alex-EUfalktx: A question. Can carla be run from the CLI, with a file name for a project? I'm thinking once i have a stable template, i'm going to pretty much use the same one regularly.15:21
falktxsure, just add the file after carla15:22
falktxcarla file.carxp15:22
falktxcarla-single can load single plugins, but doesn't work properly for wine stuff (no idea why...)15:23
alex-EUfalktx: ok,thanks. I'm not likely to use carla-single as a matter of normal use.15:24
alex-EUfalktx: just trying to find out what i can and cannot do. :)15:24
falktxnote that by default every carla instance will try to restore the jack connections15:25
alex-EUfalktx: yep, i'm glad it does.15:25
falktxit can be turned off with "CARLA_DONT_MANAGE_CONNECTIONS" env var15:26
alex-EUfalktx: if you mean the patchbay plugin.15:26
alex-EUfalktx: ok.15:26
falktxI mean in jack driver mode15:26
alex-EUfalktx: aah, ok. At the moment with the patchbay plugin, when the project starts up, everything seems to be routed as i want it to be.15:27
alex-EUfalktx: the midi routing works with my (now numerous) midi thru ports. so as long as the daw is pointed to those ports, i'm good to go.15:28
alex-EUfalktx: sorry, another question about state. I noted yesterday the control messages checkbox was off, and i had to enable it manually for each plugin instance. If i save the entire project, will these changes be saved as well? I tried early this morning, but couldn't seem to get them to stick.15:29
falktxthose changes are supposed to be saved15:30
falktxif not it's a bug15:30
*** wolftune has joined #kxstudio15:31
alex-EUfalktx: ok.15:32
alex-EUfalktx: just tried again, and it worked. I'll put it down to a gremlin, and push on.15:39
*** lfzawacki has quit IRC15:40
alex-EUfalktx: when i close carla, sometimes the bridge crashes. Just happened, and here's the terminal output: http://pastebin.com/VukDcsQg15:47
alex-EUfalktx: and here's the jackcli info: http://pastebin.com/6Zt5k4rC15:49
alex-EUfalktx: Carla closing too early for the K plugins?15:50
falktxclosing some plugins make the last ones wait too much15:51
falktxsame thing as before, I'll just have to disable the ping checks when starting to close15:51
alex-EUfalktx: right.15:51
alex-EUfalktx: ok15:52
falktxnothing serious15:52
alex-EUfalktx: one more question for now. (sorry for the noise). Can i run carla without the gui?15:52
falktxnot yet15:54
alex-EUfalktx: ok.15:54
falktxI can add some command-line argument for this if you want15:54
spectromasfalktx: I still can't get renoise to see carla as an effect, all show as instruments15:55
alex-EUfalktx: yep.15:55
alex-EUfalktx: thanks.15:55
falktxalex-EU: can I ask you to fill a quick bug report for this? (so that I don't forget)15:55
falktxhttps://github.com/falkTX/Carla/issues/15:56
falktxspectromas: same^15:56
alex-EUfalktx: i'd be interested to know if running from cli improves or worsens performance.15:56
alex-EUfalktx: ok.15:56
spectromasok falktx thanks15:56
alex-EUspectromas: too slow. :)16:00

wolftunefalktx: why doesn't Pianoteq show in Carla?17:08
wolftunebtw, the multichannel bridge output is working!17:08
falktxthe lv2 libs (lilv) have some issues with plugins with spaces in the filename :(17:09
*** HarryHaaren has joined #kxstudio17:09
falktxpianoteq-vst should work17:09
wolftunehmm17:11
reen-igurus here?17:12
holsteinreen-i: just volunteers here, volunteering support for users17:13
holsteinreen-i: patient users..17:13
reen-ii need not trols17:13
holsteinreen-i: ones who do not threaten contacting freenode on them ;)17:13
reen-iwhat do u mean?17:13
holsteinreen-i: the way *all* these channels work is, you just ask... if a volunteer can assist, they do17:14
holsteinreen-i: you threatened me last time i was assisting you17:14
reen-ii will report all trolls not only u17:14
holsteinfreenode doesnt promise you a "troll-free" experience, and i was *not*, and do *not* troll17:14
*** reen-i has left #kxstudio17:15
wolftuneoops17:15
wolftuneI was *about* to say that I can confirm that holstein, you are NOT a troll :P17:15
wolftunebut they left17:15
falktxtime to ban him17:15
holsteinwolftune: we have a history.. an unfortunate one :/17:15
*** ChanServ sets mode: +o falktx17:16
*** falktx sets mode: +b reen-i!*@*17:16
holsteinhe was calling me a troll, because i was explaining why his creative sb card wouldnt be able to do 96k in linux well.. but, also, its not a pro audio card.. and also 96k is not necessary17:16
wolftune96k is useless17:17
holsteini mean, if you want 96k, get a device that does it.. wont bother me at all.. anyways, i wish him well17:17
wolftune48k is perfectly fine for basically everything17:17
