In theory you can make up to 110,592 different variances (483), but your right, with the white buttons, you'll never see em. I have found that even making jumps of 5 points higher in a given setting sometimes is hard to see a difference. If you made divisions at like every 8 points (6 points total for each color) you could make a sort of accurate color picker with 216 colors. I made a little cheet sheet for my self of number to colors. But in Randy's app, it takes for ever when trying to make any complex animations.

The issue is that led colors are not the same as colors on your monitor.  As the color value is lowered on your pc, the color approaches black.  On your ice button, it first gets dimmer and then approaches white (the color of the button).  I don't think it'll ever get to the point that you can calibrate it exactly because of this, but your major arcade button colors could be mapped out and matched with the proper windows color picker swatches.

Yes and no.  There's the transmitted "white" light created by the LED and there's the reflected white of the buttons.  In a dark room, the colors can indeed go to "black", but most will have some sort of room lighting.  This means that the darkest color the buttons will appear is equal to the amount of ambient light reflected from them. 

Calibration would probably be a little difficult and would have to be based on the response curves of the LED.  But if one were to try, it should also be based on a normal to dimly illuminated room.  Looking at the buttons in front of a east-facing bay window at 9am probably isn't going to be very useful :)

That's an interesting thought.  A user color palette rather than a mixer (or combination of the two).  I can see this being especially useful if there were an equate table that allowed the user to mix the color for the LED separately from the color of the on-screen representation.

Yeah, it would be a rough estimate. Kinda like doing photoshop on a LCD. Never looks the same on a glass monitor, but you get the general idea.

Hey Howard, I noticed you mentioned losing your LEDWiz work in your HDD crash. I found some interesting code in VB6 that will read the audio levels. Of course you have to set your Recording to Stereo Mix so it registers all sound playing through the PC. I knew you were already working towards doing this, so it should fast track things a bit so you can get the LED's working in time with audio.

I was thinking about writing a tray app to do this myself, but I don't think I can be bothered since I have no interest in adding a LEDWiz to my cab.

I appreciate it, but the now ancient dragonator jukebox program I made in the stone age had some beat detection software (basically working the same way you mentioned) so I have the source I need. 

My ledwiz stuff is on hold for a while myself.  Right now I am getting dk ready. Personally I'll probably never use my ledwiz either, unless some mame devs use the output functions to do some force-feedback stuff. I'm not big on blinkly lights, although it is cool to mess with and I do like the idea of lighting up your layout.
