  1. Brad is right. The results showing in Midiox are showing the results of the initial impact of the key, which is velocity, not key pressure. I do not think these Casios respond to key pressure or what is also called aftertouch. Midiox will be showing significant measurements for velocity-which based upon equal velocity from your playing-should be showing reasonably similar numbers across the key range, in all octaves, regardless of whether you are playing black or white keys, and there should be no big variation for an individual key. This is what my results are showing-surprisingly consistent and again, good job Casio. Yes, your best test would be to play another PX360 and decide for yourself. i sure hope you did not buy a display model-which could account for this discrepancy. Most people fooling around in a store display model might favor playing the white keys-and there would be more wear on the felt strips as a consequence. This would then require less velocity from the white keys than the black for similar results! This may seem a long shot, but it is possible and is just my guess. Or, the factory installer did not put the right felt strips on one or the other key assembly under the keys, and this is creating the different responses. Try pushing down firmly on a section of the black keys for as few seconds (compressing the internal felt strip a bit) and then measure the key velocity with Midiox, or by ear and see if you can detect a change. If so, this means the black key felt strips are not as worn as the white, or there is some defect in the way the white key strips were placed. It's possible although I've never played a Casio with this defect. not making any accusations, but I'm thinking this may have been a previously played floor model. .Now if only Sherlock Holmes were here to help us..............Art in the blood takes the strangest forms.
  2. I have another idea on what is wrong here. The black and white key assemblies each have their own felt bumper strips, which technically should be the same-should allow for the same amount of key-throw and shock resistance when the key travels up and down (actually the metal fulcrum arm corresponding to each key hits up and down on 2 separate felt strips above and below the fulcrum arm). If somehow the strips installed under the black keys are not identical to the white key strips, or if these strips have premature wear or defective installation, this could be the problem. You would not have the same degree of "throw"-the same momentum for all the keys. And you would not get the same physical pressure and response when the key hits the rubber sensors under the keys. Whatever it is, it should not be and needs to be corrected, IMO. If you can connect your px360 to a computer running Midiox, open the midi input window, play some keys and look at the "data 2" column. You should get pretty much identical values from the black keys to adjacent white keys. To Casio's credit-I found the velocity values very consistent across all octaves-this shows good engineering design and is certainly not always the results I see with digital pianos.
  3. OK, here is what I have observed with Midiox connected to the px350 not the 360 which I do not own. Hitting notes in various octaves I can get a range (in hex) of roughly 14 with the softest pianissimo to the 70 range at fortissimo. This is with a touch sensitivity setting of 3, the hardest setting for the px350 key response. Midiox's midi monitor shows velocity settings in the column labelled "data 2" as far as I can see. Significantly, I see no variation in these settings from black to white keys, and I thought this would be true since there is no audible difference, even with my best AKG monitor headphones. So there is a possibility of a defect in this particular px360, I'm not sure if the internal mechanism is the same as the 350. I'd like to think with a newer model than mine that it would be either identical or possibly improved in some way. Hope this helps you decide what needs to be done. I would judge such a discrepancy to be unacceptable, except for jazz or playing chopsticks (only kidding)!
  4. Shouldn't be. I play a px575 (same as px410) and the older px350 and I notice no difference in velocity response with either. Keys seem pretty dynamically balanced across all octaves white and black. Unless Casio changed the key mechanism from the 350 to 360, there should be no difference. I have not checked the channel messages with Midiox with my px350, never felt a need to but I can hear no audible differences with mine. I'll measure velocity response with Midiox and post back.
  5. You will have to disassemble it from the bottom first, look for hidden screws if you can't get it apart easily. Now look for physically obvious problems. Might be a cable connector that's popped loose. Or as cyberyogi said, a crack in a circuit board. You probably should use a good magnifying lens since even a tiny crack or broken solder joint could be the culprit and will be hard to spot with the naked eye. If you had it connected to your power supply when it dropped, check the solder joints at the power jack first, this would be my first suspect. Let us know how you progress.
  6. Good for playing swing music. Can also be used for cleaning your windows with the optional power winch attachment. And you are free to dance around the stage with the optional neck bracket, making yer setup completely mobile. yours truly, Alice in Chains and Lon Chaney
  7. Wow, glad I saw this-I've done alot of repairs including many soldering projects. Word to the wise-sloppy soldering isn't your friend, and apparently can come out of the factory like this! One tiny solder bridge created all this havoc, and fortunately didn't short this hard to replace SMT chip. Never assume everything has been put together properly! I have repaired several keyboards simply by opening them, and refitting a loose cable or connector. It happens.
  8. Which keyboard model is this? Are you using the auto-accompaniment feature or no? Fill us in with a few more details and there will be help forthcoming here.
  9. Nice work Ted-I have been too busy watching James May play his Casio on Top Gear-see my other posting in the classic Casio posts!
  10. Sorry left some info hanging here. The Allman Brothers band performed an arrangement years ago called "Jessica". The TV show "Top Gear" so popular in the UK and Europe for many years before us poor deprived US'rs ever even saw it, took a modified version of this arrangement as their title song to the show. In this episode, the celebrated James May does something very interesting using a simple Casio keyboard as a starting point, as well as an array of very interesting and expensive, rare cars-and the theme song "Jessica". Great show by the way.
  11. Season 6, episode 11-around 17 minutes in. Probably one of the more genius uses of a Casio keyboard. Apparently james may has a degree in music-and towards the end, Duane Allman gets the credit he deserves. I believe the great piano solo in this original track (not on a Casio) was the incomparable Chuck Leavell, who also arranged this, probably one of their finest arrangements, though they had many IMHO. http://www.shush.se/index.php?showlist=topgearuk
  12. So then somehow Casio is using DOS in their memory scheme? You all are apparently old enough to remember the 8-character DOS filename limitation. Add 3 more characters for the filename itself, there you go. How they derived 12 characters is beyond me. But apparently some of the internal databusses must be limited to transferring data through DOS commands or 8-bit?
  13. You mentioned something about the SD card. Could this have something to do with it? I can't tell from your post-are you accessing the SD card to switch styles around? If the SD card is inserted, errors on the card could have something to do with this. If the SD card is inserted, remove it and see if the problem goes away. and if you are using the SD card, if it is part of the problem, I'd reformat the card (save the card contents first of course) and see if that was the problem. Or try a different card. I've taken apart several Casios, all the connectors I've seen internally are locked pretty tight, but it could be. That, or even something interfering with one of the button controls. Are any of the buttons getting stuck? Sometimes a little dirt in one of the buttons could cause it to not release properly and act as if you are holding it down which could affect functions on the CTK.
  14. Did they clarify what needed to be done? Just curious since I've had to do quite a bit of this type of mod or repair on my older instruments, Casio and others. Am interested to see if it replicates some of my 'discoveries" in this realm.
