Video: LED-Wiz Dances to music....

[RandyT]

It may sound strange, but only this past weekend was I able to finally get my panel completely re-done with the new GGG-49 ways (which are amazing, BTW ), 17 RGB buttons and a couple of LED-Wiz's.

It just didn't seem right not to have the lights react to the music.......so I fixed it.


Check out the video         *edit*  Video replaced after making speed improvements. No more Hamster Dance

RandyT

[loadman]

Nice LED action....

I cant say the same about your Music Taste   

[youki]

I like the music , it is really funny! 

[MYX]

Once again you are the king of arcade stupidity.  So can we download this nifty feature?
So... did you keep the blue channels solid and add R & G above certain dB levels? Or is it just like a 3 LED VU meter? Blue to Green to Red based on db? Could this be configured to use the same input and have the pulsing of the music advance a LWA from step to step? This way you could set up a LSQ and each beat would advance the LWA to the next frame.

You know it sux. I have so many ideas that I want to play with without the knowledge of how to do so. (Did download the VB by the way) Once I get done with the cab, I will be learning that (probably to trick out the cab even more).

BTW, since you are doing the 49ways and LEDWiz, what will you use for a FE? Are you using a CGA monitor? I am destpratly trying to find a solution that doesn't take a degree in rocket sience to get everything configured.

Oh, and yes, the Hamster Dance seemed sickly appropriate for some reason.

[mahuti]

Well, it's no manheim steamroller, but I guess it'll do.

[Howard_Casto]

Heh, good work.  You beat me to it though I was working on the same thing. 

But I lost my ledwiz stuff in my harddrive crash so that isn't gonna come out anytime soon anyway.

[buks]

Err Randy - you HAVE to release this ! It looks ace !

Is it a "plugin" thing for winamp or does it just run in the background ?

Cheers !

RandyT

Does that mean your new GGG 49 ways will be out soon? 

Hmmmm - must search couch for money.

[RandyT]

Err Randy - you HAVE to release this ! It looks ace !

I'll release it.  My only concern is that others may not have their panels wired like mine.  I have all RGB LED's wired R, G, and B in order starting with outputs 1, 2 and 3 and continuing like that, with Player 2 having the same configuration on it's own LED-Wiz.  The software currently assumes that every third output is the same color.  If I have to map outputs for each button, that's going to take some work yet.

I'm also tweaking the math.  I need to get some yellows in there and activate the LED levels on more of a curve to match the output of them a little better.

Also, I just replaced the video!  This time with more speed and edgier music.  Here's the link again.   >Updated Video after software improvement<

Is it a "plugin" thing for winamp or does it just run in the background ?

Does THIS answer your question?   


And MYX, I'm still working on it.  I might be picking your brain if you have some ideas as to how to go about some of these things.  I'm not a "sound" guy (in more ways than one) so I attacked it as a programmer would.  The software uses compression cutoff and biasing  to do what it does.  It seems to work pretty well and I have a few more ideas, but I'm sure there are other ways to approach the problem.

RandyT

[DrumAnBass]

Hey I like the choice of music!  I am a big fan of the Chemical Bros!

But anyway - that definately puts the Groovy in GGG! Nice work Randy!

[loadman]

Thats very cool

IMO I think thats the way it should be wired, and it's not too hard to change anyway.

Cool

[buks]

Randy,

Would it be possible to have an ini file with the led/button config in ? That way everyone can modify it to their own settings. Just a thought not  demand !!!!!

I assume the software would still light things if our is wired differently - maybe not the colours you'd want but it would still work ?

The second video seems to answer my question - it looks like your s/w sits in the background and reacts to ALL sound. Thats cool !

Buks

[jfunk]

Randy,

Now you need to jump into the 'ambient lighting' craze:

Engadget link 1
Engadget link 2

And have the colors of the buttons match the colors on the screen    Or something like that.. 

Maybe we could mount the RGB lights BEHIND the cabinet and the back of it would glow like the screen! 

Heh.

[Havok]

Awesome! That will be great for cabs that have a jukebox running, or even to just put on a stand alone jukebox!!!

