Re: [PD] rpi mrpeach lib
Hey IOhannes, Wonderful, many thanks. I had presumed (and we all know what happens to that) that pd-osc was the old objects not mrpeach so that's good news indeed as every time I've attempted to compile mrpeach for vanilla it's gone pear-shaped (yes I know - user-error!).

Re: [PD] modulating spectra of fm synth with another fm synth?
Hi, You should be able to do this sort of thing by looking up LFOs in the various tutorials / manuals (eg: http://en.flossmanuals.net/pure-data/) In fact, attached is a patch with a very simple LFO assigned to the pitch of an oscillator. It should be quite straight forward to adapt this to an FM model. Just think about which part (LFO) of the FM model you want to use for the modulation.

[PD] packOSC integer marshalling
Hi list,
It looks like the mrpeach [packOSC] external converts Pd floats to OSC integers
if the float value is equal to the float value cast to an int. From the source
code:
/* It might be an int, a float, or a string */
switch (a-a_type)
{
case A_FLOAT:
f = atom_getfloat(a);
i = atom_getint(a);
if (f == (t_float)i)
{ /* assume that if the int and float are the same, it's an int */
returnVal.type = INT_osc;
Implicitly converting floats to integers based on an arbitrary rule seems a bad
idea to me. Why bother making the conversion? Why not send floats as floats?
It's certainly going to cause problems for some clients. For example, if the
client is expecting floats on a given OSC address, it may get:
0.5 - float
1.0 - int ???
1.5 - float
Which may result in dropped values or other anomalies.
I am happy to send a code patch if people agree that this is a bug or at least
bad design...
best,
Jamie

Re: [PD] GEM question: reading from big videos
Hi João, actually those patches won't help you so much, as it aims at very short samples/videos up to about 8 seconds, depending how much memory your graphics card has. But they may give you an idea how to proceed. It's definitely not a good Idea trying to load a long HD movie in a [gemframebuffer] it might even crash gem if the memory on the card is not sufficient. but try if h.264 (compression) in pix_film runs smoothly enough (that may also depend on the OS you are on).

Re: [PD] modulating spectra of fm synth with another fm synth?
I'm not entirely sure what you want here. If you can build an FM algorithm you can replace the modulating oscillator with another FM algorithm easily enough. Or if you're talking about limiting the output spectra, you could use an FM synth as your control signal for [moog~] or a number of other filters. If you do a bit of research into the objects available you can pretty much control or process anything with anything else. What exactly did you have in mind?

Re: [PD] packOSC integer marshalling
I guess it's because all numbers in Pd are floats, but usually integer
floats are meant to be integers. But obviously it's impossible for the
code to know what the user wants, so you can also force the type by
using the [sendtyped ...( message. Probably sending all numbers as

[PD] getting Pd to run on Raspberry Pi
To Pd list, I got my Pi in the mail today (only 2 or 3 weeks after ordering it I think - they're starting to catch up with the enormous demand!) and can report what I found works and what not. I loaded the Raspian distro (the one everyone suggests) and following the blog on : http://log.liminastudio.com/programming/running-puredata-on-the-raspberry-pi just typed pi@raspberrypi ~ $ sudo bash root@raspberrypi:/home/pi# apt-get update root@raspberrypi:/home/pi# apt-get install puredata and then pd ... sort of... runs right away. I had to fool with some glitches though: 1. Pd is version 0.43-2 which doesn't yet know to try to promote itself to real-time if it's not root. (This is only fixed in 0.44 which might not make it to Raspian for quite some time.) A rather bad workaround exists: still as root (i.e., after the sudo step) type root@raspberrypi:/home/pi# chmod 4775 /usr/bin/puredata This might be a security risk (if anyone breaks into your Pi they might be able to design an exploit to get Pd to promote them to root) but I can't say I'm worried about that. (Speaking of security though, since mine is networked and ssh-enabled, I did change the password :) I'm having no trouble running Pd via ssh from another computer. The pi user is already in group audio in the Raspian distro. X windows forwarding is also turned on by default - so the only detail you have to check is whether your ssh is rinngin with -X set on the originating machine. I did notice that one can't run pd inside sudo and still get X forwarding; you have to stay as the pi user. Then about audio. I can indeed verify that the built-in analogue audio is wretched -- in two ways. First, it's not even functional (and LOUDLY non- functional :) until you se the latency to at least 40 msec (it's 25 by default in Pd on linux.) Second, it's bad anyway. To my ears the alsa play program and Pd's test-tone sound equally bad. There's a modulation that is sort of as if a sample out of every 1024 is getting dropped or doubled. You can hear the modulation change as the pitch of the test tone goes up and down. So I pulled out my cheapo USB headset from Gigaware and, with input turned off, was able to play the test tone with latency down to 10 msec, and got a clean-sounding tone out. Then, getting overconfident, I turned on audio input and although the sound came through it has hiccups and my interface froze (had to unplug the headphones to get Pd to bail :) So things are sort of working but there's still some tuning to do... I'll probably have more to report over the weekend. cheers Miller ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
