MusicalSeries Posted February 23, 2021 Share Posted February 23, 2021 Good afternoon everybody, I'm new in this forum and I need some advice from more expert people about my issue. On August 2020 I bought a Casio CDP-S100 digital piano. All fine, but on December I had to call the reseller for replacing it. The piano was stuck on sustain without holding the pedal. I tried every solution I found (Holding pedal while turning on, ecc., ecc., ecc.) but the piano seemed not to follow rational patterns... (It worked properly only randomly). On January arrived the replacement. All perfectly fine, but now the nightmare has come back. What's wrong with the keyboard?

Brad Saucier Posted February 23, 2021 Share Posted February 23, 2021 To be clear, is this happening without a pedal connected to the keyboard? Quote Link to comment Share on other sites More sharing options...
Random_Vibration Posted February 24, 2021 Share Posted February 24, 2021 Could you tell is what brand and model pedal you are using? Sounds like an incompatible pedal. Quote Link to comment Share on other sites More sharing options...
MusicalSeries Posted February 25, 2021 Author Share Posted February 25, 2021 When this "nightmare" happens no matter how the pedal is: plugged or unplagged it will be stuck on sustain. I'm using this pedal (https://www.amazon.it/dp/B085DJ2W47/ref=cm_sw_em_r_mt_dp_M7G0R35MWB0QBRFQ988G?_encoding=UTF8&psc=1), but when I change it with the casio original one nothing changes.

MusicalSeries Posted February 25, 2021 Author Share Posted February 25, 2021 I found something but has not solved the issue. When I press at the same time "Function" and "Grand Piano" it starts playing automatically a preinstalled piece. From that moment until I turn off no sustain is present (opposite effect). When I switch it off and turn it on again the nightmare comes back. Quote Link to comment Share on other sites More sharing options...
IanB Posted February 25, 2021 Share Posted February 25, 2021 When you sent it away before, did you get back the same keyboard or a different replacement? If it was a replacement, was it brand new in box or refurbished? 1 Quote Link to comment Share on other sites More sharing options...
MusicalSeries Posted February 25, 2021 Author Share Posted February 25, 2021 I've got a replacement of the cdps100 and it was new. Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted February 25, 2021 Share Posted February 25, 2021 You said that sustain occurs with no pedal attached and that it happens directly after powering on. Is this correct? Did this happen immediately after opening the new box? Quote Link to comment Share on other sites More sharing options...
MusicalSeries Posted February 25, 2021 Author Share Posted February 25, 2021 Issue solved! Someone told me to do this: Unplug the piano (power) then the pedal. Plug the piano (power), turn it on, and once it's turned on plug the pedal. Follow this pattern, because it solved my issue! Order is the key Quote Link to comment Share on other sites More sharing options...

Plug the piano (power), turn it on, and once it's turned on plug the pedal. Follow this pattern, because it solved my issue! Order is the key If you have to do all that, I suspect once again the pedal is the problem. You can switch pedals after it gets confused and it still will be confused until it is reset. You are effectively resetting when you unplug the keyboard. Reset it and only use the Casio pedal and see if the problem return. I am very suspicious of off brand pedals claiming universal capability. I have a Yamaha keyboard and never used a pedal that works well with it with a Casio. Sometimes there's more than polarity to worry about. I use Casio and non-Casio pedals but from well known brands. That ambiguous pedal you use is a complete unknown to me. If ever I were to run into a problem like this: 1) Reset the keyboard 2) Get a Casio or known reliable with Casio pedal. 3) Look for repetition of the fault. When using a compatible pedal, you don't have to reset the keyboard to get it to work. It just does. Reset and stick to the Casio pedal.

Hollow Posted June 8, 2021 Share Posted June 8, 2021 Hello, Random_Vibration! A question here: which off brand pedals are compatible with casio? Could you recommend me a brand of weighted pedals? Thx Quote Link to comment Share on other sites More sharing options...
Casiofun Posted June 8, 2021 Share Posted June 8, 2021 Try an M Audio pedal. I've used that with every Casio I've owned WK-7000, CT-X 5000, PX-330, PX-575, Roland FA06. Quote Link to comment Share on other sites More sharing options...

But can't solve it like that , also although playing the demo does reverse the sustain on-off, the pedal doesn't work. I'm using a Casio SP-3 pedal, working well with my XWP1. I guess it's a repair in my case. Edited July 14, 2021 by mertyuy Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted July 14, 2021 Share Posted July 14, 2021 Yes, that does sound like a repair issue. The Casio SP-3 pedal should work fine with any Casio instrument. Quote Link to comment Share on other sites More sharing options...
Ekhlas Posted August 26, 2021 Share Posted August 26, 2021 I've got the same issue. I've tried to use the pedal which came with the piano and another pedal. And a reset doesn't help. What should I do? Quote Link to comment Share on other sites More sharing options...
Lee24 Posted September 8, 2021 Share Posted September 8, 2021 This helped me out with my problem. https://www.justanswer.com/electronic-musical-instruments/84nzv-technics-p30-digital-piano-sounds-sustain-pedal.html I used the sustain pedal that came with the Casio CDP-100, and instead of using rubbing alcohol to clean the pin, I used a dry tissue paper. After about 5 times or so, putting it in, wiping the pin, pulling it out and putting back in, the sustain pedal work. I then cleaned my other sustain pedals pin with the tissue paper, put it in and put it in, and twisted it a bit as I put it in, and it also worked from then on. I hope that helps.

Reges Mesquita Posted October 11, 2023 Share Posted October 11, 2023 Bom dia pessoal, Também estou com o mesmo problema. Nem resetando deu certo... Quote Link to comment Share on other sites More sharing options...
Solution Brad Saucier Posted October 11, 2023 Solution Share Posted October 11, 2023 Steps to solve. Note: If the keyboard is brand new and this happens out of the box, contact your dealer for assistance. 1. Confirm pedal is Casio compatible and not faulty. Test pedal with another keyboard or use a resistance (ohm) meter to test the pedal. 2. Confirm pedal jack on keyboard is clean, no foreign objects inside of jack, dust or debris. Clean jack if necessary. Insert plug several times to help clean, or use a cleaning tool and compressed air. Quote Link to comment Share on other sites More sharing options...
