you asked about contact cleaner on the joystick. the pivot point where you sprayed is not an electrical contact but there are two potentiometers on the x & y axis. although I’ve never cleaned mine
Had a JX-3p, D20 and M1 some twenty or so years ago. Liked the JX best. Currently having a Subsequent 37, Jupiter 50 and KingKorg as my mains with TR-8s. The synths imho compliment eachother in a great way
@@BellaBell_From my research i know they are on different "sound creation engines" but some sounds are sample based and they are probably the same. That's why most Korg keyboards sounds very similar and share many sounds.
