MOTM

Hi

I´m still a bit new to MOTM and dont have any MOTM VCO´s yet. (using 
my old Korg Mono/Poly as main VCO´s) Can you do FM in the "Yamaha DX7 
way", with it? (feeding/modulating it with its own or another VCO´s 
output) Or is this only possible in a virtual digital domaine?

greetings

Gregory
