Thanks!

There seems to be similar thread going on with sonsofsol.

i installed jackd, when typing this command:

pacmd load-module module-jack-source channels=2; pacmd load-module module-jack-sink channels=2;

i get the following error

Welcome to PulseAudio! Use "help" for usage information.
>>> Module load failed.
>>> Welcome to PulseAudio! Use "help" for usage information.
>>> Module load failed.

when trying to connect pd with jack i get
error: JACK: unable to connect to JACK server
JACK: jack returned status 17

How to fix this?

Also in PD, when I choose ALSA midi, not Jack, then PD appears in Jack control.
Does this mean alsa-midi is the way to connect Pd to Jack? Not by choosing "Jack" in "media"?

In Linux the JACK 'system' inputs and outputs are limited to what you physically have on your soundcard, but inputs and outputs of the software that connects to JACK are controlled by said software.

In the preferences in PD you can specify how many input and output channels you want PD to use.These channels will show up in the JACK patchbay under 'puredata'.

The DAW that I use is Ardour, and when you add tracks in the program, those channels show up in the JACK patchbay. Each track will get an input and an output that can be connected to the input or output of another program. In this case you want your outputs from puredata to connect to the inputs of the individual tracks in Ardour.

If you don't see the inputs and outputs from puredata or your DAW in the JACK patchbay then:

1. your software is not connecting to JACK...it's probably connecting directly to ALSA
   or
2. you are starting the software before you start JACK, in which the software isn't getting registered with JACK, and JACK can't manage the connections.

I'll make some screenshots for you if that will help

@Maelstorm said:

If you're on OSX, jack can be used as an insert plug-in so you can avoid the separate tracks, but you still get the latency.

which you can, depending on your host, eliminate by setting the track delay for the track with the plugin. So if the buffer is 512 sample/11.82 ms then set the delay to that and it should be spot on.

I've had the whole Jack graph latency explained to me numerous times by Stephane Letz and it still doesn't go in.....Heres what he told me...

this next part is the important bit i think...

didnt know jack also worked for windows xp?

EDIT:just downloaded jack from the website,but i get all kinds of errors when i try to unzip?

OS X 10.5.2; installed from hans' most recent two builds. (in case the newest one was buggy). I have used the build you linked to unsuccessfully. I have also tried removing the org.puredata.plist file from ~/library/preferences before installing with no success.

An update - the problem occurs whenever I open any new window - even a new patch. immediately subsequently pd-extended crashes once on load.

Another thing that confuses me is that I still get a default font missing report after installing the version that now uses monaco as the default - I am guessing the same problem may be causing pd-extended to fail to reach all these.

all my engineer friends make fun of me for being confused by crash reports, but I can't get much past the "bad access" and "kern invalid address" seeming to imply that the problem is with how pd-extended relates to mac OS X not something internal to pd-extended.

I have here's what it says for the openpanel crash:

well, it's late and I'm tired of trying to find out how to solve this the hard way. I have a weird suspicion that these are caused by the same kind of problem.

can anyone point me to a solution to these two problems on Mac OS X with Gem? I've tried with different versions of pd-extended and Gem.

1. gemwin will create a window, but it has no control - the menu bar at the top is there but there is no active buttons on it - they lack color of any sort. The window itself is stuck there. can't be moved.

2. any time I open a file via openpanel object I crash. sometimes this will crash firefox too - though randomly. sometimes crashes without crash report, or the ability to access the crashreport.

I've tried to fully uninstall all forms of pd, and pd files from the library/prefs folder but the same thing happens no matter what on both errors.

thoughts? The crash report always says thread 0 is what crashes.

a.

under preferences:
input device1: jack, channel 2
output device1: same as input.

compute audio is checked on

under the media menu:->port audio:
input device 1 : jack router 2 channels
output device 1: jack server 2 channels

under the media menu->jack
input device1: jack, channel 2
output device1: same as input. channel 2

the machine i'm using is a g5 xserve machine with a virtual output, located in a rack far away from me, behind the locked doors of an IT dept that has granted me remote desktop access. Though while it was at my place it was connected to an USB audio interface it had sound output when doing the audio/ MIDI tests or just patching an oscillator.

I'm not doing realtime audio output but recording to an mp3. my mp3 contains sounds generated from oscillators and samples, but none from the MIDI instrument i am triggering inside pd and played through simple synth.

Curiously jack display in its routing window both pd and simple synth, but also another instance of pd, named: pure_data_0, though i don't have two instances of pd running simultaneously.

I emailed jackosx and stephane letz replied back saying:

"Last time i checked the way PureData access jack, it was just broken! I mean the PD jack
code (implemented in a s_audio_jackd.c) has several problems, one of which is *never*
correctly closing the jack client. This could explain the fact you see several instances
of jack client.

I suggest to send a mail to PD developer and signaling the problem."

his comments makes me think the same problem cold be encountered using soundflower. so before i go down that patch, i'd rather finish thoroughly troubleshooting this combo, with the help of other users...

i'm looking for a free solution too. i don't think my original idea is going to work out because i don't have the time to implement it. maybe some of you have ideas for the problem i am trying to solve.

the problem is this:
i am helping a professor with some research. for his research he is doing a case study on 3 composers. he is asking them to record a narrative of there thoughts on the composition process as they compose. for this, the composers will be working an a mac studio workstation putting the composition together in logic. a second computer, a pc , running audacity will be used to record there sounds. when the composer reaches what they consider a significant change in the program, we are asking them to save their project to a new file (so we end up with a series of files showing the various stages of the composition). we would like a way, however, to map the timestamps of those files to the 'timeline' of their narrative.

here are a few solutions that are not exactly desirable:
a. do not stop the recording at all and make a note of what time the recording started. this means that you can calculate what time speech is taking place by adding the number of minutes and seconds (and hours) to the time at which the recording started. the problem with this is that it will yield very large files which are not very practical, especially considering that we have to transcribe these files.

b. have the composers start each segment of narration with a timestamp: "it is now 9:15 on tuesday...." as part of the research methodology, this creates problems with the flow of a more natural narrative of the compositional process.

c. have the composers save each segment of narration as a seperate time-stamped file. the problem here is that this takes more time, and could create a lot of files that would be very annoying to work with when it comes to transcribing.

c. my idea was to have, instead of just input from the microphone, 2 streams of audio input,one on the left channel and one on the right channel. on the left, would be the recorded narrative. on the right, would be an audio signal that encodes a time stamp. i was think of simply convert a number such as DDMMHHMM (day, month, hour, minute) into DTMF tones. these could then be translated back into a timestamp. an 8-tone dtmf sequence would be generated every 10 seconds or so. this way, as long as the narrative segment was longer than 10 seconds, it would contain a timestamp. the problem with this is that i have no way to mix such a signal with the input from the microphone.

any suggestions would be greatly appreciated. thanks.
