Muff's Modules & More

If so, how?

If not, what in the dotcom line is?

Sorry if this is a dumb question..

This is what I am basing it on: From the Q106 description..

The Oscillator generates the basic waveforms needed to create sounds. Oscillators can also be used to generate control signals for amplifiers, filters, pan/fade and more. Provides 5 waveforms simultaneously, linear FM, exponential FM, hard sync, pulse width modulation, range selection and fine frequency tuning. Can be expanded with the Q141 Oscillator aid module.

plug the output of one oscillator into one of the fm inputs on another one.

Well every voltage controlled oscillator as well as self oscillating filters do FM. Frequency Modulation means just that, you are changing the frequency.

Now the options on exactly how it responds when modulated is where people start looking into details.

Q-106 has a linear frequency input. That's definitely to be desired as it opens up more FM synthesis options.

Lately there is lots of lots of buzz over through zero modulation. You can read long threads and it's still an uncommon feature. Without a long explanation, if you send it larger amplitude modulation voltage it won't go down to no frequency and sit there for part of the wavecycle. Some people people find it essential others not so much involved with musical pitches don't find it essential at all. Anyway being a pretty rare feature, it's not on this is one

Thanks! I have been watching YouTube videos on FM (and doing some reading as well) and I have an idea what you describe. Now to try it!
thumbs up

Woah dude, you're about to be in for a world of fun. Attenuate heavily and use linear if you want the pitch relationship to remain close, and use a VCA in place of an attenuator to spice things up with cv.

A useful book for understanding FM is:

http://amzn.com/B005SJ0GSE

Some of it is crap, but it is a $2.99 ebook that provides some interesting ideas about useful intervals (from a musical sense) as well as how to understand what is happening.

Have a great ride!

Sweet! I have noodled with FM on my MEK/PER and really dig the tonal noise but figured it was a special, super-secret Dave Smith circuit that if disclosed the discloser would be put to death! wink

The main reason for my interest is the MOTM-480 CS filter I scored from a fellow wiggler formite has a big honkin FM input just begging to be used. Being the obliging cat that I am, I shall accomidate.

Damn, this forum rocks! Or rolls, if you are of that persuation.. thumbs up

It can be a confusing topic to a newer user, but any vc filter has an exponential fm input. Some label things differently than others is all. You can use dc or audio signals on any cv input on any module, including your vcas, pwm, sequencer, etc. All an audio signal is doing is cycling at a higher frequency. Try it all!

Don't worry, you aren't even close to being the only one in the room that didnt understand that in the beginning. thumbs up

Hmmm...I thought I understood this but...

The way I understand FM is one signal modulating another. But a filter doesn't generate a signal per se, so how can you do FM by sending a signal into a filter?

hmmm.....
