@ingox yeah. But the issue is the project is very complex and has many sends and receives that I would rather encapsulate in the way that I showed in my first post. Thank you for your post though, much appreciated

@1mark I see, I guess it's a matter of personal patching practice as to me that would only confuse things further.

For now you could work around it by doing it with [trigger]:

Thanks, but that would be adding more lines and boxes and the whole reason im doing this is to reduce the amount of clutter on the canvas. But thank you for the suggestion

@weightless said:

@1mark I don't think there is (but I could be wrong).
Can I ask why would that be different than using only one send/receive, since the value that is sent would always be exactly the same?

It's the same its just nice to encapsulate send/receive. For me, I'm only doing it to reduce the number of lines that this project has (which is too many!).

Hi,

Is there a way to input multiple messages into the receive symbol or send symbol text fields?

i.e next to songPos I want to input songLength.
I tried songPos, songLength and songPos;songLength and both didn't work.

Thanks

@1mark

Ok so finally fixed it @dxk well I followed what you said and I don't know if it done anything.
But I believe it was these that fixed the issue I did 1) then 2)
1)http://jackaudio.org/faq/linux_rt_config.html

2)Then the error didnt go away so I did
I select the interface -> hw:Codec (my Audio device) , save and start Jack Audio with success!

So I've done what you said and the exact same errors happen with PD. Jack works fine, my microphone works, I can use skype etc. But I don't know why PD gives me these errors
Then i got this error
JACK: unable to connect to JACK server. Is JACK running?
JACK: server returned status 17

(This happens when i run pd as sudo).

But if i run it without sudo i get
JACKerror: Cannot use real-time scheduling (RR/5)(1: Operation not permitted)
JACKerror: JackClient::AcquireSelfRealTime error

I have tried jack https://puredata.info/docs/JackRoutingMultichannelAndBrowserAudio/

Then i got this error
JACK: unable to connect to JACK server. Is JACK running?
JACK: server returned status 17

(This happens when i run pd as sudo).

But if i run it without sudo i get
JACKerror: Cannot use real-time scheduling (RR/5)(1: Operation not permitted)
JACKerror: JackClient::AcquireSelfRealTime error

Both ways i cant use jack with pd. HOWEVER jack works fine with youtube!

Hi I followed this tutorial however I keep getting this message

JACK: unable to connect to JACK server. Is JACK running?
JACK: server returned status 17

However, I selected in the settings the sound driver as jack and also I can hear sound so the server is running.

Here is the error

However after exiting the program and opening it again im getting a new issue- the solution no longer works.

I found this solution and it worked

Sorry to necro this thread, but I finally found out how to run PureData under Pulseaudio (which otherwise results with "ALSA output error (snd_pcm_open): Device or resource busy").

First of all, run:

pd -alsa -listdev

PD will start, and in the message window you'll see:

audio input devices:
1. HDA Intel PCH (hardware)
2. HDA Intel PCH (plug-in)
audio output devices:
1. HDA Intel PCH (hardware)
2. HDA Intel PCH (plug-in)
API number 1

no midi input devices found
no midi output devices found

... or something similar.

Now, let's add the pulse ALSA device, and run -listdev again:

pd -alsa -alsaadd pulse -listdev

The output is now:

audio input devices:
1. HDA Intel PCH (hardware)
2. HDA Intel PCH (plug-in)
3. pulse
audio output devices:
1. HDA Intel PCH (hardware)
2. HDA Intel PCH (plug-in)
3. pulse
API number 1

no midi input devices found
no midi output devices found

Notice, how from the original two ALSA devices, now we got three - where the third one is pulse!

Now, the only thing we want to do, is that at startup (so, via the command line), we set pd to run in ALSA mode, we add the pulse ALSA device, and then we choose the third (3) device (which is to say, pulse) as the audio output device - and the command line argument for that in pd is -audiooutdev:

pd -alsa -alsaadd pulse -audiooutdev 3 ~/Desktop/mypatch.pd

Yup, now when you enable DSP, the patch mypatch.pd should play through Pulseaudio, which means it will play (and mix) with other applications that may be playing sound at the time! You can confirm that the correct output device has been selected from the command line, if you open Media/Audio Settings... once pd starts:

As the screenshot shows, now "Output device 1" is set to "pulse", which is what we needed.

Hope this helps someone!

EDIT: I had also done changes to /etc/pulse/default.pa as per https://wiki.archlinux.org/index.php/PulseAudio#ALSA.2Fdmix_without_grabbing_hardware_device beforehand, not sure whether that makes a difference or not (in any case, trying to add dmix as a PD device and playing through it, doesn't work on my Ubuntu 14.04)

Hi,

For some reason if I have PD open then I can't hear any sound from chrome (or use my microphone). However, if I start chrome first, then I can't hear any sound coming out of PD (and I assume I can't use the microphone to input to pd either).