alex-EUholstein: that's terrible. How could you.... :)17:17
holsteinalex-EU: i know, a fair and balanced reporting of the facts.. freenode must be notified! ;)17:17
alex-EUholstein: To crush a troll's dream so ruthlessly........17:18
wolftunethe only nyquist effect issues of 96k  are the fact that inaudible high harmonics recorded at high frequences can create difference tones when combined in mixing17:18
holsteinanyways, he's probably just used to tech support, and doesnt understand how the hardware gets supported17:18
wolftuneunless you are studying bats or something17:18
holsteinwolftune: i was saying, "only your dog will notice, anyway" :)17:18
wolftunefalktx: apparently, it's not as simple as renaming the files17:21
wolftunefalktx: how could I get the new Pianoteq5 installed over the older Pianoteq4? I can just run it manually from a plain old directory… I17:22
wolftunewould rather it be installed into the system though17:22
alex-EUholstein: I've been accused of being troll by linux devs before, when i dared suggest there are users who want more than 40 tracks in an app............17:22
alex-EUholstein: I found it most amusing...........17:22
wolftuneI know you're not big on proprietary stuff and handling that (and I support that! I just wish other synths supported full 16-channel in one instance like Pianoteq does)17:23

JackWinterholstein: i think debianuser helped him to get it running at 192k, but won'd do 88k1 nor 96k18:25
JackWinterif i understood correctly he proceeded to want to play 32b audio instead of 24b :)18:27
JackWinterwith such aspirations one probably should invest in a better soundcard :)18:27

*** shiggitay has joined #kxstudio19:02
alex-EUfalktx: when i start a K instance standalone, i can set the priority. When i start carla with similar params, i still see the bridges in htop as a low, or normal priority19:03
alex-EUfalktx: Am i reading this right, have the wrong impression of what's supposed to happen?19:03
falktxit's a new process so yes19:03
*** shiggitay has left #kxstudio19:04
alex-EUfalktx: ok. So it's not really worth using those params when i start carla?19:04
alex-EUfalktx: it's only the bridges/wine that would use them, yes?19:05
falktxI can't say for sure, I don't know much about setting priorities in processes via code19:05
alex-EUfalktx: ok.19:05
falktxthese are the sort of things I leave for last19:06
falktxI'll need to do some studying to understand it19:06
alex-EUfalktx: right.19:06
falktxalso, it's not the full app/bridge that needs higher priority, only the process thread19:07
falktxmaking the full thing run in higher prio might have bad results19:07
alex-EUfalktx: yep, that's what i'm wondering19:08
falktxthis needs SCHED_FIFO or SCHED_RR or something, as I said don't know enough yet19:08
alex-EUfalktx: ok, i'm only asking out of curiosity.19:09
JackWinterfalktx: what's the best way to use vst plugins with ardour?19:10
falktxJackWinter: it already loads native ones19:10
JackWinterah cool, then i have to try to set it up.  you just have to point it as the vst path?19:10
JackWinterbeh, i meant windows ones...:)19:11
falktxI don't use ardour, but they have a build option for windows vsts19:12
falktxbetter ask them anyway19:12
JackWinterok, thanks19:12
falktxJackWinter: if you want to try carla + win bridges (like alex-EU runs on debian), you can install stuff from AUR19:12
falktxcarla-git and carla-bridge-win32-git ? I think19:12
falktxJackWinter: with that you get carla as lv2 and vst plugin, which works in ardour19:14
falktxI recommend the lv2 over the vst one19:14
JackWinteryeah, i might give that a try this weekend.  think i have carla installed, but not the wine bridges19:16
falktxthis new stuff is not on aur though19:16
JackWinterstill have to fix up some really fucked up pkgbuilds that i inherited though19:17
falktxor maybe it is hmmm19:17
falktxJackWinter: looking at aur, the -git packages seem to be good19:18
falktxjust don't use "carla" or "carla-bridges-win", use only the -git stuff19:18
falktxthe 64bit win bridge I think it's broken, mingw64 issue19:18
JackWinterok, and heh i was gonna use 64bit :)19:19
falktxwell, you can try it19:20
falktxmaybe it's fixed now19:20
alex-EUfalktx: i have a bit of an odd feature request, if you're interested at the moment.19:30
alex-EUfalktx: is it possible to load jackctlmmc and jack_metro as plugins in carla?19:31
falktxwhat do they do?19:32
falktxyou want a metronome?19:32
alex-EUfalktx: jack_metro is a metronome (command line app).19:32
alex-EUfalktx: If it's possible, and one that follows jack_transport.19:33