<Time for Havok to sell his house so he can afford all the arcade goodies he wants for his cabinet...>

[MYX]

  I'm not a "sound" guy (in more ways than one)

LOL...Nope, I doubt if any of us are.

[RandyT]

I forgot to answer these;

I'm going to be using AtomicFE.  I'm hoping I can convince Youki to add 49-way support to it.  Maybe we can persuade him if others ask him nicely as well .

The monitor is one of the 27" RGB (CGA) monitors that I have been selling at the store.

Randy,

 

This is awesome!  Release date? 



mrC

[gonzobrian]

Yes inquiring minds want to know!

[RandyT]

As soon as I finish the LED mapping section, I'll let it go.  I added another effect and an auto level adjustment.  I will continue to add more as time permits, but it's plenty cool even as it is so I'll get it out there.  I'll need a few more days though.

RandyT

[crzywolf]

I can't wait to add this to my cab . Also what the ETA on the 49 way joysticks.

[MYX]

You should e-mail him directly about orders. Don't post it in a non related thread. 

(Unless you are reffering to the GGG flavored Joys)

[RandyT]

(Unless you are reffering to the GGG flavored Joys)

Heh, I think he is.  I had something to do on that project to make the setup a little more affordable.  I'm over a major hurdle now and in the home stretch

RandyT

[crzywolf]

Yeah , I was referring to the ggg 49 ways.

[Santoro]

Wow, I really need to get moving and install my lit buttons/LEDWiz.

Good stuff Randy.

[Lilwolf]

So, does this automatically work with any output through the systems sound system?  Or did you have to set it up to work with a specific song?

Like... for instance...

does it flash in tune with all the games in mame?

And when you have this setting, can you control other lights?  (ie, keep some lights flashing, but only the buttons which are active for the playing game)?

And as always... SWEEET!

[mr.Curmudgeon]

Any news?

I'm not sure if Randy is still going to be releasing this, but I'm working on adding this to GameEx and will be helping the Mala guys add this to their LEDWiz plugin for Mala.

It would still be nice to hear how Randy is doing this in the video.

he tells no lies.. I am a beta tester and it's starting to look cool

[headkaze]

Comon Randy, how about a bit of support for developers who are trying to write software for your hardware?

[RandyT]

There is much math involved.  It's not so simple a thing that it can be conveyed adequately without giving out documented source.  And I don't give out source to my software.

I have, in essence, developed a homebrew beat-detection method based on the compression waveforms.  Everyone will do this kind of thing a little differently, so I recommend experimentation.  You might even come up with something better than what I had.  But you can start by carving up the compression waveform data into pieces using weighted averages and act upon the results in a fashion you think will give you the effect you desire.  To be done correctly, there should also be a mechanism or two in place to try to cope with changing output levels between different songs or audio sources.  What you see in the video represents about 40 hours worth of experimentation and some pretty complex code.

There's not much I can offer you on your project in the way of assistance.  I haven't even found the time to finish my project yet 

RandyT

[loadman]

Thanks Randy

I get the impression that you are not too eager to share all the details of your code as you want the pleasure of releasing a finished version first. Fair enough too. 

But in the interest that this might increase Wiz sales (it ain't gonna hurt anyway) is it possible to give HeadKaze a couple more basic clues to save a lot of time please.

 What he is done so far is great but the brightness/colour changes are not as dynamic as yours and its is extremely frustrating and I don't want him to give up...   Anything ?

RandyT

Thanks for the support Randy! Appreciate it.

[youki]

that is completely LAME of you to not give out support to all the coders working hard to support your hardware.

Headkaze, I think he just said that he won't give his source code.  He never said he won't give  support or help for developper.

I can say  he as been really helpfull  for me  when i implemented LEDWIZ and GPWIZ support for Atomic.
He anwsered all questions i asked,  did all test i asked (and i asked a lot for the GPWIZ...)  and lot of  more.

We had huge mail exchanges.   I can not imagine  how he could do "more" support a coders.

And i really want Thanks Randy for that. 

[youki]

humm.. it seems you edited your message while i'm typing my response....

[headkaze]

Yeah I thought my response was a bit harsh, but I'll answer it anyway...

