[17:27] <usub> I have a fresh snapshot at the system and would like to get simple recording working in Jack
[17:28] <usub> I was told that KDE may be causing the problems because it uses a backend canned phonon, but I'd like to give it a try
[17:28] <OvenWerks> Ok, Jack itself doesn't record, which application would you like to use?
[17:28] <usub> so.. I can get cadence from KX Studio or Ubuntu Studio repos, right? And trying to install both repos could lead to troubles perhaps
[17:29] <OvenWerks> if yu are using ubuntustudio-controls you can't have cadence and the reverse
[17:30] <OvenWerks> cadence makes system changes that are difficult to reverse.
[17:30] <usub> OvenWerks: 'apt search ubuntustudio' (on a Kubuntu 18.04.3) shows a bunch of stuff
[17:30] <OvenWerks> This is because it installs almost everything in user space rather than system.
[17:30] <OvenWerks> What do you have installed so far?
[17:30] <usub> what should I install to get the repos
[17:31] <OvenWerks> Are you starting from kubuntu?
[17:31] <usub> I'm willing to try other distros
[17:31] <usub> OvenWerks: yes, from kubuntu
[17:31] <OvenWerks> kubuntu is fine, I have had no trouble doing that
[17:32] <OvenWerks> so: sudo apt install ubuntustudio-installer
[17:32] <usub> and then run that?
[17:32] <OvenWerks> ya, I would suggest first adding the ubuntustudio backports PPA
[17:33] <usub> OvenWerks: I'm not clear on what "backport" means. Would you enlighten me?
[17:33] <usub> more software? newer software? older software?
[17:34] <OvenWerks> A newer version of installer itself.
[17:34] <usub> So backports == good for us?
[17:34] <OvenWerks> sudo add-apt-repository ppa:ubuntustudio-ppa/backports
[17:35] <OvenWerks> ya, backports means you get the latest released version that will come out when 19.10 is released
[17:35] <OvenWerks> sudo apt-get update
[17:35] <OvenWerks> then sudo apt install ubuntustudio-installer
[17:35] <usub> OvenWerks: always a good idea to refresh the database of software after installing more repos
[17:36] <OvenWerks> I think there are a few fixes since 19.04
[17:37] <usub> now installing the new installer
[17:37] <usub> done
[17:37] <usub> what now?
[17:37] <usub> run it?
[17:37] <OvenWerks> run that and choose packages :)
[17:38] <usub> Awesome! Thank you all you people who make this possible
[17:38] <OvenWerks> If it is just audio you are interested in you may not want publishing, graphics
[17:38] <OvenWerks> *in audio
[17:38] <usub> I just did some work with Inkscape for a friend
[17:39] <OvenWerks> you are welcome to install as much as you want... do be warned, it will take a while
[17:40] <usub> I take audio and lowlatency now
[17:40] <usub> install more if I get this to work
[17:41] <usub> Hold on.. it is installing a 4-branch kernel, the kubuntu uses 5 now with 18.04.3
[17:41] <usub> is this going to be problems?
[17:41] <OvenWerks> it should not be.
[17:42] <usub> and I don't need anything fance, simple recording and I would love to get it to work that I can play something on the midi controller and then actually play it back
[17:42] <OvenWerks> The only problem would be if you need a graphics driver that is newer.
[17:43] <usub> OvenWerks: Nah running on 2012 released CPU
[17:43] <usub> once one gets used to how quick apt installs are with SSD they seem to take a long time on HDD
[17:43] <OvenWerks> your old kernel is not removed, so you can always choose that to boot
[17:44] <usub> OvenWerks: I put 50 GB for root partition, not running out
[17:44] <OvenWerks> I have used as low as 20G but my working one is 40G
[17:45] <usub> I ran out with 20GB some years ago
[17:45] <usub> needed to locate and manually remove old junk that some code stopped keeping track of
[17:46] <usub> I'm excited to see what I can make happen audio-wise
[17:48] <usub> usub.. the nicks one comes up with when needing two ircs..
[17:48] <usub> kinda got a 2 laptop situation
[17:50] <OvenWerks> I run screen with irssi so I can access it from whatever computer I happen to be using. Plus I can see the backscroll better
[17:51] <OvenWerks> screen is a text based session manager and irssi is a text based irc client]
[17:51] <usub> OvenWerks: I believe screen is a multipurpose session multiplexer like tmux is
[17:52] <OvenWerks> Ya
[17:52] <usub> and I do pay  irccloud 4€ / month
[17:53] <usub> perhaps I should connect as my irccloud on the browser instead of running a konversation
[17:56] <usub> that's me, but I like using konversation, but when I'm mobile I use the irccloud, coz it very good program for a phone irc.. right now I need to let the installation finish and hop over to the market to catch some grub
[17:58] <Eickmeyer> !kxstudio
[18:01] <wonko> I think jackd is crashing. Does that log somewhere? I'm not able to figure out if/where it does.
[18:03] <OvenWerks> wonko: ~/.log
[18:04] <OvenWerks> maybe ~/.log/jack
[18:26] <wonko> Ok, I'll try looking there, thanks!
[19:06] <usub> logout for RT access. bbiab
[19:10] <OvenWerks> usub: if you install more stuff, you can ignore the logout and in message a second time.
[19:11] <OvenWerks> installer puts that out at the end of an install regaurdless.
[20:44] <usub> now jack is up with pulseaudio working, but Audacity shows up in the patchbay as PortAudio in_1, in_2 and in_3, but I cannot link from system capture to the Audacity PortAudio
[20:48] <usub> but Ardour is able to record
[20:49] <usub> Happy time!
[20:55] <OvenWerks> Audacity does not do jack right.
[20:55] <usub> Next I need to figure out how to get jack to recognize my midi controller
[20:56] <usub> or actually I'm going to install the rest of the Ubuntu Studio now
[20:57] <OvenWerks> if it shows up as an alsa midi device the midi bridge in ubuntustudio-controls should make it show up as a2j-<something>
[21:14] <usub> OvenWerks: thanks. now it shows up in the patchbay
[21:15] <usub> now I connected it to fluidsynth, but fluidsynth has no outputs
[21:27] <OvenWerks> look for qsynth for fluid synth outputs?
[21:28] <OvenWerks> usub: ^^^
[21:31] <OvenWerks> usub: Ya, I used jack keyboard into the fluid synth midi in (in a2j) and qsynth out to audio outputs and I get noise
[21:38] <usub> this is weird, qsynth is connected to outputs and in the gui I can see it is getting the key presses, but no sound
[21:42] <OvenWerks> Do you have a sound font loaded?
[21:45] <wonko> That sound font thing too me forever to figure out when I first used qsynth
[21:45] <wonko> Took*
[21:46] <OvenWerks> Ya they are kind of hidden
[21:56] <mobijubo> OvenWerks: Good point. Without a sound-font it will not play much sound
[22:03] <usub> ok, now loaded soundfont and I get audible sounds from the midi controller
[22:03] <usub>  there is horrible lag in the synthesizer
[22:04] <usub> I've had fluidsynth that is very fast
[22:06] <OvenWerks> in jack what do you have buffer size set to?
[22:07] <OvenWerks> if it is 1024 maybe reduce that to 128 and try again.
[22:08] <usub> 4096
[22:08] <OvenWerks> Thats pretty long ya
[22:08] <OvenWerks> even 1024 should be nicer than that
[22:09] <OvenWerks> 1024 is default and has worked for me
[22:09] <OvenWerks> 128 is the lowest that many USB devices work reliably at
[22:10] <OvenWerks> I have run 16 on a PCI device
[22:27] <usub> Cheers OvenWerks .. worked much better with low latency
[22:28] <usub> but now I'm seeing something that after restarting jack things are not working as it looks in Carla. I better reboot this once
[23:42] <wonko> OvenWerks: http://paste.ubuntu.com/p/pSyg52FXZW/
[23:43] <wonko> Oh that's very long, sorry
[23:44] <wonko> But the errors at the bottom might mean something to you?
