I think I figured it out. I live in Florida. I had set up the piano, played it, didn't notice any problems. Left it while out of town. Came back to warmer weather and I'm now running the overhead ceiling fan. The airflow seems to be causing the tremelo or chorus. No distortion while listening directly over headphones. Problem goes away when I turn off the fan. (I will do a factory reset at some point just for the heck of it. I don't have many presets set and I can't really remember what I even have set.)

Tonight I've noticed for the first time, after having the CGP-700 for 7 or 8 years, that the GrPnoConcert sound seems to have a chorus or tremolo quality to it. But only when coming through the speakers on the top, and also when the cabinet speakers are plugged in. When I plug in headphones and the internal speakers or cabinet speakers are disabled, the headphone sound is fine. I only hear the tremolo distortion from the speakers of the keyboard. I will say that I have the piano in a relatively new room (I've had it there for a month but never noticed it before) and I thought it might be the placement of the piano against the wall. So I tried moving the keyboard to various positions with different angles and distances from the wall thinking it might be some slap coming off the wall, but that doesn't help. Is there anything to the electronics that could be causing the distortion in the signal path going to speaker that wouldn't take the same path to the headphones, that sound fine? Any ideas how I can trouble shoot this further? Maybe take the whole thing into a different room, I guess.

Followup: In the interest of trying another brand for my second digital piano (and I don't own an acoustic piano) I thought I'd try a Yamaha. I bought the P-121 (73 key version of the P-125). Even though it was limited in the amount of sounds and has no display to help with selecting stuff I figured it would be good enough. It is nicely made but it sure feels different. I have smaller hands and a 9th with a 5th or 6th is about as far as I can stretch and even that isn't comfortable. The action on the Yamaha takes more pressure and is just harder to play. I wish I had bought another Casio with the similar feel of my CGP-700 which I like. But Casio does not make a 73 weighted keyboard. I want the 73 key size in my second residence because it fits well into a right angle desk piano setup that allows me to work with a computer and digital piano by swiveling my chair. An 88 doesn't. I'm describing this just to encourage Casio to consider making 73 or even 61 key versions of a weighted digital piano. But also a bigger wish: that Casio would make a slightly narrower key version that would fit smaller hands. Some manufacturer is going to do this as the Asian countries begin to dominate the world market. Why not Casio?

How about a 77 weighted key version of any of these, with large display or not? Does Casio make a weighted key smaller than 88?

Thanks for the responses. I think I'll be going with the PX-S1100.

Sorry to ask naive questions but: When you say "more compact action" is that generally preferred as to be closer to an acoustic piano? EDIT: I am looking at 16 different Casio pianos on an online site page. Some are described as "Scaled Hammer Action" and others are "Smart Scaled Hammer Action". Do they feel different or is it just more expressiveness in the dynamics of the sound. The smart scaled seems to be on some of the less expensive models, like PX-S1100. Also improved sounds: is that better samples or synths, or do you mean the acoustics of the speakers. I am rethinking things and might prefer to not have the extra bulk of a particle board frame like on the CGP-700. I like it and looks decent but I'm thinking a folding X frame keyboard stand might suffice where I intend to use it and if the sound is not too bad coming directly out of the PX-560 or the PX-S1100 it might be more convenient when I need to move it. and if the sound coming out of the internal is really not adequate (the sound from the CGP-700 was fine for me) I could get some cheap external speakers. So I'd like to buy something with even better weighted key action and better sounds, that sounds okay through the speakers in the keyboard and as mentioned I could even get buy without the color display if I am just bouncing around between a dozen nice piano, synth and organ sounds. The PX-560 is almost twice the price of the PX-S1100. Besides the color display that i don't really need what makes it a nicer digital piano? Are some options more friendly for using MIDI via a laptop? Do I want to make sure I get a model with a USB connection, as some models mention USB connections and other don't. (I'm assuming that USB connection is the most convenient way to do MIDI these days. I played around with MIDI back in the eighties when they used dedicated MIDI cables.)

I want to buy a second digital piano for a second location. I am beginner/med level. I bought the CGP-700 in 2016. It seems that it is not on the Casio website at this point in 2021. I haven't looked carefully but it seems that the color display that the CGP-700 isn't on any of the latest products. Is that true? When i purchased the GCP-700 I thought a large color display would be useful for getting around compared to the menus I've occasionally encountered on other pianos when I trying them out. I like the color display and I've gotten used to the one on the CGP-700 now but its not a requirement for a new digital piano because I really only play in the menus a little when practicing. This is all to say that I an open to a new model. I like the weighted key feeling of the CGP-700 and it gets a lot of good reviews but I could go to something else too. Especially if it is mechanically quieter. noisy keys mentioned above are the one problem I have with the CGP-700. So what is a replacement for the CGP-700, or what's a next level up (not too much more expensive)?