Randy has supported Atomic from day one, by donating a LEDWiz to Youki and giving you the protocol info so you can write your own dll.

He has not given the same support to any other FE. In fact he refused to give me the protocol info let alone offered me a free LEDWiz. Despite the fact that the GameEx userbase is probably bigger than the Atomic one. I guess it's because Randy has chosen your FE, but it doesn't mean we should suffer because of it.

I have written support for the LEDWiz without even owning one, thanks to loadman who incidently is a Mala user. For some strange reason the Mala and GameEx users don't see this as one big competition, we actually work together to help the scene.

So with that in mind, I have written a plugin that uses MikeQ's DLL which is more than enough for what I need, since Randy's ocx does suck big balls, and is not worth using.

Now, all I ask is that he helps get the LEDWiz going with music, but now I don't expect much of Randy since he obviously doesn't see everyone on the same playing field. Despite that I will figure out beat detection even it means learning Fast Frourier algorithms that would make your head explode. It's just a shame that Randy would rather not support the rest of the scene.

I don't agree with all that Howard says on this board, but he has some pretty good ideas about how Randy's support for developers is lacking.

[youki]

Despite the fact that the GameEx userbase is probably bigger than the Atomic one.

You can not  really know that. 

I guess it's because Randy has chosen your FE, but it doesn't mean we should suffer because of it.

Wrong.  I think he never used my Front End before doing test for me. 

So, the question is why he has been so helpfull with me and lot of others  and not with you or howard.  I don't know....   

by donating a LEDWiz to Youki

Not exactly, It is still Randy property , i will send it back to him when i will have totally completed the support of that device in Atomic.  There are still lot of cool thing with can do with it in the context of a FrontEnd! 

[headkaze]

wtf do you add a ---steaming pile of meadow muffin--- load of Carriage Returns after your post Youki? That is just weird.

Anway, well I can't prove that GameEx has a larger userbase, but It's just a feeling I have. Since it covers MCE users as well as the arcade scene and it's been reviewed on some high profile sites. I would safely say it's true but I have no way of proving it to you, but at the end of the day who cares?

As for Randy chosing your FE, I have read every LEDWiz related thread on this board and he does mention that he will be using Atomic. I could be wrong about that, but again, it's not the point why is he supporting Atomic and not the rest of us?

So, the question is why he has been so helpfull with me and lot of others  and not with you or howard.  I don't know....   

This is the mystery. Perhaps he likes people who think competition is healthy for the community? Personally I think you ideals are detremental to the scene. I think your more interested in your own ego and getting more users using Atomic than the scene as a whole. Not everyone here thinks like that. And I don't accociate myself with howard, but feel free to read the numerous posts where Randy and Howard go neck to neck. It's quite a amusing! And half the time Howard is ---smurfing--- right, and that is saying something!

[youki]

wtf do you add a ---Cleveland steamer--- load of Carriage Returns after your post Youki? That is just weird.

Sorry, i removed the carriage returns.

Since it covers MCE users as well as the arcade scene

My feeling, is that is has more user on the MCE side than in the Arcade scene. But it is just a feeling too.

I think your more interested in your own ego and getting more users using Atomic than the scene as a whole

Yes, it is my satisfaction to have more user , it motives me. You can call that ego.   But i do more on  the scene by keeping my FE totally free... then others...  that's my point of view. I know you disagree.

Headkaze, i could be wrong, but i saw a post somewhere few time ago  . Don't remember where, may be here or on GameEX forum.  Where it was written you have been paid by tom (150$ if i remember well) to develop the GameEX layout editor? Is it true?   I'm not sure to ask money for development is healthy for the community.

[headkaze]

Youki you such fool. Your wrong about that ---Cleveland steamer--- with the layout editor so stop trying to troll this thread.

Lets get back on topic, which is the LEDWiz dancing to music if you rememer.

[RandyT]

As for Randy chosing your FE, I have read every LEDWiz related thread on this board and he does mention that he will be using Atomic. I could be wrong about that, but again, it's not the point why is he supporting Atomic and not the rest of us?

