jack audio on Mac 11.15 Catalina

[EMCP]

I had JackCtl and JackPilot installed on my MBP... installed Catalina Mac OS and was greeted with the infamous crossed out symbol on JackPilot

I checked and I may be running an old tar'd binary... not sure here, but would the right move be to build and install this source here on this repository?
Thanks

[falkTX]

macOS is not supported at this point, we are focusing on GNU/Linux systems among other things.
once those are done, macOS (and Windows) support will be revisited.

[EMCP]

#144 seems to point to a beta for High Sierra... I might try my luck on that.. I cannot use Linux for Ableton Live based machines unfortunately, but thank you for the quick reply!

[kmatheussen]

Jack still runs on Catalina, people have reported, it's just the "jack pilot" program that won't start since it's 32 bit. Try to use qjackctl instead, or just start jackd manually from the command line.

[EMCP]

it'd been so long since I'd had some time to use it, so I will have to give a try again with just qjackctl and see where I get stuck without JackPilot

As I kind of recall it helped visualize the routing of the signals..

Hello, please support for 64-bit jackpilot & JACK-insert.vst 64-bit.
Jackosx the only one that keeps sync traktor and ableton, without cracks, soundflowers and blackhole the sync is lost and they have cracks.
I use high sierra, but next week I ask for the macbook 16 inc and it only supports 64 bits.
If you can update it for me and many people could use it, thank you very much and a hug.

Sorry but I think it well never happen... The JackOSX code I wrote with J.Petrantoni back in 2004 is somewhat dead.

An since @falkTX the new JACK maintener considers the JACK2 code base "ugly" and that some JACK developers had communication problems... ((-; (see https://media.ccc.de/v/sonoj2019-1902-jack-past-present-future) then motivation is lacking.. to ever, ever work on that stuff anymore.

Life is too short...

[vicente-gomez]

Any solution to send traktor virtual cable to ableton? that is in sync and without cracks

I'm using Jack for Radium, and I don't see a big point in adding support for other systems to get sound out. So there will be an alternative for jack pilot sometimes in the near future. I don't know how the state is for the source code of jack pilot though, so most likely qjackctl will get a brush up for macos instead.

[sletz]

The point is not only JackPilot, but JackRouter/CoreAudio, the virtual CoreAudio device that allows any CoreAudio application to become a JACK client. Much like JackRouter/ASIO on Windows.

Oh, right. Unfortunately I don't have any direct motivation to fix those things. I would have looked at it if I had infinite time available. I guess it's possible though? Doesn't soundflower do something like this?

[sletz]

Read back: Jackosx the only one that keeps sync traktor and ableton, without cracks, soundflowers and blackhole the sync is lost and they have cracks.

[kmatheussen]

Oh, so the cracks are there because of the way soundflower transfer audio? I thought maybe the reason for jack keeping sync was because ableton and traktor supports jack transport? (but maybe they don't support jack transport)

If traktor and ableton doesn't support jack directly, wouldn't it make sense for paying customer to ask for those two programs to support jack and jack transport? That seems like a much better solution to fix this problem. On Sun, Nov 17, 2019 at 10:54 AM Kjetil Matheussen <k.s.matheussen@gmail.com> wrote:

• so the cracks are there because of the way soundflower transfer audio? Yes. No central synchronous activation model with Soundflower...
• wouldn't it make sense for paying customer to ask for those two programs: hahahha ((-; no way... JACK on OSX runs since 2004 basically, and I don't know of any big commercial application that has ever looked a bit at this "alien stuff" coming from the open-source world...

[ahellquist]

If we don't even ask Big Commercial software companies about stuff we want/need, how are we supposed to let them know there is a need. I am a very happy user of almost everything U-he have developed and I imagine their Linux VSTs came after enough Linux users asked them about providing Linux VSTs. The same could be true about other companies.. /Anders Den sön 17 nov. 2019 kl 12:10 skrev Stéphane Letz <notifications@github.com

don't know of any big commercial application that has ever looked a bit at this "alien stuff" coming from the open-source world... Both Bitwig (probably the main competitor of ableton live) and MASCHINE (made by the same company that makes Kontakt) appear to support jack transport: https://www.youtube.com/watch?v=LFx4nTC6iz4

[kmatheussen]

I meant "Traktor", not "Kontakt". All three programs are made by native instruments though. I wouldn't be surprised if Traktor supports jack transport already.

Nice! I was not aware of that.

[kmatheussen]

Here's a version of qjackctl 0.6.0 (latest) for macox: https://github.com/kmatheussen/qjackctl_macos/archive/master.zip unzip and run the QJackCtl app. I've tested myself now, and Jack seems to run just fine on Mac 11.15 Catalina. Just use qjackctl instead of jackpilot.

[eckel]

This is great, thank you. I am using SuperCollider and in order to connect to Jack, I think I need JackRouter, which doesn't work at the moment. Any chance this could be fixed?

[KonVas]

Same here, this might be hit by the notarization function introduced on MacOS recently; are there any workarounds amidst any further updates especially for SC, that would be extremely helpful.

