Watch some VCV Rack videos on YouTube. Reproduce patches to see how things work and learn how things link together. Read the online manuals. Learning to fish is more rewarding than continually asking people for fish.
you can reproduce the Dexed using mostly of the oscillators of the VCV Rack, or using the Valley Dexter
if you are not familiar with the FM (usable ) synthesis, the main goal is how the Carrier is modulated in the time by the modulator , you should modulate the amplitude of the modulator to achieve different result on the carrier. (the frequency of the modulator mater too, as well if it is already modulated by other modulator or by itself )
everything else is experimenting.
open the dexed (serum and massive ) , then try , and tel us how is going
oh, no problem! Dexter is quite cool. Oh, and also, I should point out that the Bogaudio modules are all very high quality. At least all the ones I’ve looked at carefully are, and I assume most of the rest are, too.
Dexter is great but Terrorform is greater. (And FMOP and Kitchen Sink are great too). Some of my first youtube vids were with Dexter back before I knew anything at all about synthesis. Or production. Or anything really.
Terrorform was originally a standalone version of the operators in Dexter and then got a bit…compilcated. I think it was always meant to be used as FM but does a load of other stuff. Looking at the manual (Terrorform) it has various FM modes.
Terrorform does both “True” FM where the frequency actually is being modulated, and DX style which is phase modulation, which has the side effect of modulating frequency but retains the original phase of the carrier signal.
Oh, cool, thanks! yeah, most of my “FM” VCOs actually use phase modulation, for the usual reasons that I’m sure you are familiar with: PM doesn’t have that problem where DC builds up and make you go “out of tune” and PM tends to sound like it has the same “FM” depth across as the freq varies.
