Johnathon I think every video Mike Martin has made is on YouTube. Go there and search on "Casio Mike Martin", and I think you will see everything he has done. I just don't remember him doing anything, in depth, along the lines you are asking about, but once I sold my XW-P1, I quit followiing what he was doing for them.

Sounds like the display has a ribbon cable connector with an intermittent lead. Could be the battery lead, the ground lead, or one of the leads that controls brightness or contrast.

Since the static is heard in the headphones as well as the speakers, this eliminates the speaker and the speaker cut-off switch mounted inside the headphone connection. Power/battery problems would affect left and right speakers or headphones pretty much equally. This is most likely a loose or defective ribbon cable connector between two printed circuit boards. The fact that this is a recent model and was at the low edge of the middle of the line price range, deciding whether or not it is worth repairing will be a bit difficult. A rule of thumb, for US based repairs, is aound $100 just to "open up the box and take a look". Extensive diagnostics, replacement parts, and/or shipping will obviously escalate repair costs very quickly.

The CTK-11XX/12XX models do not have an "Octave Offset" feature. You can use the "Transpose" feature described on Page E-31 of the manual to transpose the keyboard down one or two semi tones to "pick-up" that note you are "missing", but you would have to realize that your keyboard would no longer be in tune with the "real" world (including the Auto-accompaniment). You also can not use "Transpose" as a work-around "Octave Offset", as it is only adjustable from -6 to +5 semi-tones.

When you record a song on the CTK-6250, it is automatically "saved" to internal user memory when the recording process is stopped. Internal user memory can store up to 5 songs. When you set up the Song Sequencer to record, you select which one of the 5 user memory slots you want the song "saved" to. You then have the option of "saving" (transfering) them from user memory to an SD Card, or using the Data Manager 6.1 software to transfer them to a computer via a USB cable, in order to free up user memory space for more songs. If you record a performance using auto-accompaniment (styles) to Track-17 (the System Track) using the "EASY REC" method described on Page E-63 of the manual, then you can use the "Recording Individual Tracks" method described on Page E-67 to add to it on Tracks 1-16, but you can not add anything directly to Track-17 (the System Track), or you will erase all previously recorded data on it.

Thanks, Rafal You DO see the file names, so at least I remembered that part correctly. When I had my trial unit, I did not work with that feature long enough to notice what you are seeing. Any way, when you have some time, try a PC sort by date and compare that to how the LK lists the files. If that does not match, try the same thing by size. For the life of me, I can not understand why the LK would sort on anything other than file name. If it sorts by date, there are utilities that can change that, so that you can control the sort order, but if it sorts by size, you are probably stuck. In my previous reply, I said the new CTK/WK models appear to play files directly from the SD Card, but as I think more about it, that is really not true. Scrolling from file to file takes forever, like the LK. I think what they are doing is loading each file into temporary internal memory, replacing the previously displayed file, so that the "scroll" time is actually the "load" time. Then, when you DO hit the START button, the song starts playing immediately, but at least the keyboard sorts and lists the files by file name.

Rafal Typical keyboard (and computer) operating systems index (list/order) files on storage devices by the ASCII Codes of the characters in the file name, beginning with the ASCII Code of the first character in the file name, so a file name beginning with a capital "A" (Decimal ASCII Code 65) would not necessarily be found next to, or even near, a file name beginning with a lower case "a" (Decimal ASCII Code 97). File names starting with all the other upper case characters would come before any file names starting with lower case characters, while numerals, then punctuation, come before all else. I have a feeling that this is what may be throwing you off in trying to figure out how the LK numbers the songs, but are you saying that you have to load songs "blind" - that you have to just enter a NUMBER and then find out, after loading, whether it is the correct song or not - that the keyboard does not show you the file (song) NAME before loading ? I had access to an LK-280, for a few days, some time ago, but I can not remember how this works. At the moment, I don't remember having this much trouble with it, and I am wondering if I even tried this. I have now rewritten this reply a half-dozen times, at least, and finally realized that I was just stating how it works on my CTK and WK boards, which "appear" to play Standard MIDI Files (SMF) directly from the SD Card. If they DO need to be loaded into temporary internal memory and played from there, that "load" operation is totally transparent to the user. You just scroll through the list of files on the display and press the START/STOP button when it shows the file (song) name you want, and it just "plays". I thought the LK's worked similar to this, at least as far as selecting the file (song) that you wanted to "load" into the selected User Song memory slot, but after your post, and after reading the LK-280 manual, I am no longer sure.

jazzsongs I must state, at the outset, that I do not own, and have no experience with, the Casio PX models, but do have considerable experience with their (electronically similar) WK "workstations" and their CTK equivalents. I noticed that your post has been out there for several days without a reply, so I will try to supply an answer, to the best of my ability, from my research of the PX-350 manual. If I have made any erroneous assumptions or statements, I certainly welcome corrections from any PX-350 owners, along with any possbile workarounds that could assist you. Normally, you would program the PC/MAC-based DAW program (in your case, the MOTU DP-8), on a track-by-track basis, with the correct MSB, LSB, and Program Change codes, from the PX-350's Tone List (Manual Appendix Pages A-1 through A-4), for proper selection of Banks and Tones on the PX-350. An alternative would be to download, or write, and install, in the DP-8 program, the equivalent of a Cakewalk (Sonar) "Instrument Definition File", which allows for "mouse click" set up of the above. Barring the above, the next choice is to use the keyboard's "Mixer" or "Performance" function to manually assign (map) the keyboard's tones to the incoming MIDI channels. Typically, these are considered "workstation" functions, and as the PX-350 is, by design, more of a hybrid digital/stage piano with limited arranger (one-man-bander) features than a "workstation", it lacks the "Mixer/Performance" functions of a true workstation. This is not to say that all digital/stage pianos lack these functions, but these particular models do. I assume from your original post, that this is what you are trying to do. If it is, and you want to use a DP-8/PX-350 set up, then you will need to program the DP-8 to transmit the correct Bank/Tone selection codes to the PX-350. Also, if that is what you are truing to do, I certainly understand your frustration. Lacking a proper "Instrument Definition File", I always find it much faster to use the hardware (keyboard) "Mixer/Performance" set up, at least in the initial stages, than mapping Tone List codes (0-127 vs 1-128) to DAW tracks, even though this foregoes the ability to make automated mid-track tone (instrument) changes from the DAW software.