[hexdump0815]

@kmatheussen - do i see it right that midi (i.e. coremidi on the mac) is not supported with your qjackctl build? i just checked and there were no midi ports - the old jack pilot jackd seemed to have an "-X coremidi" option, which maybe does not exist in the mainline jack?

a lot of thanks in advance and best wishes - hexdump

[kmatheussen]

Hi @hexdump0815. That's possible, but I can't check the qjackctl build now since I don't have access to the computer. Remind me again in a couple of weeks, if you remember. I'll try to remember too.

@kmatheussen - does "close to three weeks" qualify as "in a couple of weeks" for the reminder :)

Sorry, due to the virus situation, I can't do it now. Don't know when I'll get access to that computer again.

no problem

[grzs]

Hi people,

Jackpilot abd Jack Router is not working, but qjackctl is still ok. There is a newer version available by macports and there is a replacement for the router plugin what I could compile and make work.
Here is the source: https://github.com/madhatter68/JackRouter

Hello

I would like to simple utility that listens to speaker audio / loop back and creates a .wav file,

for Mac is it possible? I read for Mac it's not possible, Please reply ASAP

[grzs]

Hi, Everything is possible :) It's not clear what you want though... Speaker audio is the output of the built-in sound card. If you want to catch an app's audio output, try BlackHole virtual audio driver for Mac. You can find description their website. This way you can redirect this audio stream to a recorder app (e.g. Audacity). Regards, grzs Ronak <notifications@github.com> ezt írta (időpont: 2020. ápr. 27., H 19:22):

Thank you so much for your answer

But we need programmatically to listens to speaker audio , We need to have BlackHole virtual audio drivers or SoundFlower, without that it's not possible?

[grzs]

What I don't understand is the 'listens to speaker audio' part. The audio flow is like this: application -> audio server (core audio, jack, blackhole) -> audio driver (core audio) -> soundcard output (speaker) -> listener's ear The only point within the system where you can redirect the sound is the audio server. I suppose you need an application which catches the flow aimed to the speaker, records it and let it go in the same time. In jack you can do it, but still need a jack client what you can choose in the app as audio output (JackBridge). Alternatively you can set it as default audio device. I found (didn't try) a software by rogueamoeba.com which looks more transparent, but it's not free. It's called audiohijack.

Hello,

I try to connect traktor 3 with Ableton. I want to play tracks in traktor and use the effects of ableton over those tracks.
I've readed the stuff above but i don't get it. What can i do to connect traktor with ableton. Thank you!

Hi,
on the Mac you can use JackBridge with 2 io channels at the moment, so it would be more convenient to use BlackHole virtual driver for this.
(After installation create an aggregate device and you can route apps' inputs/outputs to each other)

[jsl303]

I'd also like jack router to work as a sound device in Catalina!

[omarcostahamido]

is it possible to just control jackrouter from the terminal?

[grzs]

when I tested it last time there wasn't a working jackrouter available. There is JackBridge as a virtual audio interface for Mac OS but there is nothing to control. It has 2 input and 4 output channels and that's it. What do you want to achieve?

[omarcostahamido]

I want to go back to having apps show up in Jack connections window. Can you link me to the official jackbridge version? Thank you.

[chozillla]

Yeah, so JACK Audio won't simply work on the latest MacOS cause Apple. No support for 32 bit. Either downgrade or go on Windows or Linux. I can't even imagine what's gonna happen when Apple goes to ARM :(

[falkTX]

JACK works on macOS 10.15 just fine, what does not work is JackRouter, maintainers welcome.
Latest nightly-builds at https://github.com/jackaudio/jack2-releases/releases.
Official release to be announced mid October

I did not do any tests on macOS 11 yet, but assuming the same APIs are still in place, JACK will keep working.
It will take some time to support the new arm64 stuff though, depending on how we can test it.

@falkTX

Although I can confirm that qjackctl app "runs" on Catalina, I can't find any applications that work with JACK. That is, I found it no way to test audio routing at all so far.

When I open my Patchbay and try to add sockets, all I get is system. None of the CoreAudio apps such as GarageBand show up as options. What am I missing?? This is the first time I use JACK on macOS.

and here is the Status output

[falkTX]

Ardour, Bitwig, Carla, LMMS and Radium support JACK natively.

I have a "synth" plugin that can be placed into a DAW/plugin-host that allows them to talk JACK-MIDI.
But need to package it better for macOS so it works on Catalina.

[HaHeho]

I suppose all your results concern macOS 10.15 on an Intel based system? Do we have any idea about if / how Jack is going to run on Apple silicon yet?

[falkTX]

I dont have access to such hardware, nor do I know anyone that does. so it is going to be difficult.

if someone is willing to give ssh access to such a machine, it would help a lot.
in theory we can just build jack libs for both amd64 and arm64 architectures, and all works fine together.. API restrictions from Apple is the biggest concern. If they close off some APIs, JACK wont be able to work.
the iOS version of JACK2 was the first, then JackRouter... future for JACK is not bright under Apple.
