Have you tried using battery power? That should answer whether it's the power adapter or the instrument itself.

Have you turned it off since then?

Have you actually played a real acoustic piano? I have. I own one. I don't go between it and my CT-S1 (nor any of my other Casio keyboards) and notice any difference in the size of the keys. IMNSHO, you are wasting your time with this. Either the CT-S1 works for you or it does not. I have not heard a single other person complain about the key size of the CT-S series, and in fact, most people are blown away about the combination of portability and sound quality. I have a friend who busked across the U.S. with her CT-S1 and loves it. She also has an acoustic grand piano at home.

I don’t know where you’re getting this information from, but the keys on the CT-S1 and the rest of the CT-S models are full size. See the attached images from Casio’s CT-S1 product page.

That's an interesting problem/solution, and points out why we have these forums. I never considered the fact that one of the pedals might be kicking in (pun intended) and thus making the instrument sound slightly off. Thanks for sharing what happened, now we have another potential solution to suggest if something like this comes up again. Granted, we can't ask people with certain models to unplug the pedal unit, but there are many others where that's possible. Or, we can suggest they try and see what happens when they press the various pedals. For instance, if one of your pedals was acting in reverse, it might have sounded fine with the pedal pressed. Then we can tell them that needs to be fixed.

Sweetwater covers you for two years after purchase. You should give them a call. They’ll see if they can get you going with support, and if not, take care of it for you.

First you have to tell us what tone you want to hear.

It’s not like the action on a real acoustic piano is absolutely silent, but you just can’t really try it without hitting the strings or something in their place. Play your PX-S7000 and enjoy it.

I saw the video of it that Sweetwater posted and they said it was a prototype, so it's likely to change. This guy had a lot of critiques of it if that's the case. I doubt this is the final shipping version.

Because you're new. We had to set limits because of spammers. Some mornings we would wake up to dozens of junk posts by one account. Fortunately the forum software makes it easy to mark an account as a spammer and all the posts would go away, but in the meantime the place would be a mess. It would be nice if we didn't have to make real users jump through hoops to post here, but the spammers ruined it for everybody.

There are additional sounds (really they are reprogramming of the sounds that come in the PX-5S as you can't add sounds to it) available in the PX-5S area of this site that you might prefer. The PX-5S is highly programmable and many have found that tweaking some of the sounds has made them happier.

I hardly hear it on the unmodified part, and even then I have to listen for it. I think part of what's happening now is that phenomenon of, "once you hear it, you can't unhear it." In my personal experience, I can unhear or forget about things with the right kind of effort. You can't not hear it by saying to yourself, "don't think about that sound" just as much as if you said, "don't think about the Empire State Building" if you didn't want to think about it! Maybe that's what you could do. Every time you start to think about that sound, tell yourself, "don't think about the Empire State Building." That kind of thing works for me!

They bought Moog fairly recently and just last week apparently laid off a number of employees at Moog's Asheville NC headquarters. It's not looking too good.

Headphone ports would be audio only. I'm not sure there's an audio in on a Mac mini, it might depend on the model. But it wouldn't "recognize" it as much as see signal in something like a DAW like GarageBand or Logic or audio app like Amadeus Pro. USB out from the CT-S300 should connect to USB on the mini and give you MIDI data (use the CT-S as a controller with the sounds coming from the mini). GarageBand and Logic will show you if they're seeing MIDI data, and MINI Monitor is a useful free app to see the data being received as well.

Regular headphones usually have a TRS plug, which stands for Tip Ring Sleeve. If they also have a mic, then they are often TRRS, with one of the rings being for the mic. Unfortunately, sometimes headphone jacks that are expecting TRS won't work well with TRRS plugs, which have become more common with the proliferation of mobile phones. You can look up more information about these online using the above as search terms.