Ahhhh ! Silvano ! Now I understand. Thank you for your explanation. I had assumed that you were just exporting the factory preset rhythms from your Wk-7600 to your friends CTK-5000, and that led to my uncertainty about how they would sound. Since you are a developer, I am certain that they will either sound very good, and if not, you will be able to make them sound very good. You have my utmost respect for your efforts, as I know from my own experiences (mostly failed) that what you are doing is certainly not easy or trivial. Best of luck with your endeavors ! ! ! Regards, Ted

The CTK-6250 can store up to five recorded songs in internal memory, but the total number of notes (for all songs) can not exceed approximately 12,000. So if you have five songs, whose note counts total approximately 12,000, then you can store all five songs, but if you have four songs, whose note counts total approximately 12,000, then you can only store four songs, or if you have one song, whose note count is approximately 12,000, then you can store only that one song. The internal memory location is selected before starting the recording, and saving to that location is automatic when the recording is stopped. Any previously recorded data in that locaton will be overwritten with the new data, so if all five memory locations are full, critical data should be saved to the SD Card to free up memory location(s) before recording new data. Inserting a 1/4" to 1/8" stereo headphone adapter (with no headphones connected to it) will cut off sound to the internal speakers, but you can use the FUNCTION menus for a more "professional" way to turn off the internal speakers: Press the FUNCTION button. Press the RIGHT ARROW ( > ) button to go to page 2/2 of this menu. Press the DOWN ARROW ( V ) button TWICE to go down to " General ". Press the ENTER button. The top item on this page ( " Speaker " ) should already be selected. Press the MINUS ( - ) button to change [[ on ]] to [[ oFF ]]. Press the EXIT button TWICE to return to normal play mode. Your internal speakers will now be silenced. To turn the speakers back on, repeat the above procedure, except in the 6th step, use the PLUS ( + ) button to change [[ oFF ]] to [[ on ]].

OK Silvano ! Sounds like you have everything under control. I think emailing him the rhythms is the best way to handle that part. That way he can format and load his own card. I think you could have a lot of problems doing it any other way. I did not know about the CTK-5000 not using the large SD Cards either, until I started trying to figure out why he was having problems formatting it and saw it in the manual. It really surprised me. Let me know if you have any more problems with this. I am sure your rhythms will work in the CTK-5000, I just don't know how good they will sound. At least the CTK-5000 has a Rhythm Editor so he can substitute different tones if he needs to. Best of luck ! Regards, Ted

Silvano While the CTK/WK-6XXX/7XXX models require SD Cards that are 2Gb and LARGER, the CTK-4000/5000 models require SD Cards that are 2Gb and SMALLER, so if your friend is trying to format an SD Card that is larger than 2Gb in his CTK-5000, that will not work. The CTK-4000/5000 models use the same AC7 Rhythm file format as the CTK/WK-6XXX/7XXX models. Rhythms from your WK-7600 should work on his CTK-5000, as long as you use a 2Gb SD Card (Your WK-7600 will not use smaller cards.), and put them in the MUSICDAT folder. However, if you format the SD Card in your WK-7600, it will create a hidden partition for the storage of audio files, which the CTK-5000 can not use. I do not know if that hidden partition will interfere with the SD Card's useability in the CTK-5000. If your friend formats a 2Gb SD Card in his CTK-5000, it will not have the hidden "audio file" partition, and may not work in your WK-7600. You may have to put the Rhythm files onto an SD Card and have your friend load them into his CTK-5000's User Memory from his computer with the Data Manager software, and then save them to his SD Card from there. Keep in mind that any WK-7600 Rhythm that uses Tones that are not on the CTK-5000 will need to be edited to substitute similar tones in order to sound correctly on the CTK-5000. Also, the WK-7600 reserves separate areas of User Memory for Rhythms, Tones, and Songs, but all of those go into a "common" memory area on the CTK-5000, so the number of storeable User Rhythms (max 10) may be limited on the CTK-5000, depending upon other items stored, and depending upon the average size of a WK-7600 Rhythm file compared to the average size of a CTK-5000 Rhythm file. You did not ask about Tone or Song files, but while the CTK-5000 can store its own "sampled" tones, it can not import "standard" User Tones from other models. Its "standard" Tones are limited to the factory presets, and it uses the older CM2 Song file format and can not directly import CMS Song files from the CTK/WK-6XXX/7XXX models. CMS Songs would need to be saved as SMF (.MID) files and ported to the CTK-5000 in that format, but here again, differences in tone banks may require editing.
