It definitely was as the ht-x10 had the ra-500 to save on but they scrapped it. You see the photos of the early ctk-1000 pcb even have HT-xxx printed on them. The sysex for both is likely the same but i haven't decoded the ctk-1000 sysex yet besides a global vibrato depth and getting it to handshake (but i don't know what it expects to receive after that)

The CTK-1000 with its complex sequencer but absolutely no means of saving the song to external media (and strange adapter PCB inside for its user interface) was also such a quirky thing, that was likely derived from a much more serious instrument that ended as vapourware and never reached the public.

Oh damn ! Its only a'question of how the sound is being released out of'the Piano. And not as i thought with Naming Importancy. So obviously, Thanks'Brad, i'll just focus on sound.

Grand Piano Wide : Stereo sound where the left keys tend towards the left speaker, right keys tend to sound more in the right speaker. Mellow Piano : Grand Piano with a softer mellow sound. Stage Piano : Grand with more spacial presence in the sound and with good staccato characteristics Tack Piano : Grand with metal tacks added to the hammer felts for a brighter plucky sound Octave Piano : Each note plays two octaves

Need help to decipher those mentionned Tones. Thanks

@Chas I know you already listed them, i was adding that in Japan they recycled some for entirely different product lines...and the words are different in Japan...i am very curious about what the F in FZ means...it is an open architecture sampler so it probably means flexible or versatile or some japanese word starting with F? Haha. I like your theory about the millennium synth. Even if the original M was a Japanese word, millennium synth would suit it very well for western promotions. Adding a whole extra zpi chip probably made them feel it was advanced enough to be classified as a synth. If you didn't know they had abandoned the M to mean mid sized keys, you would assume the MZ was much smaller lol. I think the real problem with the MZ is that it was a workstation, but workstation designations were already given to the 76 key versions of the CTK >>> WK. So having already used WK to mean 76 keys they couldn't mess it up. WZ-2000 would have worked tho. I guess M is just W upside down haha. Maybe it just looked cooler. HZ was obviously intended to be a synth line, by taking the consonant vowel technology and adding a filter, they felt it deserved a name "spectrum dynamic" so you don't usually invent a whole synthesis technique just to hide it in home keyboards...casio do it quite often...but no more overtly that in the HZ to HT. You could be right that the HZ was the exception...but the fact they nearly relaunched the HT series as "high technology" with the the 939 chip in the ht-x10 makes me feel they may have had much higher hopes for such designations.

As i'm looking for an Upright Mellow Piano, i just checked the Tones' list and i'm quite confused with Casio's Naming. Here are the Tones # taken from CT-X5000, so u can be awaren8f their classification #016 GrandPianoWide Is it the the biggest Grand Piano which has more than 88 keys ? #004 Melow Piano Is it an Upright Piano that was used on ''Despacito'' the'famous Pierto-Rican Song ? Or Is it just standard Upright Piano having a Mellow Effect ? #001 Stage Piano Is it a standard Upright Piano ? #010 Tack Piano I have no ideas of what that is #014 Octave Piano What is used for ? Just feel free in replying to those Piano Tones. Each small details will help me'to decipher their different tones because nowadays we dont hear the 'Original Piano Sound'' as it is being always lixed, compressed or electronized or transformed by many Brands' Style, where Casio has its own as well. Thanks

I already had those in my earlier post! 😉 @electricninja - good call on the HZ 600. Though it was pretty much just an HT3000 minus rhythms and accompaniment (but with extra user patch storage), it could be seen more as a pure "synth" compared with the rest of the HT range. Casio were likely trying to align it with their other "Z" model synths (CZ, VZ, FZ etc.) that were available around the same time. Also, thinking again about the MZ2000. It was released around the turn of the Millennium, hence the number 2000. The "M" could also be from the word "Millennium", and though it was more of an arranger (actually with a very powerful synth section among its arranger festures), the "Z" might have been linking it to older "Z" series of pro Casio instruments and synthesizers. Hence - (M)illennium Synthesi(Z)er (2000) = "MZ2000"

