setup jackd and clients. It is tested and up running. Now I would like to add a cmd in rc.local in order for the whole system to be brought up at boot. I tried #set limits su - nass -c "ulimit -r 95 -l unlimited" 2>&1 | tee -a /tmp/audio.log #verify limits su - nass -c "ulimit -r -l" 2>&1 | tee -a /tmp/audio.log #boot audio stuff su - nass -c "cd /home/nass/audio_setup/scripts ; bash ./cmdaudio start" 2>&1 | tee -a /tmp/audio.log However the ulimit "set" command fails with message ulimit: real-time priority: cannot modify limit: Operation not permitted I read that ulimits are not ready yet at this time. Is there a way to forcefully "bring them up" in order to have them set for the user "nass" before starting the audio scripts ?? Thank you

how can I send a midi command from bash through jack to my HW controller?

by Athanasios Silis

Hi all, I have a BCR2000 and would like to use a script to set some values on these knobs and buttons. amidi should be able to help me do that but I somehow cannot properly set the name of the port in order to use it. Note, jackd server is up and running and then I also use the "aj2midid" midi bridge to populate hw and software midi ports in jack, So even though I thought this would be easy , I am stuck somewhere. The command I am trying to use is amidi -p"14:0" -S <3x bytes depicting the midi CC command> now port "14" SHOULD be the "Midi Through port as it appears in qjackctl's "midi" tab. I got it from $ aconnect -i -o client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' client 14: 'Midi Through' [type=kernel] 0 'Midi Through Port-0' client 16: 'TerraTec DMX6Fire' [type=kernel] 0 'MIDI-Front DMX6fire 0' 32 'Wavetable DMX6fire 0' client 24: 'Hoontech SoundTrack Audio DSP24' [type=kernel] 0 'MIDI-1 Hoontech/STA DSP24 2' 32 'MIDI-2 Hoontech/STA DSP24 2' client 28: 'Hoontech SoundTrack Audio DSP24' [type=kernel] 0 'MIDI-1 Hoontech/STA DSP24 3' 32 'MIDI-2 Hoontech/STA DSP24 3' client 32: 'BCR2000' [type=kernel] 0 'BCR2000 MIDI 1 ' 1 'BCR2000 MIDI 2 ' 2 'BCR2000 MIDI 3 ' but running "amidi -p14:0 -S <hexbytes>" returns cannot open port "14:0": No such file or directory What am I doing wrong? thank you in advance for your help
