You answered your own question in a way. For the wagon wheel case you need to dramatically increase the sampling rate (shutter speed) so that aliasing is mitigated, then blend those frames in a low pass manner so that any change in the scene can be tracked with a lower speed shutter without introducing false frequency information. The wagon wheel spokes would then look like a blur, which is how the eye perceives them as it has no shutter or sharp sampling behavior. Any time there is false frequency content there is aliasing going on. This kind of aliasing is actually heterodyning, a non-linear mixing of the multiplexed LED or wagon wheel rate which is close to the shutter speed, producing sum and difference frequencies, and what we see the difference.

Moire patterns are aliasing in static 2D: there was high frequency content in the original picture that was above the spatial sampling limit (detail that couldn't "fit" in the newly shrunken pixel environment). So before subsampling we first need to remove that high frequency content by sufficiently blurring the picture.

Sorry for the OT, I've been buried in heterodyning and sampling methods for the last couple of years!

OK, you can fix it in post. Bazinga!

Ha ha!

Please, take it as a compliment! Great to have two intelligent guys with perspicacious insight on topics most of us (or just me) don't understand.

RD800 looks like it will be back at GC on 7/31/2014:

It's back at Kraft Music, and I just today ordered one to be delivered. Now to work on how to explain this to the wife....

Congratulations Pete! It's an exceptional stage piano as you will discover. Be sure to take the time to learn all it has to offer. Then play it for the wife and you will have no worries (assuming you play piano )

And I can sense that flashing in some car LED tail lights, and it drives me nuts. MB started and was the worst. I don't notice in the newer cars, thankfully must have raised the frequency.

Yippee! I now have my RD 800, have set it up, and have played it!

First impressions:

• Compared to my Casio Privia PX-3, this sucker is heavy.
• But having said that, its action is SO much better. My god it feels wonderful to the touch!
• And its tones are orders of magnitude better! God I love this thing!
• It's going to take a while to get familiar with all the tones that are available, and even more to figure out just when I will want to use them.
• The buttons, menus, and such seem fairly straightforward to use, although admittedly, I've only used the more primitive functions so far.
• And yes, it records wav files and records them nicely to a USB thumb drive. This can help me store my quick sketch ideas while song-writing.
• Although it doesn't look like I can over-dub a previous recording. Anyone, please correct me if this is wrong.
• I like the live set functionality, and that I can store live sets to USB. This looks to be a nice way to get everything just so before performing. It would be best if I could change settings, swap live set locations and such via my Windows computer, but if it's possible, I don't know how to do it just yet.
• ...And I'm not doing well at sharing images on this site just yet!

Congrats Pete!

Now, time to ditch that horrible X-stand... ;p

Congratulations Pete! For the record, Pete is NOT my roommate ... and yes James, time to ditch the horrible X-stand for both of us!

James,
LOL I thought the same thing.

Nice setup! (otherwise) Love the speaker set up. It looks like you've stuck them on a second tier? (or is that a shelf anchored on the wall?) Anyway, she looks beautiful. Also love the wall color!

Marko,
Wow, that's awesome! great coincidences

Now all you need is the picture from "The Chronicles of Narnia: The Voyage of the Dawn Treader."

In the interests of symmetry, I guess it's time for me to find me a picture of a schooner sailing ship!

So, is there any word on another batch of RD 800s or an RD 800 mark II with a more organic and elegant solution to the power cord problem? I really like the look of this board, but I have no intention of buying one with a power cable permanently attached, and nor do I wish to undo the modification as it stands.

sixfootpianist,
There have been no announcements from Roland that I'm aware of. If something like that is coming, I doubt that Jay can chime in on it until there's something official from Roland about it. So when, or even if such an update is coming, well that's anybody's guess. It's a really great board though. Have you tried it? If not I'd suggest you give it try if you can before making a final decision. You might just fall in love with it and decide that you want it even with that limitation.

So much time, money and hassle could be saved if manufacturers would just engage with a bunch of real performing musicians before they commit to production.

Plain and simple - best post of 2014.
