MoogerFooger MF 103 - Chorus / Flanger?

Post by dillivered » Tue Sep 20, 2005 10:34 pm

Dear Userbase:

Can you help me...I just purchased a 103; should I be able to get chorus and flanger type sounds? I haven't played with it a whole lot but as a modulation effect, these sounds should be resident, correct?

Thanks!

Chorus and Flange are both time based effects. The work by modulating very short delays. Phasers are filter based effects. It modulates certain frequencies and has nothing to do with delay.

I think. :)

Hello,

On point. Because the phaser is basically an allpass filter, the dips (notches) introduced into the frequency spectrum have no harmonic relationship as with flanging.

I was flanging pretty well with the MF-104 and SD both set to pretty short delay times. but I'd still like an outright moog flanger...

Flanging settings?

Hello Dealer, I pre ordered my 104z and currently have a Boss DM3 analog delay. Is it possible to create the Flanging effect with this two pedals? and if so, would you be able to post some settings? Are you supposed to use an LFO to modulate the Time in one of delay pedals to create the Flanging?

Best regards, Daniel Trejo

Moreover, phasers use inverting and non-inverting amplifiers in a single op-amp. The inverting amplifier basically inverts the phase which has no effect until you mix it with the original waveform. Then you get cancellation in specific bands - and voila the dips are thus born.

For every dip you need two all pass filters. (This is why you don't see 3, 5 or 7 stages). The MF-103 uses 12 allpass filters and so we have 6 dips. Or three.