I like AtomicFE and I like the way Youki supports his users.  I have seen him appear to drop what he was doing and write special programs for them at no charge because of something special they wanted to do with their system.  I have seen no other developer (other than MikeQ) who exhibits this level of selfless personal dedication to their users.  I have developed relationships with these two folks and personally like them.  And because of that, I do what I can for them (and if you saw my to do list, you might appreciate the effort that requires on my part.)

I'm trying to keep this post positive, so I will not get into all of the negatives that have affected my decisions about how to spend my already too limited time, and whom I choose to spend it on. 

On a related note, the OCX does not "suck big balls" and I spent considerable time making and documenting it.  The software in the video of the lights reacting to the music is, in fact, using it to communicate with the hardware.  The reason that no other DLL is necessary is, as you already know, because MikeQ has already provided one for all to use, free of charge.

As for my FE "selection", I don't even have a dedicated "play" machine (it's a test rig.) So when I am testing something, I need to get to it fast, and that means a mouse driven Windows interface works the best.  But if and when I do set up a small unit dedicated to "fun", it will most likely run AtomicFE, so it would be nice if it worked with my hardware

This is the mystery. Perhaps he likes people who think competition is healthy for the community? Personally I think you ideals are detremental to the scene. I think your more interested in your own ego and getting more users using Atomic than the scene as a whole. Not everyone here thinks like that. And I don't accociate myself with howard, but feel free to read the numerous posts where Randy and Howard go neck to neck. It's quite a amusing! And half the time Howard is ---smurfing--- right, and that is saying something!

I won't address the comment about Howard and I, other than to say that we are in disagreement.  Again, trying to stay positive.

There is healthy competition where everyone has the potential to gain and there is competition that is overtly detrimental.  Writing any piece of software is long and arduous work, and when you receive no compensation, the only reward is the gratitude of your user base.  How is it wrong to want to expand the user base for a piece of software you work so very hard on and receive no compensation for?  Why is is wrong or "detrimental to the scene" to feel that software which withholds desirable features or support priority from users unless they pay for it is a commercial endeavor?  Why is it wrong to have the prerogative not to directly support a competing venture one views as a commercial endeavor?  And please understand, I have nothing at all against commercial endeavors.    That is all I take with me from the comments I have seen Youki make that could be considered even remotely "competitive".

Let me just say one more time that the efforts of all those involved in adding support for GGG hardware are very much appreciated.  But I'd also like to state that I am not so naive as to believe that it is being done to benefit me.  I provide as much assistance as I can, given my time constraints, and as much as I am allowed given business constraints.  The availability of free programming tools and documentation is support of that fact.  When I am pushed for more than I am freely willing or able to give, individuals just have to realize that many things are rightfully taken into consideration when deciding whether I have the time or desire to facilitate them.

[headkaze]

Randy I appreciate your reply, but one simple thing is, since you are here right now how come you havn't replied to my two e-mails to you (15/11/2006 and 27/11/2006) in regard to writing software for your hardware. I am busting my balls trying to support hardware I don't even own and don't even care to own. I am writing this plugin to support people who want to use LEDWiz with GameEx and I hope I can help out my good friend loadman and his endevour to support Mala users.

How about a bit of support man? Why are you so closely guarding your beat detecting code, I mean comon man are you entering the karaoke business or what? Why is it so special to you? I have given loadman my "sacred" code for the LEDWiz attract mode in my LEDWiz plugin. So damn what? Who cares, I don't think my code is special, I want to help out my fellow friends in this scene. Stop being weird about things and send me your audio LEDWiz code so we can write some damn plugins to do the same and sell you some LEDWiz units at the same time. Don't you see what's going on here? We are developers writing code for nothing in our free time to support your hardware. Show some respect man. I do this for fun, not for money, I havn't made a cent out of it, so lets get real man.

If you really are this protective over your source for this, fair enough I don't want to steal your hard work. But remember this we are coding to support your hardware for free. And you being secretive about your algs for audio is only making our plugins supporting your hardware less than they could be. I don't know what to say other than that, keep shooting yourself in the foot, but it's not cool dude.

Hey I love your hardware, and I think your a top bloke, but lets be real.. give up some support good fella!

