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,
Bill

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.

Bill

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,
Bill

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,
Bill

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.

Bill

Sigh...thanks folks. I'll dig around here and see if I can spot what I'm doing wrong.
B

Sure can. This is one of them...

And that's why I come to this forum. Smart people live here.
Alberto, that should do exactly what I wanted.

Thanks a heap,
Bill

It would take awhile to explain exactly what I want to do with this but you have most of it right. The big challenge is that I want to get 0-360 degrees. I could use radians but it needs to be (0, 2pi) not (-pi, pi).
Hm. Looking at the wikipedia page I may have to use two formulae. X should never=0 and Y could be anything. No, make that 3 formulae since x will be <0 at times. Double hm.
Thanks for the link, I didn't think to look there.

Bill

derblub,
The funny thing is that I was the one who sent him here for the PD question. The poor guy is going around in circles.

Bill

Browsers don't like the () in the link. I had to copy it as text and paste it into the url.
Nice tune.
Bill

I think the best way to answer your questions is to direct you here: http://mtg.upf.edu/reactable/?software
Look around there and it should give you a good idea of what it's all about.

One appliction I see for the table is jamming with friends. Every marker can be assigned at least three controls for a synth. Everybody gets a handful of markers and you work things out together to make something happen. The videos linked to at the website show some pretty cool control schemes that I have no idea how to achieve, though. I could also see it being used for DJ'ing a live gig, especially tied in with video projected on a wall. Like I keep reading on the forums, "The possibilities are endless." Well, as endless as your imagination and programming ability.

Bill

>use local send and receive pairs<

That thought had actually crossed my mind but I wasn't sure about CPU load. Thinking about it again, it seems a silly concern. I'll start using them where appropriate. I'm finding that I'm a bit of a neat freak with these things.

Bill

Rats, and I was so proud of that, too. I guess that comes from being a total noob to PD and really to this kind of programming. About the closest I've come is writing macros in Excel. It's gonna take a while to learn these new commands.

Having said that, I think I see how the changes you made work and why. Now I need to put the Fon and Foff detection back in place and I should be good to go.

Thanks,
Bill

Looks like a got a bad download. I think I did move the folder but those files weren't in there. I will download it again and see what happens.

[edit] Yup. DL'd it again, extracted it to the extra folder, and everything is peachy. Or spacey, I guess.

Thanks, guys.
Bill
