I'm reading data from a textfile using [metro 10].
After little logical analysing the data finally the output of [&&] is connected to (the left side of)

|
[0, 66100 1500(
|
[line~]
|
[tabread~ array2]
|
[dac~]

Array2 contains a 88200-Sample-Wav-File.

But always when I build this connection a ground-loop-like sound occurs until I cut this connection again.

Does anybody has an idea how to avoid this loop/such loops?

Hello,

Does anybody has an idea how to construct a "downsampling-device in the message domain" working without delay?

M.

Anywhere I saw a patch called "derivate". But I cannot find it again.
Has anybody an idea, where I should search for it?

The zexy

The time-object delivers hh, mm, ss, ms from left to right.

I don't succeed in adding hh mm ss into a symbol using [add2(.

Always ss mm hh (in this order) will be arranged. What should I do?

Martell

I can build makefilename-objects, but they don't work, they do nothing.

Opening the makefilename-help.pd, the objects there do what their name promises.

What could be wrong?

I'm sampling data with a joystick-Interface and process them.
For documentation the incoming datastream should be stored in textfiles.

Is there any way to build automatic packages of data (successive files) with a start-time-stamp as filename in PD?

I want to use "netsend" to transfer data to another application.

When I connect the incoming data [joystick-floats) with the [send $1( - Object the following error occurs:

error: gatom: no method for 'send'

How can I transmit a stream of floats via netsend?

Martell

I'am sampling data (stream of floats, 20 Hz-rate) with an other AD-application. This app sends strings via tcp/ip to PD and sometimes PD receives this data (using netreceive 8080). But in most cases PD does not start progressing the received data. Instead of "EOF on socket XYZ" is prompted.

What should I try to remedy this.

Martell

Does anybody know how to add strings and atoms without seperation by
a single space when composing complex messages?

Martell

Does anybody know, how to send a stream of numbers via tcp?

The netreceive object can capture numbers separated by a semicolon.

I could imagine that there is already anywhere a pd-looping-object accepting
2 arguments:

The both borders of the "endlessloop"-field in the sustain-area for example in an organpipe sample. And the "endlessloop" should end with the note-off signal from the midi-keyboard.

Does anybody knows what I mean or where I should search for something similar?
M.

I remember having seen a monophonic synthesizer in my
Pd version 0.39.3-extended.

Are there anywhere patches to use PD as a polyphonic synthesizer playable
with a midi keyboard?

Martell

I use pd under windows. For crossfading I tried to load a list of sample filenames from a textfile "wavs.txt".

The following error-message occured:

opening:: symbol C:/ort/wavs.txt
soundfile_info_read-error: C:/ort/1.wav has a format-chunk not equal to 16
caching: 69 C:/ort/1.wav 1000 10000 0 0 132300

The "1.wav" was created with the Windows Audio-Recorder as a stereo-44100kHz-wav. How can I solve the problem? What does the message tell to me?

Thanks for help,
Martell.

How do you want [&&] to trigger the [line~]?

You are right: The output of my[&&] was too "noisy":-(

Now I use

[change]
|
[sel 1]

in combination with a better logic in front of the [&&] and now this happens what I expect.

Exchanging [metro 10] by [metro 100] lowered the pitch of the disturbing "loop", so I assumed the metro-frequency could be responsible for this interference:-(

Thanks.

etap.txt contains measured data, 100 Hz samplng frequency

http://www.pdpatchrepo.info/hurleur/read_write_tabread~.pd

I found the reason:

At the outlet of the [&&] object sometimes a "1" occurs - as expected.
But 100 times a second the [metro 10] beat triggers the tabread~-Generator through this object.

This is/was the reason for the heared "feedback". Actually it is not a feedback at all.

But how to prevent this [metro 10] - beat ? The input textfile contains data sampled with 100 Hz that should be replayed in real time...

M.

I tried saturnos variations, but the feedback loop did not disappear.

On mouseclick at [0, 66100 1500( the generator works well.
The reason of the feedback is outside of the tabread~-Generator.
So a HP-filter too cannot solve the problem....

M.

I tried [downsample] an what happend?

It worked:-)

Thank you sunji.
