Ways to limit the LFO range...

Ways to limit the LFO range...

2006-06-26 by danfarmer19732003

Hi guys... I'm looking for what I might call a range limiter for my 
LFOs.

What I want to do is limit the range of the LFO. For example, if I'm 
controlling the cutoff filter with the LFO I do not want the filter to 
close the filter 100%, I just still want some sound(s) to come through. 
I'm finding that as it is right now, there is no EFFECT AMOUNT control 
on the LFO's it just does a straight 0-100% range.

The opposite is true as well, in some case where I do not want 100% of 
the sounds to come through either. Meaning that I do not want the LFO 
opening up the cutoff filter 100%.... again some king of EFFECT AMOUNT 
control would be useful to me.

Can the Deopfer A-136 do this? If not what other module can? I was 
thinking if I routed the LFO through a filter and if that filter had 
bandpass, that that might do what I want.

A-138c polarizing mixer - or the polarizing module (not sure the #).

hello dan,

you can simply attenuate the lfo output,
that would be the simplest solution.

the more elaborated solution would be the use of
one or two a172 max/min modules together with an
a176 voltage source, thats what i'm doing quite often.

best wishes

Hi Ingo... when you say...

"you can simply attenuate the lfo output, that would be the simplest 
solution."

What exactly do you mean? All I see on my LFO's is a rate knob that 
controls the rate of the LFO. Can you give me an example of how to 
attenuate the output?

Hello Dan, Doepfer LFO-modules have no level controll for the output 
but most (if not each) have at least one input with a level control 
(attentuator). The VCFs have usually one input without attentuator 
(e.g. A122: CV1 for an 1/V response) and another one with 
attentuator (e.g. CV2 for those CVs which does not need to comply 
with the 1/V standard). Regards, Ingo (not selfoscilating)

Sorry, for posting this twice. just have realized I missed a word 
which is now added:

Hello Dan, Doepfer LFO-modules have no level controll for the output
but most (if not each) *module* have at least one input with a level 
control (attentuator). The VCFs have usually one input without 
attentuator (e.g. A122: CV1 for an 1/V response) and another one with

Hi again, thanks for your assistance but I'm afraid that I'm still 
not following.

I have the following module and see no input to control the 
attenuation...

Re: Ways to limit the LFO range...

2006-06-26 by ilanode

Sorry, for the insufficient explanation. I'll try again. You go from 
the LFO's sine out into a VCF. Let's assume you take CV1 of the 
A120. This input is calibrated to comply with the 1/V standard. The 
sine output goes (just a guess) from -2,5 to +2,5 thus will swing 
the freq. as if you would manually turn the freq pot over a wide 
range. This is the current annoying situation. However, if you use 
the CV2 or CV3 input you can attentuate the incoming sine wave with 
it's corresponding CV-pot to any range inbtn. 0V and -/2,5V. The 2 
attuators (CV2 and CV3) make of the missing output level control on 
the LFO. Hope that helps, Ingo

RE: [Doepfer_a100] Ways to limit the LFO range...

You should be using the CV input attenuator on the filter for that.  You're
simply looking in the wrong place.

Hi guys... I'm looking for what I might call a range limiter for my 
LFOs.

What I want to do is limit the range of the LFO. For example, if I'm 
controlling the cutoff filter with the LFO I do not want the filter to 
close the filter 100%, I just still want some sound(s) to come through. 
I'm finding that as it is right now, there is no EFFECT AMOUNT control 
on the LFO's it just does a straight 0-100% range.

The opposite is true as well, in some case where I do not want 100% of 
the sounds to come through either. Meaning that I do not want the LFO 
opening up the cutoff filter 100%.... again some king of EFFECT AMOUNT 
control would be useful to me.

Can the Deopfer A-136 do this? If not what other module can? I was 
thinking if I routed the LFO through a filter and if that filter had 
bandpass, that that might do what I want.

Hi,

What module are you connecting it to? That¹s the module that should have the
attenuator, not the LFO.

This is what we're endeavoring to familiarize you with.  The attenuator is
on the CV2 input of the filter.

Hi again, thanks for your assistance but I'm afraid that I'm still 
not following.

I have the following module and see no input to control the 
attenuation...

AW: [Doepfer_a100] Re: Ways to limit the LFO range...

2006-06-27 by Dieter Doepfer

In the A-100 system the attenuators are located at the inputs of the modules
but not at the outputs as this principle is much easier from our point of
view than having the attenuators at the outputs. Most modules have this
input structure for control voltages:

one manual control or offset (e.g. manual filter frequency control)
at least one CV input with attenuator

With the manual control you adjust the offset of the parameter in question
(e.g. VCF filter frequency, VCA loudness, VCO pitch), with the CV attenuator
you adjust the amount of the effect of the external CV, e.g. how much a
triangle output of an LFO modulates the filter frequency.

I hope everything is a bit more clear now.

Best wishes

Re: [Doepfer_a100] Ways to limit the LFO range...

2006-06-27 by Florian Anwander

Hi Dan,

I think you missed until now completely the principles of mixing and 
attenuating control voltages. Everything you want, can be done by the 
cutoff frequency pot and the modulation amount (CV2 amount) at each the 
filter module.

I recommend to read a good book on this.

Florian
