another post I read someone said they had something like 7 jd 990's, atm that's the next synth is wanna get, hey who ever that was, I think you can get buy just fine with 6 and sell me one

I am not really understanding why someone would have multiple synths, well I can if it is vintage stuff and you want to have spare parts for when s**t breaks. but can someone please shed some light on the multiple synths for me???
