Hello all,

My newly acquired jx3p seems to be in great working order except for one very big issue. The lowest 8 keys of the synth (instead of triggering notes) trigger different memory bank locations, tape memory activation and sequencer operation?! I'm really confused by this as I used to own a JX and also can not find any info online about this weird mode. Besides this I'm still able to use all other functions properly. Hmmm

Best,
Eric

Yea it was a bit dirty on the inside and someone suggested it may be a short in an IC caused by dust. It has stopped it's strange behavior recently and now it only happens every 10th or so time I turn it on. Im gonna have to clean it out again and see what happens. One of the keys doesnt trigger sound but that can be fixed with some rubbing alcohol correct?

A good cleaning of the circuit with alcohol or acetone should help.

For the keys themselves, check whether there are these strips of metal contacts beneath like the Roland JX-8P and the Korg DW-8000. If so, you can try spraying the contacts with a contact cleaner, once between the middle contact and the lower one, and then after pressing each key, between the upper contact and the middle one.
