Hello all,
As you know, JackPilot cannot be launched anymore on modern macOS systems, and Stéphane
Letz told us he won’t work on it anymore.
I missed it so much (I never liked very much qjackcontrol on macOS) and feared that this
would be a sign that Jack would be abondonned some day on mac, so I decided to rewrite it
from scratch in Swift language.
So Jack Copilot is born,and I hope it will be useful for mac users that enjoy the use of
the Jack server on mac, even without JackRouter, which is my case on a day to day basis.
This is my very first mac app and my very first use of the Swift language, but I think the
jack developers and community gave me so much in the last years that it would be worth the
effort.
You will find it at https://gitlab.com/ericbavu/jack-copilot .
For the mac users that do not want to compile the xcode project for JackCopilot, the
repository also contains a dmg
installer<https://gitlab.com/ericbavu/jack-copilot/-/raw/master/JackCoPi… for
JackCopilot and Patchage.
Of course it is open source, and I also discussed with David Robillard (drobilla) and
compiled a working version of Patchage 1.0.2 on Catalina and newer versions for use as a
companion with Jack Copilot.
Feel free to fork, patch, and submit a pull request !
The next step for me would be to add a menubar companion so that simple actions can be
accessed more easily, and to implement a save/recall settings, but so far the app works as
expected on Catalina and Mojave.
I’m interested by testers on BigSur also, but I won’t upgrade before 6 months to this
version so if anyone is ready to tell me if it works on this version (and with Apple
Silicon also), you’re welcome !
I’m still happy with Jack 0.92b3 compiled by Stéphane Letz, so this has not been tested
with the latest releases by Falktx, but I don’t see any reason why this should not work.
Of course testing is also welcome by the community on this front.

Hi.
That was unexpected, thanks a lot!
I have a mac-mini M1 with me, I can test later to see how your version
works.
btw, is it possible to build it without xcode?
One thing worth noting is that on mac arm64 systems, if you start a
process from within a x64 application, the child process will be x64 too.
So if using qjackctl, jackpilot or something else that is built only for
intel, it will start the x64 rosetta2 emulated version of jackd.

Hi Falktx,

Great that you have a M1 mac !
btw, is it possible to build it without xcode?
Since it’s a Xcode project, I don’t think it is. But if you mean « is there a way to
compile it without having to learn how to use the Xcode GUI, the answer is yes (using
xcodebuild in terminal).
You should be able to compile the source code directly on your Mac M1 after cloning the
Jack Copilot repository, using the two following command lines :
xcodebuild -project JackCoPilot.xcodeproj -config Release -scheme JackCoPilot -archivePath
./build/JackCopilot.xcarchive archive
cp -r build/JackCopilot.xcarchive/Products/Applications/JackCoPilot.app ./build/
I’m interested though to know if the app I compiled on catalina using an Intel processor
works as expected (natively, not with Rosetta) on a M1 processor. This should, but this
has not been tested yet.
One thing worth noting is that on mac arm64 systems, if you start a process from within a
x64 application, the child process will be x64 too. So if using qjackctl, jackpilot or
something else that is built only for intel, it will start the x64 rosetta2 emulated
version of jackd.
This should not be a problem with Jack Copilot, since it should be a native arm64
application when launched on a M1 :as far as I understand the way I compiled compiled
using xcode, the Jack CoPilot app in the .dmg installer should be both runnable on x86_64
and apple silicon (natively) since it was compiled and contains the code for both
architectures, even if I compiled it on an Intel computer.
So if you launch the complile Jack Copilot on M1, it should use the native arm compiled
code, not the x64 one (unless you specify it explicitely)
Again, I’m no way a developer (just an academic researcher in acoustics), and this is my
very first experience with Swift / software development and I just tried to reproduce
JackPilot functionalities (except Jack Router of course) by looking at its screenshots and
documentation, so I hope I did not make to much « beginner » mistakes.
Keep me posted,
Eric

New subject: Jack Copilot : JackPilot revival on macOS 64 bits systems
Hi all,
I just pushed to the repository an update of Jack Copilot with some minor (but needed)
improvements :
- check at startup is jackdmp is installed where expected (at /usr/local/bin/jackdmp)
- check at startup if jackdmp is already running
- check after launch if all went well
If you cloned an hour ago with the 1.2 version, please update to 1.2.1 version (i left a
bug with my tests on jackdmp executable). It’s fixed in 1.2.1 version available both with
sources and dmg installer.
Best Regards,

Hey so, a few little reports
1. xcodebuild fails with:
error: This Copy Files build phase contains a reference to a missing
file 'AMCoreAudio.framework'. (in target 'JackCoPilot' from project
'JackCoPilot')
So something extra is needed to be installed?
Arquiving also fails, but I can just removed the CLI options for that.
There is https://github.com/dwarvesf/AMCoreAudio but no idea on what to
do regarding installing for development use.
Could it be added to your project as git submodule, so it is easier to
build the full thing?
2. patchage is x64 only. it references Jackmp.framework which does not
exist in the new jack2 installer, so it cannot run
3. JackCoPilot is seen as universal binary, but crashes right on start
with "trace trap" message.
Trying to run with rosetta/x64 mode also crashes on start, this time
with "illegal hardware instruction".

Hey Filipe,
Thanks a lot for your reports.
1. xcodebuild fails with:
error: This Copy Files build phase contains a reference to a missing file
'AMCoreAudio.framework'. (in target 'JackCoPilot' from project
'JackCoPilot')
I think this is related to the way I (badly) configured the build phases in
JackCopilot.xcodeproj.
AMCoreAudio.xcodeproj is ideed included in JackCopilot.xcodeproj so it should build as a
dependancy, but that was not the case.
It dit not cause any problem on my computer since I already compiled AMCoreAudio
separately, my bad for that. I will modify that in JackCopilot.xcodeproj so that you can
(hopefully) build it without this error.
So something extra is needed to be installed?
See my answer above.
Arquiving also fails, but I can just removed the CLI
options for that.
I do not understand what you say here.
There is https://github.com/dwarvesf/AMCoreAudio but
no idea on what to do regarding installing for development use.
Could it be added to your project as git submodule, so it is easier to build the full
thing?
AMCoreAudio comes from rnine (see README in my repository), and the full rnine AMCoreAudio
source code is already included in my git (even more than needed I think since I have put
the entire clone of rnine’s AMCoreAudio git repo).
2. patchage is x64 only. it references
Jackmp.framework which does not exist in the new jack2 installer, so it cannot run
This may be related to the fact that I compiled it using waf on my x64 computer. The fact
it references Jackmp.framework is also related to the fact that it was built using the
current jack libraries I have (I’m still happy with sletz’s 0.92b3 and I did not install
the new Jack).
As also explained in the README, Patchage can be built by getting the sources at
https://gitlab.com/drobilla/patchage/-/tree/master .
3. JackCoPilot is seen as universal binary, but
crashes right on start with "trace trap" message.
Trying to run with rosetta/x64 mode also crashes on start, this time with "illegal
hardware instruction".
Since the build did not succeeded on your computer, I assume you tried by installing
JackCopilot 1.2.1 .app using the .dmg installer ?
Would be interesting to know if it’s related to the fact it was built on my computer ?
I will try to modify the build phases configuration so that you can build it on you Mac
Mini M1.
PS : do you have access to the xcode gui to compile, or is it a headless server ?