I've been trying to learn about the question I asked above: I really like the feeling of my Casio GDP-700. I've gotten used to the weighting of the keys and prefer it to other keyboards that I have sat at for a minute at a time in music store, including some $2000 keyboards. If I were to buy a sample package like Keyscape would my GDP-700 sound the same coming my Casio as it would from another keyboard? I think Keyscape advertises that it uses 32 level samples so i would imagine that you want keyboard that is outputing 32 level midi data. Does the Casio output that? and does a more expensive keyboard do that in ways that can be more expressive? So again, would a high end keyboard sound better than a cheaper keyboard when played through Keyscape or something else? Pretty much the same question I asked last month but I'm asking again in case someone new here sees this that can answer it.

My experience playing around with this a few years ago with a sequencer program was confusing and unsuccessful because I am stubbornly using Linux and there are layers of complexity to setting up the drivers and the audio that are probably not there on a mac or windows machine. I was new to Linux at the time and maybe it's getting easier. But that's my problem. Do all keyboards put out the same MIDI info that allows the software to work with the expressiveness of the sounds? Maybe that's a strange question, but do more expensive keyboards have more dynamic qualities to the MIDI data they put out? Will my CGP sound as good as a $2000 keyboard when it is played through something like the Keyscape software?

I am a relative beginner. I am really enjoying my CGP-700 that I've had for five years. I sometimes got to real brick and mortar music stores and check out other keyboards but I always learn that I like the way the CGP-700 feels. I guess I'm just used to it, but that is to say that I want to keep my CGP. I also have found plenty of CGP sounds that I like, including the standard 01 Grand Piano sound, and a lot of the electronic piano sounds. I have laptop running linux mint and an external monitor next to the keyboard so that I watch youtube lessons and learn stuff. (Also a big fan of musescore and recently paid for a year of access to their library of music, and to support the free musescore notation program.) I have the 1/8" audio headphone output of the old linux laptop plugged into the external input on the back side of the CGP so that I can hear the youtube lessons playing from the CGP's speakers, mixed in with my sounds generated by the CGP. I've watched some youtubes about sound libraries. There is a product out there called Keyscape that appears to have really great acoustic piano sounds. It's not cheap but it seems it would be a significant upgrade to the CGP piano sounds (although as I mention I do find the standard CGP grand piano sound very pleasant). Do any of you guys use external sounds and what does it require to get them working? I assume I take a MIDI output from CGP's USB port and put it into the laptop. And have the laptop loaded with the Keyscape sounds. Not sure what software I need to run. My experience with Linux audio is that it can be tricky. Do any of you guys do this? And does the CGP have the degree of midi output that would allow me to hear the expressiveness of the Keyscape sound libraries?

Okay. So bluetooth is out. I'd like to upgrade my headphones to something comfortable and I was hoping to get noise cancelling (NC). The old bose headphones were good for the technology at the time and did a nice job of reducing the drone of the engine noise in a plane or road noise but are not intended to reduce the noise from my wife watching tv. But they do a little of that. I was hoping that new noise cancelling headphones could do a better job of it and I would buy some if they did, but all the NC headphones I see are bluetooth. So if bluetooth is out for latency reasons then it puts me toward getting some corded headset without noise cancelling but with some blocking of external sound just because of a good fit around my ears, and then they have to be comfortable for an hour at a time.

Okay. I am not going to worry about wearing it out for now. If some day I need to fix it I will attempt that but hopefully that won't happen. On a related subject: As mentioned I am using a corded noise reduction headset. It is early version, probably more than 20 years old. It's not really comfortable compared to the stuff now available. But all the popular current noise reduction headsets are bluetooth. Do any of you guys use a bluetooth headset for this? If so what do you use to transmit the bluetooth from the keyboard to the headset? Do you plug in a bluetooth transmitter into the keyboard's headphone jack (BTW, I learned something just now.... I was using "receptacle" rather than "jack" because I thought jack was the same as the male plug, but looking it up I learned that jack is the female.)

I use a pair of wired headphones about half the time I am playing the keyboard. I have a very old pair of Bose Noise Cancelling headphones. They are from the era before Bluetooth. I am concerned that plugging them in and out approximately once a day is going to wear out either of the two 1/8" receptacles on the keyboard. There are two receptables and I don't consistently use one. I alternate back and forth. So each gets half the use. Should I be concerned they are going to wear out, get loose, and stop making good contact? How many insertion cycles are those receptacles designed for? And if they wear out and I have to replace that part, I am experienced with a soldering iron but not too excited about taking apart the CGP-700 to get access to the receptacles. What do others do about listening via headset?

Yes, I understand the concept of layers. I'm wondering from the video I linked to what sounds on the CGP-700 could be combined to make the sound on the video? I presume he is not playing a CGP-700 as it sounds very rich and thick, so maybe what I have cant ever match that but I could try to get close. I've picked the Digital EP5 and GM Syn-Str2, with a 128/37 ratio.

here is a soulful electric piano with string pad. Does anyone have any ideas how to make something close to this: (of course I'm talking about the tone of the sound of the piano, not playing the notes.... hard for me as a beginner but I am working on it.) also I am new to this..... I think "pad" means a layer, but I'm not sure. l guess it is a string layer.
