  1. Casio rhythm files are not WAV files. WAV files are standard Micorsoft Windows 16 bit 44.1 Khz AUDIO files. Casio Rhythm files are MIDI files, not AUDIO files. The CTK-5200 only accepts the new AC7 format Rhythm files.
  2. The keys on the Casio LK models are lit by incoming "Note-On/Note-Off" MIDI messages embedded in the MIDI file that is being played to them. So that part makes no difference what the source is, PC or tablet. What does make a difference is the physical connection (adapter, actually) required. Older iPads require the Apple Camera Connection kit, while newer iPads require the Lightning Camera Connection. Android devices require an OTG adapter. Once a proper physical connection is established, you need to ensure that the MIDI note data is on the proper incoming MIDI channels. Casio calls the MIDI channels that control keylighting the Navigate Channels. See the right hand column of Page E-60 of the LK-280 manual. On the newer LK series boards, the Navigate Channels are fully assignable, but they default to Channels 3 an 4, and believe me, it is best to leave them there. Actually, only the right Navigate Channel is assignable, while the next adjacent lower channel is automatically assigned as the left Navigate Channel. So for a default system, right hand MIDI note data must be on Channel 4, and left hand MIDI note data must be on Channel 3, in order to properly light the keys. Precious few MIDI files, downloaded from the internet, will meet these requiments, and will need to be edited with DAW/Sequencer software to place the MIDI note data on the proper channels. The worst case scenarios (most MIDI files) are MIDI files that have both left hand and right hand note data on the same channel. It needs to be separated. This is normally done by cloning the MIDI note data to both Channels 3 an 4, then use the editing software to bulk delete all notes middle C and above from Channel 3, and all notes below middle C from Channel 4. Any occasional notes that should normally span the middle C divisor can be edited back in or out, on a note-by-note basis, with the editing software. Obviously, this procedure would only be plausible for simple, basic, learning songs. It would certainly not be remotely possible with a piano concerto.
  3. Please turn to the LK-265 Specifications on Page EN-26 of the LK-265 Manual and note the 9th item down on the list, which states that the internal memory of the LK-265 is approximately 32 Kb. No matter how you want to word your argument, there ia absolutely no way you can fit a 55 Kb file into 32 Kb of memory - period. What the video you posted is showing is using ChordanaPlay to simply play a MIDI file to the LK-265's sound engine, using the LK-265 strictly as a sound module. It is not actually transferring the file into the LK-265's internal memory. This is how most users use ChordanaPlay with the LK-265, since its internal memory is so limited. They store the files on their Smart devices, and just "play" them to the LK-265. If the iPad in this video were actually "transferring" that MIDI file into the LK-265's internal memory, it would be showing the ChordanaPlay "TRANSFER" screen, which it obviously is not. I have noted much confusion about this on YouTube and many forums - users who think that "playing" a file to a device is the same as "transferring" it to the device's internal memory, when it is anything but. Many you tube posters do not help this situation any by referring to connecting external storage devices (phones, tablets, etc) as "expanding your keyboard's song memory". In a loose sense, this may be true, but in a strict technical sense, here again, it is anything but.
  4. On the PX models, the keys that you play also double as controls for various functions and features, but they are not labeled, as this would cause a cumbersome jumble of text on the face of the unit. See the diagram at the top of Page EN-27 "[Middle Right Keyboard]" for the location of the Touch Response key. It would be a good idea to familiarize yourself with this entire page, as soon as possible. Most digital piano buyers prefer their units to look more like true "spinet" pianos (ie. pieces of fine furniture) rather than typical keyboard "workstations" with face panels strewn with buttons, knobs, and sliders with all of their attendant labels.
  5. The difference in sound befween the WK-7600 and the WK-3300 is the speakers. The WK-7600 speakers use stiffer surround membranes that connect the outer edge of the speaker cone to the speaker frame. That gives a "tighter" speaker response similar to the close-field studio monitors popular today (Signs of the times!). The WK-3300 speakers have softer speaker surround membranes that allow the speaker cone to travel in and out further, especially on strong bass notes. That makes its speaker response fuller on the mid to low end frequency range, and simulates the response of boom boxes that were popular at that time. You can improve the WK-7600's sound by connecting it to an external sound system. I used my WK-7500 to drive a Technics 225 watt stereo amp that fed a pair of Sony 6 inch dual cone towers. It was superb. You can try tweaking the EQ a bit, for a little better response. My WK-7500 did not have this. As for your WK-3300 randomly changing tones, I suspect that you have a worn out switch that needs to be replaced. For what that would cost you in repairs, you could make a nice investment in a sound system for your WK-7600.
