MOTM

In order to do DX type FM you need the ability to linearly frequency
modulate a VCO through zero.  While the MOTM-300 is capable of linear
FM, it does not have through zero capability.

I'm unsure whether or not you need oscillators which reset to zero on
the leading edge of a gate.  This may not be necessary, but I assume the
DX series does reset to zero.

Even if the MOTM oscillator was capable of meeting the above criteria,
you would need a very large system to replicate the DX7.  Six VCOs, Six
VCAs, Six Envelope Generators at the minimum.

Personally, I would welcome a new MOTM VCO with these capabilities, but
I haven't heard anyone else except Dave Bradley express the same
sentiments.

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
