Hi all,
I’m having problems connecting Sc to Ableton 9 using Jack2.
I guess this is not because of something wrong in the code…
Windows 7 home premium
SC 3.9.3
ASIO4ALL v2
Jack 2 64 bit
Ableton Live 9
Maybe I missing something in the installation process.
Would be great if someone could tell me what I’m doing wrong, or just an hint.
Start Jack PortAudio
Make sure that the Jack Audio Server is running by checking the command prompt window
it’s everithing ok, it seems.
With the Jack Audio Server started, the JackRouter ASIO driver will be available for your ASIO supported applications.
Within your audio application, select JackRouter as the audio device.
Server.killAll; // kill the ghosts
o = Server.local.options;
o.numOutputBusChannels.postln;
o.numOutputBusChannels = 100; // The next time it boots, this will take effect
o.device =“JackRouter”; // use a specific soundcard
o.memSize_(2.pow(20));
s.reboot;
s.meter;
s.plotTree;
a={Impulse.ar(8)}.play;
a.free;

Why ?
Booting with:

Is that correct ??
then I lunch Live 9, I can’t see any JackRouter , but I can choose ASIO
SC: “JackRouter ASIO” is not included in the list of available devices.
Live: “JackRouter ASIO” is not available in the driver menu
The Occam’s Razor conclusion is: JackRouter ASIO is not actually becoming available only by starting the JACK server.
So I think you need to make sure that JACK is truly functioning properly first. Maybe some documentation somewhere says “With the Jack Audio Server started, the JackRouter ASIO driver will be available for your ASIO supported applications” but it seems pretty clear to me that this is not actually happening on your machine.
I thought that, with this version of Jack2 I didn’t have to register the .dll
the guide said:
The Jack v 1.9.8/64bits/JackRouter.dll still has to be registered “manually” with regsvr32 - so please try the following command to register the 64-bit JackRouter:
but … after a few seconds
SC_PortAudioDriver: PortAudio failed at Pa_OpenStream with error: ‘Unanticipated host error’
could not initialize audio.
Open error: is JACK server running?
RESULT = 1
and Jack says:

if any of you could tell me what’s going on would be great,
I searched for : JackEngine::ClientCloseAux wait error ref = 2
but with no luck.
thanks and sorry for this silly and tedious questions.
I’m afraid not many SC users have much experience with JACK in Windows.
So, what is known right now is that registering the DLL got you to a point where “ASIO : JackRouter” shows up in the list of devices, but PortAudio isn’t able to do anything with that.
The message “Driver is not running” in the JACK console output is suspicious, but I’m not sure of the sequence of events so I don’t want to speculate.
One thing that is not known is: Can you use JackRouter with other audio software on the same machine (e.g. Live)?
If JackRouter works in Live but fails in SC, then it’s a SuperCollider problem.
If JackRouter doesn’t work in any audio software on the machine (which was the case initially but may or may not be the case now), then it’s a JACK configuration problem and it would be better to follow up with the JACK community.
