Hi,

What do you think about fiducials .. you mean the Fiducials reconized by the software reactivision .. (Reactable software) ..?

i am having trouble filtering which fiducial controls which function in pd, i'm trying to create a pitch control similar to a turntable pitch, but every fiducial is acting on this can anyone help?

This is my first post I have been wondering around here for awhile. My first tech project was in multitouch but I'm a musician by nature. I have wanted to do a key-taur VJ battle for awhile now and I'm starting to get it going. The key-taur will only have 5 keys but it will also have a pick pad that uses a fiducial tracker AKA Reactavision to further modulate samples and video. I have attached my first version of the patch and want to know what other people think and how I might be able to improve it.

I have fiducial tracking manipulating the size of the rectangle the video is textured on right now. It will definetly not be that way in the end.

We plan to wire up anrduino to drive the buttons and led's on the key-taur. I imagine I will need some help when I get to that part. We want to have a working version of the key-taur in about two months. Also we are thinking about adding an accelerometer for even more modulation capabilities. We plan to make two and our theme is analog versus digital even thought we are not taking that to the maxis. The analog key-taur will be corded but we are trying to make the digital one wireless.

So print out some fiducials if you don' have a set and give this thing a try.

Hi! Thanks to all the nice people here who have done such great work that got me interested in PureData (and by extension Arduino) in the first place!!!!!

I finally got my Arduino and PureData/GEM communicating nicely with PDuino! Wonderful!

Here's a video:

Hooray!

Now on to my problem. I am using Pd version 0.40.3-extended on an Intel MacBook Pro running OSX 10.5.4.

When I open up PD this is the messages I get:

Can anyone tell me why GEM and xsample load in but all the other libraries do not?

Also, where the heck do I get the OpenSoundControl object for PD??? I'm a total noob when it comes to compiling from source code, is there an easier way?

Thanks so much for anyone's help

ok are you on Intel mac? then you need the objects compiled for intel.. I don't know why that webpage hasn't been updated yet.

You can get them here: http://puredata.hurleur.com/sujet-1280-fftease-39 (scroll to bottom of post for attachment)

The help files are still relevant so put them where instructed..

If you are a beginner go through the Help browser I01 - I10 to get the basics..... a word of warning though, understanding fft can be a bit of a headfu*k at first and requires understanding the basics of dsp (ie, simple maths and signal flow) Even some of the seasoned pros on this board struggle with the numbers!

Try reading this for a detailed tutorial to understand what actually happens when audio is sent into the frequency domain: http://footils.org/cms/show/60

If you find it too much to take in, you could try the fftease library, which has a collection of spectral objects that pretty much cover all areas that you'll need...you can find this here: http://www.sarc.qub.ac.uk/~elyon/LyonSoftware/MaxMSP/FFTease/

have fun

Hi

Unless you really want to understand the theory behind the phase vocoder (which makes my temples ache even now), I would suggest giving the fftease lib a go. For intel compatible on osx, just search for fftease on this forum and theres a link to where someone built them from source code. As to why they're not on the main page i know not.

In fact it has an object called [pvharm~] which will do exactly what you want. Just play around with the window settings and your good to go

nice stuff thanks!
anyway i did not already manage to performe what i want
looks loke a holly grail i'll not reach that soon

The easy way to do it is to download and install fftease library

Am I allowed to cheat?

ps. for universal binaries of this lib, just do a search on this forum and theres alink to download the zip

Hello

So, I've been successful in running Reactivison with PD and can control loops in Ableton Live with fiducials using my built in iSight on my Intel Macbook.

My problem is getting that information shared with the visual patch (visual_patch.pd) to display the position of the fiducials in GEM. I open the patch and the GEM window is rendered with the small white circle in the middle, but no recognition of the fiducials, even though I know the TUIO patch is getting the information from Reactivision.

I am running version 0.39.3-extended. I suspect it's a problem with pmpd but I can't get PD to run with pmpd. I keep getting these types of errors:

I've tried moving the stuff from the extras folder around as mentioned in a previous post but no success.

Can somebody please help me along with this? I am lost.

All the best.