What Nathan Ho named IXA is actually the "triangular wave modulation" that was likely already used in classic SA-series (and possibly MT-540). The trick of reusing sine segments helps to keep the wave rom small. Yamaha OPL used different sets of sine segments (quater sine, half sine etc.) for its additional waveforms. The VL-Tone emulator is rather a simulator and the source code incomplete (some files are 0 byte). It does not seem to run actual rom code extracted from the D1867G CPU of Casio VL-1. The VL-1 rom apparently can be accessed through a test pin that outputs data on keyboard matrix lines: Pin 57 seems to be a test pin. Disconnecting its trace from 0V in VL-1 does nothing (still stays lo), but pulling it hi causes strange crashes and lights different display segments (e.g. "E"). It is hard to estimate what is going on there; possibly it just simultaneously connects logic circuits to an internal bus those should be mutually exclusive and so outputs nonsense. I e.g. once saw a rapidly running counter (like 1/10 seconds of a stopwatch) on the LCD and sometimes it seems to mix up play and calculator modes. With nothing connected, this also made the CPU think that the KO9->KI4 diode was removed, so it turned VL-1 sound off until next reset (press "P" button). After soldering a short test wire to it, often audio stays on when pulled hi, so the increased capacitance prevents some of this mess. In VL-10 I examined pin 57 closer. While pulled lo, there is plenty of data output on keyboard matrix KO pins (only KO5=lo, KO8 may be sync pulses). The height of the additional pulses apparently changes with voltage at pin 57 (which may help to distinguished them from normal matrix pulses). Pulling lo during reset displays a dot. Pressing keys does LCD segment and semi-random sound mess. Particularly {"+", "-", "×", "÷"} change data (internal addresses?) and the "rhythm" button seems to somehow advance through segments and modes. Sometimes it starts the demo (in non-VL-1 modes) or plays individual strange sounds (rarely also percussion noise variants). Pulling keyboard matrix ins hi during reset triggers various test functions. Pulling KI2 hi shows LCD test pattern "0000#0000#" with power on, or a row of dots and all math symbols when off. Test pin 57 pulls here some KI pins hi. Pulling KO1 hi turns LCD and CPU off; after power on it shows the test pattern.

SK = "Sampling Keyboard". PT = "Petite Keyboard" (seen in sales prospects) LK may be "Light Keyboard" or also "Learning Keyboard"

Thanks for your reply Brad. I just opened up this page to post an update. I have solved the problem. When programming Mainstage to "play" a sound on the external keyboard (my PXS), when entering the program number and bank number the bank number didn't make any difference. However, there is an option to enter TWO bank numbers, an MSB and an LSB. By experimenting I found that the PXS's bank number worked in one of the bank boxes - don't know if it was the MSB or the LSB cos they're not labelled! So, now I'll be able to access all the PXS's sounds and their variations - much needed for the type of shows and gigs I play for. Thanks for you help, Arthur

Version changes like this are often for manufacturing processes only. If a change for the end user is implemented, they will release a public update on their support site. Having said that, no updates of this type are expected.

This may not be ideal for your situation, but you may find a workaround after I help clarify what's happening. See, MIDI input on many Casio models has its own 16 part sound generator, including the PX-S3000. It has more channels than a typical 16 channel keyboard. This is mainly because the piano shares characteristics with arranger keyboards, like the presence of auto accompaniment and a MIDI recorder, where a larger number of MIDI channels is needed. Since MIDI is limited to 16 channels, MIDI input does not have access to the 16 part local keyboard sound generator. It accesses a 16 part dedicated MIDI sound gen. What you may be able to do is turn off local control and use the MIDI IN sound generator as the only sound gen through a MIDI out-to-in software loop. Hope this helps clarify the situation.

