Yes. Touch and hold the GRAND PIANO button and the six keys from F#7 to B7, light to heavy. They are the top keys below the upper C. If you look in the manual, there is a diagram of the keys and all the functions available to you including these.

Not true. I've been a Mac user forever and a Casio user for a long time too. They just work for me. I've never installed a driver for a Casio. Can you provide links to the cables you are using and describe where you are connecting them?

The CDP-100 power adapter might work in the CDP-S350, but I can't be certain. The CDP-100 is a few years old and it's been a while since I've seen one nor looked at the power adapter.

The Casio CDP-S350 should have come with a power adapter in the box. Contact the dealer and tell them you didn't get it. The CDP-100 used the AD12M3 12V power adapter. The CDP-S350 uses the ADA12150 power adapter, as do most current Casio models such as the CDP-S series, PX-S series, CDP-120, 130, 220, and 230, PX-3, PX-S5, PX-330, 350, 360, 560, 730/735, 750, 760, and some other models.

You can find toilet paper? You lucky dog.

How cheap is "very cheap"? I don't advocate throwing stuff out, but depending on the models available where you are, the CDP-100 has been replaced several times since it shipped. The current model(s) are the CDP-S series and most consider the CDP-S100 much better than the CDP-100. The CDP-S150 is even better than the CDP-S100. The problems with that CDP-100 you're looking at might be as simple as a loose connector. Or, something might be significantly damaged such as the motherboard or "wiring" (more likely traces) on the keyboard PC board itself. Or, it could just need a good cleaning.

Logic is ridiculously powerful in its MIDI capabilities. You can really geek out with it. Even though I cannot say with 100% certainty of having tried what you need to do with it myself, I'd be really surprised if it couldn't do what you are seeking. Best of all, there's a 90 day free trial. See if you can make it work (as well as adjust to the advanced capabilities over GarageBand) before you spend your money. https://www.apple.com/logic-pro/garageband-to-logic/

Usually if it's a single note it's dirty key contacts. That fix can be relatively easy. With multiple notes, I'm not so sure. It could be a loose connection so the sound generator only sees one sensor. Still, I'd try cleaning it with compressed air and see if that helps. Maybe it's less notes than you think.

A web search led me to the Casio euro site, where they use the term high grade for some current Casio products. https://www.casio-music.com/euro/keyboards/ It also shows up on the international (Asia?) site for some existing Casio models. https://www.casio-intl.com/asia/en/emi/high_grade/ It doesn't seem to be a term used here in the U. S. however.

Are you sure of the point above which you're not getting sustain? Real pianos don't have sustain above a certain note (next to last F or so I think) and Casio's acoustic pianos simulate this. Some electric pianos also don't have sustain in a similar range, these would be called 60s EP in your Casio. I'm not sure about the tine-based electric pianos.

Plugging in headphones cuts off output from the built-in speakers, which means you can practice playing even late at night without disturbing others.

I had a PX-3 and a Nord Electro Rack (same as Electro 2). It's been a while so I don't remember what I did to configure it, but it worked fine. One thing in your post confuses me, you say "headphones in Privia." What do you have connected to the Electro's audio outs (line out or headphones) to listen to the sounds coming out of it? MIDI doesn't transmit audio so you need something to hear the audio from the Electro, not MIDI.

It was funny when I said it out loud, too. 😅 I've never seen a keyboard that was not a sampler or that couldn't load samples bother to put that in the manual. If you listed everything a keyboard couldn't do, the manual would be enormous and people wouldn't be able to find what it can do. If the manual left out how to do something like what you're saying, that's a legit complaint and good feedback. Casio should be able to update that. But this idea that we should have a warning thread about what this model cannot do is absurd. The PX-5S is not a workstation, should there be a thread about all the workstation features it is "missing"? Should people be warned the CT-X models don't have weighted keys? The CT-X series do what they do, and many of the features and designs are the way Casio has been doing it for years, like it or not. Assuming they would do something because a competitive model does it or does it that way is strange to me. You might want that, you might suggest it to Casio, but don't buy the 'board and be disappointed it doesn't do it that way, and don't be disappointed that it is not made to do so in a "firmware update" (which is something people seem to expect miracles from nowadays). Excuse me, I hear a wave calling…

You are misunderstanding the meaning of line levels and thus Line Outs. Your PSR apparently has a control to set the combination headphones/line out because headphones can use a different level than pro gear. But in either case, the volume knob does affect the volume. In fact, on page 11 of the PSR manual it says you should turn down the volume before turning it on, a common technique to prevent popping external amps and speakers. Then you turn the volume up. The manual for the brand new Kurzweil K2700 says much the same thing, and it does not have internal speakers. It's completely a pro keyboard (meaning: not consumer, if that makes any sense), and the volume knob affects the line outs. If I had a keyboard that had no volume control when connected to external amplification, I'd send it back.

😂 It's a good thing the manual for my car told me what it can't do, because it told me the car wasn't a boat, otherwise I would have driven it into the river. It also told me it wasn't a plane, otherwise I would have tried to drive off that cliff. I wish the manual for my keyboard told me it wasn't a surfboard. It worked very poorly as one.

I think Jokeyman means "button" when he says to clean the "key." They keys seem to work fine, but the Function button doesn't.

Name a keyboard that does this, please.

I'll start. I think it will make sounds.

That usually fixes this. Hmmm.

Even though you've had this occur in different locations, it could still be power related. Do you have batteries in the unit? On one hand, the keyboard should switch to batteries if the power goes out, but I can't say for sure it would smooth out a brownout. OTOH, it might react weirdly by having the batteries in there (I seem to recall some reports of this but I could be wrong, like someone was reporting that their keyboard worked better by not having the batteries in there. It doesn't seem right to me but it's worth being open to). I would suggest that trying the opposite of whatever you currently are doing with the batteries to see if the problem persists. The other thing I would try is to recreate the steps that led to the fault you saw. If you could consistently do it, you could report it and others users could confirm if they can do it as well. Then we could report it to Casio (they would see it here) and they could hopefully fix the bug.

Just because your avatar has an X doesn't mean this thing does (these things do?). Or does it? 🤷‍♂️😇

Absolutely. It is Class Compliant and all you need is a USB data cable that has USB-B (printer style) port on one end and whatever USB your Mac has (USB-A or USB-C) on the other.

If you connect your CDP-S150 via USB, the computer will only receive MIDI data. In order for you to "hear" that, some program on your computer will have to convert that to audio. That can be done in real time, and that could be recorded, depending on the software you have. You could also save the MIDI data and play it back later. Of course, you always have the option to hear the audio coming from the keyboard itself, and you can play back the recorded MIDI data through the keyboard.

Using the full YT link lets people watch it here instead of there.