  6. That's probably your anti-virus program doing that. Whenever I tried running any of the files in this thread, Panda Dome would delete them as having viruses. Maybe they do. Maybe they really don't. I just never wanted to take the risk, so left them alone. Proceed at your own risk.
  7. Are you using a dynamic mic? Have you adjusted the MIC VOLUME control on the back of the WK-6600? If you connect the mic only, with no other connections, except power, how is the mic's level through the WK-6600's speakers? If it is OK, then I would say that your problem is with the Presonus settings, but if it is low there, then you may have a bad mic, or just need to switch brands.
  8. Memory for the 50 Preset Songs in the LK-265 has nothing to do with the User Memory for User Songs. Preset Songs are stored in permanent memory, while User Songs are stored in rewriteable memory. Total rewriteable User Memory for User Songs in the LK-265 is 32Kb. You have not come anywhere near exhausting that. The wording in the error message you are getting suggests that it is coming from the Chordanaplay App, and not the keyboard. While I can not find a limitation stated in the Chordanaplay Manual, I suspect that it has a maximum file size that it can transfer. If you are able to transfer smaller files with no problem, but can not transfer a 9 Kb file, that would be a direct indication that this is the case. If you do not have a Chodranaplay Manual, you can download a copy from here: https://web.casio.com/app/en/play/manual/ChordanaPlay-manual-en.pdf
  9. In the interest of others, who may be following this latter part of this thread, I believe that I finally understand the problem you are describing. You appear to be attempting to connect an external "typing" (QWERTY) keyboard to your laptop at the same time you connect the CTK-3400SK, but are unable to do so. If this is correct, is it because you only have one USB port on your laptop? If so, you can try using a USB Hub. The QWERTY keyboard should have no problem with this, but some music keyboards have problems working through a Hub. If you have multiple USB ports on your laptop, you should be able to connect the external QWERTY keyboard and the music keyboard at the same time. I do this occasionally with my new Windows 10 laptop with no problems. If you do have multiple USB ports on your laptop, but are still having this problem, this could be a limitation of your laptop's hardware (BIOS ?), or most likely, a flaw with your Windows 10 build, that limits its ability to generate sufficient USB Root Hubs in the Windows Device Manager to satisfy user demand. Without further information on your setup, I am afraid that this is about all I have to offer at this time.
  10. With its age, the batery contacts may be oxidized or corroded. You can clean them up without damaging the silver plating by stroking them gently with a clean standard #2 pencil eraser until they shine. Wipe the eraser from time to time with a clean cloth or paper towel to remove any residue, and keep it clean, throughout the process.
  11. The output of the audio recording on the computer should sound nearly the same as the keyboard, if the computer has a decent sound system. The keyboard has fairly high quality 4 or 5 inch speakers. If your computer has typical 2 or 3 inch computer speakers, that would explain a good part of the difference. Try listening to your recording with a good pair of headphones to see if it sounds any better. When you decide to record the keyboard on the computer, it is assumed that the computer has, at least, as high a quality sound system as the keyboard. Also check the cable to ensure it is not an "attenuator" cable.
  12. If you received a board with damaged firmware, you do not want to keep it. Whatever damaged the firmware could have damaged other things - like the memory that holds the firmware program. If ALL features of a new board do not work flawlessly, out of the box, it should be returned as defective.
  13. There is no separate volume control for the Audio-In jack. You control that with the volume control on the connected device (phone. MP3 player, tablet, etc.).
  14. Good point! I would say that your problem is not the formatting. You should be able to mount the drive, and then format it, but you are not even getting that far. You problem is the mount function. It will not mount any drive you connect, regardless of its current format. Try a factory reset (see right hand column of Page EN-9 of the manual). If that does not resolve the problem, then you most likely have a defective flash drive socket or a firmware issue, and should return the board to the seller as defective.
  15. Latency is really only an issue when you are trying to play computer based samples from your keyboard and there is a noticeable delay from the time you press the key until you here the sound. Make your connection, do your recording, and enjoy the results.