[RandyT]

I am writing this plugin to support people who want to use LEDWiz with GameEx and I hope I can help out my good friend loadman and his endevour to support Mala users.

A: customer support comes first (even before developers), and B: with all that's going on to support a new product release, I am behind on "A" and C: they were requests related not to controlling the hardware, rather related to a specialized function of a software application that I am personally working on.  Frankly, I'm perplexed as to where you are finding this feeling of entitlement to the code behind one of my projects, which is totally unrelated to a developer's ability to communicate with and to use the LED-Wiz hardware. 

Why are you so closely guarding your beat detecting code, I mean comon man are you entering the karaoke business or what? Why is it so special to you?

Aside from the difficulty of conveyance without documented source, I haven't yet decided whether the end result will be a commercial piece of software in some form, or limited to use with the LED-Wiz hardware, as is my prerogative to do.  As I said, I have already invested considerable time and resources to developing the two different pieces of software that do this kind of thing.  I fully intend on making a version available for free to LED-Wiz users, but it might not have all of the features that, say, a commercial-jukebox manufacturer might find desirable and be willing to purchase.

I do this for fun, not for money, I havn't made a cent out of it, so lets get real man.

Developing beat detection code was fun, so please feel free to have some.  Why does your development of this specialized piece of software hinge around me?  You have stated on numerous occasions that you have the basic code and ability to do it, so why the focus on my code?  I guess I don't understand your dilemma or what appears to be turning into harassment over the subject.

Hey I love your hardware, and I think your a top bloke, but lets be real.. give up some support good fella!

I appreciate the sentiment, but this is completely unrelated to support of the hardware.  This is a specialized application I am working on, not an advertised feature of the LED-Wiz. 

For fun and a performance demonstration, I recently wrote a full 4x quadrature decoding / counter application for the KeyWiz, using keyboard inputs as the source.  Are you saying that all developers who write support for keyboard input, and can potentially use a KeyWiz, are somehow entitled to this code because *I* wrote it?  Does that not border on a preposterous notion?  How is this different?

RandyT

[loadman]

Randy:
O well......   I figured I didn't hurt to ask ? Thanks anyway

Headkaze:
I think you have done pretty well considering you don't even have a Led-Wiz. I might send one of my LedWiz's soon to expedite matters. 

You can then decide if you want to buy it from me or not.

Can you believe that I have bought three of the things (don't tell my wife)? .  I gave one to Swindus and two for myself so I could do multiple Wiz testing.

So I will finish my multiple Wiz testing right after I release the beta version of the Serial Display Mala plug-in which should be by the end of the week.

So can you wait a couple of weeks?  In the meantime I can test for you from the Eastern side of Australia.
     

[headkaze]

a commercial-jukebox manufacturer might find desirable and be willing to purchase.

Fair enough Randy. I didn't realise that you were thinking of selling your software. I guess if you see something that has potention to make money then you keep it to yourself. Thanks okay.

Developing beat detection code was fun, so please feel free to have some.  Why does your development of this specialized piece of software hinge around me?  You have stated on numerous occasions that you have the basic code and ability to do it, so why the focus on my code?

The difference is my code is only using averaging and assigning a colour of the spectrum to a level of volume basically. It is very basic and the effect is in most parts of music (which is offen compressed) has levels that do not vary much so the lights will just flicker a bit. The reason I want your code is that I like your video, I don't currently have the same effect with my software and I would like to have it working the same.

What I didn't realise is that you would be so protective over your algorithms for doing this. Especially since I want to reproduce a function that will help support your hardware. To me it's a little strange, but I didn't know you were using complex beat detection algs. Anyway, I will figure it out eventually, it's just a shame your being the way you are about it. I guess once you go commercial, you see dollar signs in everything you do. But it's fair enough we all need to eat.

Oh and btw loadman, I'm not interested in owning a LEDWiz so don't worry about it. But from now on I would say it's best you talk to Randy since I don't own a LEDWiz and therefore am not a customer and not worth his time.

[headkaze]

There is much math involved.  It's not so simple a thing that it can be conveyed adequately without giving out documented source.  And I don't give out source to my software.

