Grandmother | 2-Op Analog FM Synthesis

This video explores how to achieve analog 2-operator FM synthesis using Grandmother.
In its simplest form, FM synthesis is a sound design method involving two oscillators, typically using sine waves, where one oscillator is used to modulate the frequency of a second oscillator in order to create a new timbre. Adjusting both the depth of that modulation and the harmonic ratio between the two oscillators can yield a wide array of different sounds, ranging from harmonic and musical, to inharmonic and alien.
While FM synthesis is most often associated with digital synthesizers, the all-analog Grandmother is capable of a wide range of FM tones by incorporating the filter and modulation oscillator as sound sources.

Got my Grandmother literally an hour ago. Can’t wait to finish work to play with this!!

[@murphyjulian7393]

I wanted a week off work when I picked up our GM. Hope you enjoy!

[@haydnr1631]

Trouble is you won’t want to stop playing with the GM to go to work!

[@benoftroy]

such a clear and concise demo of FM. terrific!

[@coaldrops2129]

This is amazing! Would never have thought to do this.

[@ManCalledMif]

The versatility of Grandmother is amazing 🤩

[@ashatur2069]

I've owned a lot of synths in the last 20 years but none of them enchanted me like the grandmother and her daughter.

[@my4trackmachine]

The new black panel is sooo nice.

[@djsandy303]

cant say this is the most musical sound but is informative is revealing the grandmothers possibilities. fm in this context is cool for creating metallic like tones and the moving the modulation rate dial comes up with a lot of different sounds

[@djsandy303]

with this patch moving the envelope amount off centre is pretty interesting as well

[@Midnight4K]

Minimal techno uses FM stabs a lot so if you produce that genre this is really useful

[@armand2493]

Really great, and thanks for the white patch, easy to print !

[@biggrime]

Awesome. Makes me want it even more

[@KevinHenkelMusic]

Ooo nice sounds. This is a great spot to park the filter for pitch tracking too. The bypass to vca part of the patch is nessisary if you mix more sound sources in. Otherwise easier not to

[@Fubuki43]

That’s so awesome! Gonna try it straight away! :)

[@dylanleroysynth]

Very cool. Love the Grandmother!!

[@rabidwombat1545]

I love this series of videos, but I'm having trouble getting that metallic sound. Are any of the other knob settings critical? I can't really see them all very well in the video. Trying this out, I did get something that sounded like the Mario Bros. running sound, which was a win anyway! Thank you for any advice!

[@rabidwombat1545]

Derp I found the patch sheet. Thanks for an interesting video.

[@LikelyLoops]

Awesome video! Thanks so much for sharing.

[@jeremythornton433]

This is just great stuff! Thank you!

[@richardjames111]

Trying this right now!! :D

[@dantarradellas7351]

F’ng Awesome !!!!

[@TheNewNumberTw0]

This is really useful! Thanks!!!!

[@JaredNichols909]

So cool

[@clarkflavor]

Wow, didn't know she could do that!

[@cemolcay]

So in theory, we can achieve a similar result with the Mother 32 since it also has a sequencer, an lfo and a self-resonating filter

[@MoogSynthesizers]

Well not quite, because the Mother 32's LFO doesn't work quite like the Grandmother's. The Mother-32's LFO doesn't offer a sine wave, and its CV input doesn't track at V/Oct. You'll be able to get in the ballpark, but it won't work exactly the same.

[@lukasg.2217]

This video is another reason to get the Grandmother your introduction to modular synthesis

[@IceLocus]

Super cool!

[@mackmccord3743]

Just wow

[@alainbarre7483]

huge sounds

[@bazbeat]

this is not working for me, triple checked all the settings. i got no sound at all. adjusting cutoff, mod rate and mod wheel. nothing. whats wrong u think?

[@bazbeat]

i tryed something similar with the matriarch, i got it to work on that. not grandmother tho. is something wrong with my unit?

[@MoogSynthesizers]

Hmm, it's hard to say. Make sure the filter's resonance knob is turned all the way up, and that you have a dummy cable patched to the input of the filter. The mixer's output is normalized to the filter input, so without the dummy cable you can get phase cancellations from the sinewave getting fed into itself, resulting in silence. If you still get nothing, try and reach out to our technical support staff for some help @ [e-mail]

[@bazbeat]

@@MoogSynthesizers right yes, i did chekc all of that. i will try some more and see what happens. thank u :)

[@soundmapper]

Could it have anything to do with firmware?

[@mastermachetier5594]

Can we get a similar tutorial on the matriarch haha
