Van Halen Jump on keyboard Yamaha MODX Montage

All background music played by me, using my Yamaha AW4416 digital recorder, not perfect, not as tight as I would like, but I am not a professional, just a hobbyist. The drums were finger drummed using my Roland JV80. The bass and guitars are real, not keyboards. The patch I used is my edited version of the Factory patch called "After 1984" The factory patch will work but I tweaked it a little to get it closer as I always have to do with any synth I own. I cannot remember what tweaks I made but probably switched the reverb effect to a slap back delay and possibly detuned the oscillators more than factory and or added a chorus effect.