I have, in essence, developed a homebrew beat-detection method based on the compression waveforms.  Everyone will do this kind of thing a little differently, so I recommend experimentation.  You might even come up with something better than what I had.  But you can start by carving up the compression waveform data into pieces using weighted averages and act upon the results in a fashion you think will give you the effect you desire.  To be done correctly, there should also be a mechanism or two in place to try to cope with changing output levels between different songs or audio sources.  What you see in the video represents about 40 hours worth of experimentation and some pretty complex code.

Thanks for the brief explaination. If you can go into a little more depth that would be nice. But that is a good starting point. Can you please tell me what "compression waveforms" are? I understand the concept of compressing sound, but I'm not sure that's what you mean by that.

And when you say "carve up the data into pieces using weighted averages" do you use any type of frequency analysis or is it purely volume based?

Finally how to you assign colour to these peices of cut up sound? How do you decide after anaylsys which piece of the waveform to show the colour for?

Is there a website link that describes the method your using or the maths involved?

[Havok]

heh, well Randy has been ignoring my e-mails, so I assume that you have to be a customer to get support from him. Being a developer doesn't seem to get his attention. I don't expect him to help me out anyway, it was a last ditch effort.

It doesn't matter now anyway, I already have the code for beat detection working. I'm just trying to decide how to accociate the colour to the energy bands.

[screaming]

Beat detection software has been around for a long time, and available in a nice neat package at least as far back as WinAmp 1.0.

I'm sure you guys have done your google searches; My 1 google search for "beat detection code" brought up 789,000 hits. But have you checked out WinAmp? It's dead simple to do as a visualization plugin, and I'm sure you will get a lot of helpful advice on their dev support boards.  Or how about the source of the old open source version?  One that note, have you looked at many of the other free, open source music players that do the same thing?

But wait, and maybe Howard will know more about this, but doesn't DirectX already include support for beat detection?

Out of curiosity, with all these other (free) resources at your disposal, why is Randy's code so important?  No doubt he has used these same exact resources for his version....

[headkaze]

Yeah it has been around for a long time. So that's why I was perplexed as to why Randy wouldn't help us get the same effect in our plugins. Unless he's invented some new way of doing it, he hasn't accomplished anything that hasn't already been done. Incidently, the only matches I could find on Google for "beat-detection method based on the compression waveforms" are all patents!

I'm sure you guys have done your google searches; My 1 google search for "beat detection code" brought up 789,000 hits. But have you checked out WinAmp? It's dead simple to do as a visualization plugin, and I'm sure you will get a lot of helpful advice on their dev support boards.  Or how about the source of the old open source version?  One that note, have you looked at many of the other free, open source music players that do the same thing?

Yes, I've done my own research on Google. Beat Detection has some complex maths involved. You can take a look at some of them here. I've chosen the "Frequency selected sound energy" method about halfway down the page and using an open source FFT library for .NET called Exocortex.DSP but the most popular one is fftw.

But wait, and maybe Howard will know more about this, but doesn't DirectX already include support for beat detection?

That would be news to me!

Out of curiosity, with all these other (free) resources at your disposal, why is Randy's code so important?  No doubt he has used these same exact resources for his version....

It's not that it was important, it was just strange to me that he didn't want to help out with example code. Like you say there is plenty of info on the Net. It just would have made it easier for us to implement the technology into our plugins. But alas, I have done it myself anyway...

Attached is a screenshot of my test application.

good, I'm glad you were able to work through your problem! Good work!

Bump...

So it has been a while now Randy, you mentioned you wanted to release a completed version of beat detection, anything new?

Also, has anyone else done any beat detection for the ledwiz in the last 8 months?

I want to do a lot of things  

But I'll tell you what.  by the end of the day tomorrow, I will have a little sound toy ready to release as Alpha, WIP, No-Frills, No-support - ware

You will need an LED-Wiz Device 1 and don't even try to use it on an LED-Wiz with relays or other things you don't want actuated.

Deal  ?

Ok, I couldn't release it with support for only one device....It'll dump the same output to up to 4 LED-Wiz devices.

The thread is here.
