question about csound and pd
by ronni montoya 10 Jan '11

10 Jan '11

Hello , i been using csound inside pd lately , I use csoundapi only for synthesis inside pd and then i control everything with pd. For doing this i edit the csound code and add this line: gk1 invalue "variable_name", then i replace gk1 in the csound code wherever i want to use that values, then i can send values to that variable from pd. This works fine in most all cases, but not always. My question is why in this specific case it does not work? I using the example code of the Partikkel opcode, and i would like to control this parameters from pd: Osc2Dev and MaxSync Do anybody have an idea why this is not working? ; Select audio/midi flags here according to platform ;

partikkel and pd
by ronni montoya 10 Jan '11

10 Jan '11

hi again , I was wondering if somebody have used the partikkel opcode inside pd using csoundapi? Maybe somebody have used it and theres some example patch ? Im having problems trying to control all parameters from partikkel from pd, maybe somebody did this before and theres and example patch? thanks R.

Re: [PD] optimizing big patches

Is something like this possible? One way I can think of that you could do this would be to open each subpatch individually and then use the load meter (Media > Load Meter) to see what the cpu load for each subpatch is, though this may take a while for a lot of subpatches. You could also estimate it by looking at where most of your audio/DSP processing is happening. These are most likely to be the most cpu intensive parts of your patch. thanks R.

avoiding collapse of freeverb
by ronni montoya 09 Jan '11

09 Jan '11

hello, if i send signals with extreme amplitude to freeverb it collapses and it stop making any sound, and then it just output the word "nah" if i conect the output to a env~. For avoiding this i tried to connect a clip -1 1 object before freeverb but it doesnt work and freeverb still crashing, any idea how to avoid this crashing and why clip -1 1 doesnt work here? thanks R.

sigmund~ constant noise problem
by Shaul Tzemach 09 Jan '11

09 Jan '11

hi, I'm using sigmund~ to get sound input from microphone(with adc~), the data is controling the movement of gem objects. But it seems that the sigmund~ respond to silence as well and react in a constant change of the data. Is there a way to control this noise? Thanks, shaul

hey, not sure if it's a good or doable idea, but the mac app store is carrying free music softwares, why not have there a version of Pd? It might get lots of attention... cheers

(OT) audio (but not only) software in ubuntu maverick
by João Pais 08 Jan '11

08 Jan '11

Hi, I'm trying once more ubuntu on my thinkpad laptop, this time maverick. So far things are going well, pdext+jack+ardour (from source) are working, and the system didn't break down after some days of setup+work (which is more than last time). As I'm not up to date on ubuntu, I wanted to ask about suggestions for audio software suited for quality work. I would be looking for a sound editor, ladspa/lv2 effects (specially good EQs), etc. etc. Also any other sugestions for small aplications that make life easier (e.g. extra menus, file management, mp3/ogg players/converters, ...) are welcome. If anyone also uses a thinkpad and has a way of seting up the trackpoint, I would be interested to know.
