10thumbz Posted December 21, 2017 Share Posted December 21, 2017 When playing in mid range,sometimes an extra note (usually D# or F#) sounds out on my PX-5S. This isn't my mistake,as the arrant note sounds after my hand(s) have moved on. Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted December 21, 2017 Share Posted December 21, 2017 Can you upload a short wav file demo. Quote Link to comment Share on other sites More sharing options...
tielemat Posted July 26, 2019 Share Posted July 26, 2019 I have exactly the same problem since a couple of days .. since it is completely random, it's hard to make a demo of it .. any suggestion, please ? Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted July 26, 2019 Share Posted July 26, 2019 It could be a dirty sensor. Try blowing some air between the problem keys. Quote Link to comment Share on other sites More sharing options...
Redwave Posted July 29, 2019 Share Posted July 29, 2019 This seems to be the most common hardware failure mode of the Casio PX-5S, and has been happening for me on the G#3 key for a couple of years. Blowing compressed air between the keys hasn't worked. Since the extra "ghost" note always has velocity 127 and I don't hit the keys that hard, a completely effective workaround for me has been to set maximum velocity to 126 in any stage setting zone where I might need to use G#3.

Tom Williams Posted July 30, 2019 Share Posted July 30, 2019 Blowing air might not fix it, but I bet a cleaning of the keyboard sensor will. I've experienced this before with a MIDI controller. Although I am not an electronic engineer by a long shot, I believe that velocity is calculated by the time between activating one sensor and the next. If the first sensor is not activated, the software "guesses" that the time was instantaneous, and calculates that velocity was very fast indeed. I suspect that the engineering rationale was that it's better for a note to sound too loudly, than to not sound at all. This has the one functional value of making things still work for non-velocity sensitive voices, either in patches or under MIDI control. Or for us rock-n-foll folks who slam on the keys all the time anyway. 🙂 Quote Link to comment Share on other sites More sharing options...
