I am looking for the administrators of the pdpedia wiki project. I thought I'd check here before I hit the list.

Could someone point me toward a list of all the libraries that ship with pd-extended. I think I may have messed up my install and want to make sure I'm not missing anything (without reinstalling if possible.)

I am looking for a way to have two GEM outputs that would show the same thing.
I am doing a show and I need to face away from the projector. I'm using windows, So I extended the desktop and I have one GEM output on the projected half of the desktop and my controls on the other. Is there any way to have another output showing the same thing that I can put next to my controls?

Pardon me if this is covered elsewhere I have been looking and have had no luck.

So i have built a patch that reads in sound and renders it as image via GEM.
I am triggering (long) GEM render chains (more accurately lots of short ones, one after the other.) using metro what I need to do is control the value (speed) of the metro. I have a controller that sends new specific values on button presses.

[91.55(
|
[100)

[metro]

What I want to be able to do is increment or decrement the value by some small amount like 1 or 0.01 triggered by a button press (one button for up and one for down)
I tried taking the counter mechanics from the help documentation and adapting them to little success. Is there some pre-existing atom or standard method that I am over looking.

[bonk~] looks for percussive attacks in a sound source.

I would recomend giving method 1 (analysis in PD) a shot.
I originally thought you were analyzing outside sound.

Since the sounds are coming from PD getting good control data shouldn't be hard.

Once you get data you like OSCing it out of PD is pretty easy. (I'm assuming its similarly easy on the vvvv side, I not familiar with vvvv)

OSC is only for control data not signal data. It is designed to be an awesome replacement for MIDI. Without knowing more (your OS, your background, what exactly you want to do) I can only give general suggestions.

One option might be to do the audio analysis in PD and then just send control numbers to vvvv via OSC.

If you need to deal directly with the audio in vvvv you will most likely need to use something like JACK which should allow you to put sound where ever you need it.

Of course if you can get the sound into vvvv directly you might not need PD at all.

[bonk] and [fiddle] can be tricky depending on your sound source. Depending on what you need to measure [env~] (to track volume) can be very useful especially with [moses] to watch thresholds. But if bonk works use it. Its simpler to use and in many cases cheaper.

[beat] [rhythm] may be useful after the initial analysis.

Though a keyboard and mouse would be much easier; If the custom controller sent MIDI data it is fairly easy to read MIDI in and it is already in numerical format which could help to simplify the process.

Like obi pointed out this sounds like a pretty big project but there are some very cool procedural soundmaking options inside PD which could help simplify things.

I think you will need to look at the [pack] [line~] and [output~] object. these will allow you to do basic crescendos. If you are looking to control volume based on a second audio source [env~] is a place to start.
