Ben0Bray Posted October 31, 2017 Share Posted October 31, 2017 I have a Casio CDP-100 I haven't used it in a long time (I find the keys too heavy) I've attached a small sound clip of the issue - I'm hoping it's just loose solder The first note I hit is with the piano on under half volume. the last two are on full volume IMG_0574 (1).mp3 Quote Link to comment Share on other sites More sharing options...
CYBERYOGI =CO=Windler Posted November 30, 2017 Share Posted November 30, 2017 I am no expert in CDP-100, but the symptome looks like a power supply issue (or dead batteries). The instrument will keep resetting (likely also changes preset sound and rhythm to default if it has that) by voltage drop during loud notes played through its internal amplifier because this draws higher current. Do you have connected it to a too weak (less mA than rated on the instrument, e.g. 300mA instead of 1A) non-original AC-adapter? Also a broken AC-adapter (e.g. bad capacitors) may cause this.
