chrissk21 Posted March 19, 2017 Share Posted March 19, 2017 Need some help. I play the PX-5S live at church every weekend, and just recently it has started sounding random single notes. They happen at random intervals; usually about 3-4 times in a set. The best description I can give of them is that it sounds like someone is reaching over my shoulder and hitting a single note, out of key and out of time. It's VERY distracting. Here's my set up - Playing a piano stage setting with external audio out from the board itself. Have USB out to Mac laptop to control a synth in Reason. Also have a second keyboard (for Rhodes and organs) with its audio passing though the PX-5S and tied to a fader for volume control. Finally, I have a USB expression pedal going into the mac for volume and synth adjustment. Here's what I've tried for troubleshooting - * Made sure I was on latest firmware * Reset the board to factory (once) * turned off midi-in & USB-in on the px-5s I cannot figure it out. I've used this setup or something very similar for nearly two years. Is there something wrong with the board itself? -CK Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted March 19, 2017 Share Posted March 19, 2017 Best way to find out if it's the board itself is to disconnect everything from it and play it as a standalone instrument. There could be something going on with the internal circuitry. Quote Link to comment Share on other sites More sharing options...
chrissk21 Posted March 19, 2017 Author Share Posted March 19, 2017 Just did what you recommended and played it hard for about 30 minutes. Couldn't replicate the problem. Any other thoughts? Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted March 19, 2017 Share Posted March 19, 2017 Ok. I would begin to reconnect the rig and try to pinpoint which component of the setup causes the issue. Could be MIDI related. Quote Link to comment Share on other sites More sharing options...
Choppin Posted March 20, 2017 Share Posted March 20, 2017 Do what Brad said. Also, what you describe sounds like something I've encountered - usually with older midi equipment. In my case it was clock and sync related. Some midi device isn't syncing correctly and "delaying" notes - that creep up at weird intervals once the hardware handles the event from the bad midi clock sync. Check the midi clock and sync settings on all of your equipment and make sure your master keyboard is set to master and any slaves are set to slave. Also make sure the clocks, counters, or metronomes aren't automatically activated once playing starts. I also had a similar problem with bad midi cables.

Display Name Posted March 22, 2017 Share Posted March 22, 2017 My money is on a MIDI problem as well. Try a new cable. What is the second keyboard you are using? Also is the PX-5S the master or slave keyboard in your setup? Quote Link to comment Share on other sites More sharing options...
chrissk21 Posted April 8, 2017 Author Share Posted April 8, 2017 Wanted to let everyone know that I think I've figured out what is causing the random notes. I'm pretty sure that I have a faulty sensor in one of my F#s. I stripped the system down to just the internal sounds the other night and rehearsed for several hours. I finally was able to repeat the error. Basically, when I press the F# a certain way (like when I'm playing quickly), it will cause the key to resound at full volume on the upstroke. Unfortunately, I think this means a trip to the Casio Services for repair. Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted April 8, 2017 Share Posted April 8, 2017 Well, believe it or not, a simple puff of air in between the suspect keys may fix the issue. I've personally seen air cure a PX-5S with a key that was triggering 127 velocity when it shouldn't. It seems the sensors can sometimes be extra sensitive to debris. 1 Quote Link to comment Share on other sites More sharing options...
chrissk21 Posted April 13, 2017 Author Share Posted April 13, 2017 Brad - tried what you suggested with no luck. I sprayed compressed air in on all sides of the offending F# to no avail. Any suggestions on finding a Casio repair center? Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted April 13, 2017 Share Posted April 13, 2017 For the USA this will work. http://www.casio.com/support/musicservicecenters 1 Quote Link to comment Share on other sites More sharing options...
PraisebandBrian Posted June 20, 2017 Share Posted June 20, 2017 Hello Chrissk21 - I've recently had a similar problem. I also play for my church every weekend. Did you get your PX-5S repaired, and did they tell you what the issue was? Quote Link to comment Share on other sites More sharing options...