I bought the PX-S7000 last month and system version is 0104.

You can try changing the function of the knobs by selecting another of the preset "knob sets", but it may still interfere with the tones if the knobs are sending erratic messages. The knob sets are predefined controls that are designed to always give the user some sort of effect whenever the knobs are turned. You may find a knob set you find acceptable to live with, hopefully.

Which Privia pedal, which Privia? sounds like you need to get a new rabbit. Maybe a stuffed one would be better around your keyboards, less possible damage-unless you stuff it into the keys.

Thank you for your fast reply. Today I will try other power source, just to eliminate another factor, but I think it is unlikely. The keyboard was ordered to shipping company in Miami and from there sent to the place I am living in, I don't think seller is obliged to cover that cost and as I mentioned, it is really high, that's why I am looking for alternatives. Is there any sort of service manual? I looked with no results. "Back in the days" all the keyboards had one. On the other hand, maybe there is a way to limit the functions controlled by the knobs themselves or assigning them to a custom DSP that will change nothing/make unnoticable changes? I've never had a keyboard that advanced, so I am still learning those functions.

Unfortunately it sounds like a malfunction. I would contact your seller for assistance since it's brand new. Return and replacement may be covered, so it's worth checking. Opening the keyboard now would likely cause loss of warranty coverage. I'm not aware of any way to disable the knobs with any settings the user can adjust on the piano. Replacement may be the best option.

Hello, Recently I bought a new Casio Privia PX-S3100 BK, firmware version 0104. Unfortunately out of the box I have problems with the knobs and pitch bend wheel. They are unresponsive, and change the values assigned to them randomly. I cleaned the knobs and a wheel, factory reseted multiple times, however the results are the same. I can play for 15 minutes without being interrupted, and then suddenly my pitch and resonance goes all over the place. I really want to avoid sending it back, as I am living on an island and the delivery costs are extremely high. I tried to work around it by Freezing the Knobs, Wheel, Effect (I don't know if this does anything) in the settings, as well as changing the range of Wheel to zero. That disables the pitch bend, however I am not sure if the Filter assigned to the knob, does keep on changing or not, surely it tries, as Resonance keeps on popping on the screen. Moving the knobs or the pitch bend wheel seems to not be affecting anything at all. The rest of the functions work perfectly. Is there any other way to make sure that all the input from the knobs is ignored by the piano? I don't mind, getting rid of them at all, can I open the keyboard without losing the guarantee, to clean them internally and maybe disconnecting them permanently? Any help will be highly appreciated. Best Regards Adam

Ah ! Never really done Registration but know u can save'several features as functions, but scaring myself when confusing BackUp/Reset registry with Registration, 😂 in sense of Creating'something that will unexpectedly affect the system or the default/basic User Tones (from Ban1,2'3...with 001) after those changes. However, i know thzt Registration is quite complex somehow, but i w8uld be Happy to have my actual PianoTone in those Bank Button, in Main Board, with 4 more Buttons dediczted to other creations, Instead of torturing my eyes in remembering the exact digit# of that Tone... It would be nice if i could see a Tutorial on Registrarion, so i can be aware and try to do the best i can with, and to be very handy...coz still gettihg hard time to read/watch the Small LCD Screen ; even by changing to better Contrast, its about same, but the Visual Lackness isnt the Topic, so i'll stop there with it. Anyway, just let me'know with Registration stuff. Thanks

2 hours of a DJ playing casio or casio-adjacent tracks. Would be good if someone wrote out the playlist.

https://nathan.ho.name/posts/ixa-synthesis/ There is also some supercollider code for UPD939 emulation (IXA synth)

There is an accurate emulation of the vl-tone Vsti from 2006 with source code https://web.archive.org/web/20230201065507/https://www.polyvalens.com/vl-1/

Sounds like a CPS-60, CPS-50 or CPS-80 could also be an option but i think only the 60 has the screen.
