I am trying to record and edit some very short samples for use in PD. System is running WinXP, AMD XP3200, 1 Gig ram just to give you a baseline. Soundcard is soundblaster Audigy2 ZS. I have used the Creative Wavestudio, and Audio Studio 7 (I don't remember who makes it). No matter what I use I end up with wave files that won't play in either PD or Media Player 11. According to the files themselves they are 44100, 16-bit mono samples but all I get (if anything) in PD is click. I used arrays and tabwrite~ to try and see what was there and saw a wave shape, but...

Any ideas would be appreciated.
Thanks,
Bill

I am rapidly realizing I should have paid more attention in my Triganometry and Geometry classes.

I am using zexy's [cart2pol] to convert x,y coordinates to polar coordinates and [rad2deg] to convert the angular data to degrees. The problem I am having is that when it converts the Phi it makes half the circle + and the other half -. Is there any "simple" way to convert x,y data so that the angle amount continues positive until it hits 360 degrees? I think it would make the rest of my computations simpler.

Thanks,

I'm pretty stoked about this. With all the hints I've picked up here I managed to make setting up a fiducial marker for the reacTIVision software a snap in PD. I made it a sub-patch/abstraction sort of thing I think. Sorry for the jumble there, I'm still not sure about what things are called.

To use it, dump this patch in your extras folder (or in the path somewhere) and when you want to track a marker, make an [rct_marker x] object in your patch with X representing which fiducial you want to track. The object will output, in order, Added, Removed, X-axis, Y-axis, and Angle. Added and Removed are bangs and the other three are floats.

Okay. I'm calm now. I love succeeding in these little tasks I set for myself.

PS: It just passed the "acid test", too. It tracked three markers at the same time with a camera set-up, not just the simulator. That was one of my other concerns.

This patch is secifically designed to work with the reactivision software found at http://mtg.upf.edu/reactable/?software

Side Note: I was trying to build a standalone "sender unit" so this could be tested without all that other stuff but I guess I'm not that smart, yet. I'll keep working on it, though, 'cause it might be handy to have.

Anyway. This patch got a bit busy there toward the end. Is there a 'cleaner' or simpler way to accomplish the same effect?

Thanks,
Bill

I have a [pack] that packs three floats. When I run it through [pipe] the only thing left is the first float. I checked it with a super simple patch and it always does it.

Now how do I fix that? I need to delay that packed info going into a [spigot] to avoid false triggering my output. I looked at trigger and couldn't see how to use it in this instance.

Thanks,

xYzee looks and sounds like a cool patch. Unfortunately when I try to use it I get at least two errors. The [scale_map] object in lead_seq.pd and the [set_scale] object in xyz_main.pd both show as broken objects, meaning neither have solid lines around them. There were more but I finally figured out I needed to install Cyclone. Is there another package I need to install to get this to work?
Thanks,

Here's another look at a reactable in action in a live setting. Originally posted on the reactivision forum at sourceforge.

What I ended up doing was figuring out which one was the "right" one deleting all the others. The right one is the one in the examples folder. I think the others are in the extras and some of the sub-folders.
Hope that helps,
Bill

Alain,
I think there is. Check the tutorials for Gem in your \pd\doc\manuals\Gem folder.
You can also tell Gem what order you want it to draw objects. That should be in the manual, as well.
Bill

tiamat,
When I ran into that in the past I found where the patch was in the doc folder and copied it into the extra folder. Alberto's answer is the more correct way to do it, though.
