Re: [PD] Pd freezing on startup in ubuntu dapper
I booted up a LiveCD of Dynebolic v1.4.1 which has Pd on it. Just as with my ubuntu machine, trying to run Pd froze the machine utterly, completely. So my guess is it has something to do with the driver for this particular sound card, the Alsa library, and Pd. I'm guessing Pd must load in the libraries for alsa and/or do some sort of check of the audio hardware initially, regardless of the flags set on the command line, and this must be what is crashing it. I'm not sure what is unique about Pd as opposed to all of the other audio apps I have tried on this machine, but apparently there's something because no other audio apps are crashing. I'm also not sure how it is that others are apparently running this same M-audio Delta 1010LT card w/ Pd with no problems? Can somebody confirm this? I see the card referenced in the official Pd docs for installation in Linux, so I'm assuming this card apparently worked with Pd somehow, at least at one time. I thought of trying the same card w/ Pd in another machine, but I'm not even sure where I would go w/ these results... -John John Harrison wrote: Yes everything works with jack...except Pd. pd -jack still freezes the system utterly, completely.

Convolution can be defined in two completely equivalent ways: one as

Almost all of the time, the time-domain representation is taught first.
This might be especially important as the frequency-domain only becomes

Right.
So if your block size was four and you had one FFT block that was:
0,1,0,1 And another that was: 0,0,0,1 The convolved real sound block

Yes, supposing each of those values is a complex number. But that's
because AND is a special case of multiplication, because:
0*0 = 0
0*1 = 0
1*0 = 0
1*1 = 1
so * over {0,1} is exactly AND.

[PD] Using csoundapi~
Hi all, I was checking out the csoundapi~ external, and was wondering if there was any updates to the help files. Basically, I got a copy of the external from the Csound5 distribution (there was no help file with it, contrary to what is in the manual), and the help file that I did find was from the 4.2xxx version. There seems to be a difference from what that version expects. The 'csd' file linked in the pd-instance doesn't seem to recognize that it is a stereo patch, and only creates a single audio channel. I did notice that when I changed it to [csoundapi~ 2 test.csd] that it created a stereo object. Anyway, I have not had a chance to test weather or not the other messages work with the csoundapi~ object, as I can't get the orchestra file to load. Anyone got any ideas?

[PD] japanese text strangeness
Hi, I have been trying to get an extended character set correctly mapped into PD from external text files. T. Mayer pointed out that PD (at least on osx) use UTF-8 format. So saving all my text files as UTF-8 lets them load into PD with the characters correctly mapped. In this way I am also able to get Japanese characters correctly mapped into PD. So now I want to bring them into Gem - the textextruded object. I am using the Hiragino OTF that ships with OSX. The font loads fine, but the Japanese characters will not display - reference the correct characters. Just a buch of very wrongly placed latin symbols and accents. Im feeding them straight from a symbol object so I can see its the right characters. Is there a limitation to the [textextruded] object? Or could this be the font? Anyone know a fix here?

Or you could send data through the serial port with different ratios of on and off bits, but you will only get 8 different levels. I think you need to put a serial dac there. It's possible to clock serial data into a dac using just the handshaking lines -- one serves as a clock and the other data.

Then I changed the permissions on the file:

Then I ran the following command:
$ sudo update-rc.d -f pd_start start 99 2 3 4 5 .
Where:
- start is the argument given to the script (start,

- 99 is the start order of the script (1 = first one,
99= last one)
- 2 3 4 5 are the runlevels to start

After hitting enter I get this:
Adding system startup for /etc/init.d/pd_start ...
/etc/rc2.d/S99pd_start - ../init.d/pd_start
/etc/rc3.d/S99pd_start - ../init.d/pd_start
/etc/rc4.d/S99pd_start - ../init.d/pd_start
/etc/rc5.d/S99pd_start - ../init.d/pd_start
Then I do this to stop my script at shutdown:
$ sudo update-rc.d -f pd_start reboot 90 0 6 .
It is important NOT to forget the . period at the
end! After hitting enter I get this:
usage: update-rc.d [-n] [-f] basename remove
update-rc.d [-n] basename defaults [NN | sNN
kNN]
update-rc.d [-n] basename start|stop NN
runlvl [runlvl] [...] .
-n: not really
-f: force
Then I restart the server to see if it works!
$ sudo shutdown -r now
AND IT DOES!!!
To know which runlevel you are running, simply type
$ runlevel