alex-EUfalktx: Jackctlmmc enable mmc transport controls for hardware devices, like midi keyboards.19:33
alex-EUfalktx: That's also a command line app.19:33
falktxah, ok19:34
falktxso having carla following mmc instead of jack transport? would that work?19:34
alex-EUfalktx: hmm, not sure. Current setup is load the app then route midi output from the hw keyboard into jackctlmmc.19:35
alex-EUfalktx: the keyboard sends stop/start/record/FF/RW with the mmc protocol.19:35
alex-EUfalktx: there used to be the ability to do this in muse/oom/and LOS, but it never worked properly. jackctlmmc does ok, but no record. (not fully implemented i assume)19:36
alex-EUfalktx: record i can do from the qwerty.19:37
falktxyeah, jack transport has no notion of record19:37
falktxbut it's only 1 patch away :)19:38
falktxthe transport has a few blocks free for new data19:38
alex-EUfalktx: mmc control is fully implemented in reaper, and works well, including record. But if can get this working reliably with LOS, then that would be ok. (Not just for me, but any user with transport controls on their midi HW devices and control surfaces)19:38
falktxalex-EU: if this is going to other apps besides carla, then it needs to be implemented as a separate tool19:39
alex-EUfalktx: jackctlmmc relies on HW input only.19:39
alex-EUfalktx: that's the nature of the protocol. It "tells" jack when to do something, but doesn't output to anything as such, like other apps.19:40
falktxisn't mmc one-way only?19:41
alex-EUfalktx: yes, that's what i meant.19:41
falktxright19:42
falktxalex-EU: so from jackctlmm you're only missing record, correct?19:42
alex-EUfalktx: and it's not going to carla as such, but if it can be loaded as if it were a pseudo plugin, without actually being a plugin, then it can be ported in the patchbay, and saved with the project.19:43
alex-EUfalktx: yes. The protocol is actually much bigger, but it's record missing for jack transport controls.19:43
falktxI'd rather not make it a plugin19:44
falktxit means giving plugins access to the host transport. this is not good19:44
alex-EUfalktx: This may also require LOS to "hear" the command to enable record, so it's a bit of work.19:44
falktxtransport should go into 1 direction only. host => plugin19:44
alex-EUfalktx: yep, appreciate that, hence my term "pseudo plugin". It's not really a plugin at all, just available as a option to save with a project.19:45
falktxmakes things a bit tricky, but it's doable19:45
alex-EUfalktx: Something like "CarlaMMC" as a separate function outside of the plugin structure?19:46
falktxcarla needs a "master" midi input19:46
falktxI'll need it for midi-learn19:46
falktxwe can use that midi input port for mmc19:46
alex-EUfalktx: right.19:46
falktxthe transport panel is already there, so gui-wise is just adding some extra widgets19:47
falktxbut the backend stuff will have to change a bit19:47
alex-EUfalktx: ok.19:47
alex-EUfalktx: Can you call the jackctlmmc app from within carla, but keep it as a separate process?19:48
alex-EUfalktx: more or less a button/command/symlink type of thing? (I don't know how to put this, sorry)19:48
falktxno need, I'll just copy the code ;)19:49
alex-EUfalktx: ok.19:49
falktxit's just translating midi messages19:49
falktxcan't be hard... I hope...19:49
alex-EUfalktx: i like your optimism. :)19:49
falktxdo you mind creating a bug report for this? (mmc control)19:50
falktxabout the metronome, eg-metro lv2 plugin already exists19:50
falktx(in lv2-examples package)19:50
alex-EUfalktx: As for a metronome, much the same. 2 settings, "sound when record only" and "sound during record and playback". Jack has no notion of -<n> so it can start from 0.19:50
alex-EUfalktx: ok, will do. I'll have a look at metro lv2.19:51
alex-EUfalktx: metro works ok, but all the time. Most of the time users only need a click when recording.  But i'll see how i can get around this.19:56
alex-EUfalktx: thanks for listening. :)19:57
falktxalways19:57
alex-EUfalktx: the intent of all this is trying to bring los in, now carla seems to support the plugins ok. With Carla and the plugins as the "central engine", i can then use other options. I'd like to start Carla and load the "central engine" first thing in the morning, and turn it off last thing at night. :)20:06
alex-EUfalktx: and once the osc stuff is done, i'll add more instances of K, and see if the separate process structure of Carla allows me to exceed the wine limit nonsense.20:07
alex-EUfalktx: So then i can load every sample lib i have, and have it all available, all the time.20:07
alex-EUfalktx: Sounds easy, doesn't it. :)20:08
falktx..yes...20:09
