You can do the "feeding/modulating it with its own or another VCO´s output"
thing. Like X-MOD on the Mono/Poly.∗∗
As Paul H. wrote, however, it's a long way from there to doing it the
"Yamaha DX7 way".
It's been widely stated that VCOs are not accurate enough for true, DX-style
FM work, and that is why Yamaha went with DCOs. But maybe it was also a
matter of cost? (Well, we ∗know∗ that cost is always a factor.) Question is,
how accurate do the oscillators really have to be?

∗∗ I have a Mo/Po, too. Turned it on the other day for the first time in
months, and it was not tracking in tune. It's been perfect for over 20
years, so I was a little bummed. Hopefully it's just a matter of
calibration, but I'm fearing that caps and/or some CMOS chips are due for
replacement. Not rocket science but it will be hours of work. :-/

Subject: [motm] VCO FM question
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
