| usub | I have a fresh snapshot at the system and would like to get simple recording working in Jack | 17:27 |
|---|---|---|
| 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 | 17:28 |
| OvenWerks | if yu are using ubuntustudio-controls you can't have cadence and the reverse | 17:29 |
| 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 | 17:30 |
| 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 | 17:31 |
| 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 | 17:32 |
| usub | OvenWerks: I'm not clear on what "backport" means. Would you enlighten me? | 17:33 |
| usub | more software? newer software? older software? | 17:33 |
| 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 | 17:34 |
| 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 | 17:35 |
| OvenWerks | I think there are a few fixes since 19.04 | 17:36 |
| 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 :) | 17:37 |
| 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 | 17:38 |
| OvenWerks | you are welcome to install as much as you want... do be warned, it will take a while | 17:39 |
| usub | I take audio and lowlatency now | 17:40 |
| usub | install more if I get this to work | 17:40 |
| 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. | 17:41 |
| 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. | 17:42 |
| 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 | 17:43 |
| 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 | 17:44 |
| 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 | 17:45 |
| usub | I'm excited to see what I can make happen audio-wise | 17:46 |
| usub | usub.. the nicks one comes up with when needing two ircs.. | 17:48 |
| usub | kinda got a 2 laptop situation | 17:48 |
| 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 | 17:50 |
| 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 | 17:51 |
| OvenWerks | Ya | 17:52 |
| usub | and I do pay irccloud 4€ / month | 17:52 |
| usub | perhaps I should connect as my irccloud on the browser instead of running a konversation | 17:53 |
| 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 | 17:56 |
| Eickmeyer | !kxstudio | 17:58 |
| ubottu | KXStudio is an Ubuntu-based operating system and a repository for Debian-based operating systems for audio production. Development is on hiatus until late-2019 as of this writing. It is not supported by Ubuntu or Ubuntu Studio, and using its repo is discouraged. Support in #kxstudio. | 17:58 |
| wonko | I think jackd is crashing. Does that log somewhere? I'm not able to figure out if/where it does. | 18:01 |
| OvenWerks | wonko: ~/.log | 18:03 |
| OvenWerks | maybe ~/.log/jack | 18:04 |
| wonko | Ok, I'll try looking there, thanks! | 18:26 |
| usub | logout for RT access. bbiab | 19:06 |
| OvenWerks | usub: if you install more stuff, you can ignore the logout and in message a second time. | 19:10 |
| OvenWerks | installer puts that out at the end of an install regaurdless. | 19:11 |
| 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 | 20:44 |
| usub | but Ardour is able to record | 20:48 |
| usub | Happy time! | 20:49 |
| 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 | 20:55 |
| usub | or actually I'm going to install the rest of the Ubuntu Studio now | 20:56 |
| OvenWerks | if it shows up as an alsa midi device the midi bridge in ubuntustudio-controls should make it show up as a2j-<something> | 20:57 |
| usub | OvenWerks: thanks. now it shows up in the patchbay | 21:14 |
| usub | now I connected it to fluidsynth, but fluidsynth has no outputs | 21:15 |
| OvenWerks | look for qsynth for fluid synth outputs? | 21:27 |
| OvenWerks | usub: ^^^ | 21:28 |
| 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 | 21:31 |
| 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 | 21:38 |
| OvenWerks | Do you have a sound font loaded? | 21:42 |
| wonko | That sound font thing too me forever to figure out when I first used qsynth | 21:45 |
| wonko | Took* | 21:45 |
| OvenWerks | Ya they are kind of hidden | 21:46 |
| mobijubo | OvenWerks: Good point. Without a sound-font it will not play much sound | 21:56 |
| usub | ok, now loaded soundfont and I get audible sounds from the midi controller | 22:03 |
| usub | there is horrible lag in the synthesizer | 22:03 |
| usub | I've had fluidsynth that is very fast | 22:04 |
| OvenWerks | in jack what do you have buffer size set to? | 22:06 |
| OvenWerks | if it is 1024 maybe reduce that to 128 and try again. | 22:07 |
| usub | 4096 | 22:08 |
| OvenWerks | Thats pretty long ya | 22:08 |
| OvenWerks | even 1024 should be nicer than that | 22:08 |
| OvenWerks | 1024 is default and has worked for me | 22:09 |
| OvenWerks | 128 is the lowest that many USB devices work reliably at | 22:09 |
| OvenWerks | I have run 16 on a PCI device | 22:10 |
| usub | Cheers OvenWerks .. worked much better with low latency | 22:27 |
| 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 | 22:28 |
| wonko | OvenWerks: http://paste.ubuntu.com/p/pSyg52FXZW/ | 23:42 |
| wonko | Oh that's very long, sorry | 23:43 |
| wonko | But the errors at the bottom might mean something to you? | 23:44 |
