I have no problem making new musically useful sounds on my old DX7II
from scratch, maybe other have.

Bummer the JX series don't have FM, what you are referring to is Sync.

I see... You think FM and Sync are the same its not. and it doesn't
sound the same.
FM = The frequency (the pitch) of and oscillator is modulated
typically by the output of an other oscillator.
SYNC = For example if oscillator1 is the master and oscillator2 is
the slave oscillator2 wave forms is re triggered each time Oscillator1
have played a wave cycle

I agree at least they should have made it so the output of an oscillator
modulate the frequency of an oscillator, at first it seems it does but I
found out it is only using a triangle wave for FM.
