MF-102 Waveforms

btw, the lfo is a triangle and not a sine as stated in the manual and printed on the unit

There is no sine wave in the Ring Modulator.

As stated, MF-102 LFO outputs "perfectly zero-centered" 2 Volt Peak to Peak TRIANGLE wave (swing between -1V and +1V) and 2.4 Volt PP SQUARE wave (swing between -1.2V and +1.2V)

The carrier is a TRIANGLE wave, 2.5 Volt Peak to Peak.
On my MF-102, there is a little positive offset (is this normal ??).
Centre is not zero but rather +0.1V or +0.2V...

Triangle rules ! :wink:

Here's a Triangle waveform (audio IN) modulated with TRIANGLE then SINE wave (carrier IN)

No big difference in this case.


As carriers, SAW and SQUARE waves has differenteffect...

Yes, I am well aware of this now. Thank you for dredging up this year old thread. :roll:

There was no scoop in fact : I've just realized it was explained page4 in "Lord of the Ring(Modulation)"


I guess that everybody talks about sine waves (as carrier and modulator signals) because of the mathematical theory of ring modulation...the sum, the difference, and all that boring stuff...

The scoop is : part of MOOG magical chemistry sound is using TRI as Carrier !

Hope it can help :wink:
