problem with cp 251 (is there anyway of getting around this)

The Moog Forum Moogerfooger Forum

okay you know how if you want to control one of the moogerfoogers performance parameters like the lfo depth (amount it affects what it’s hardwired to) you can use the amount knob a pedal or another cv input
but if you wanted to use the lfo to modulate another moogerfooger then the only way you can change the amount of the effect is with one of the attenuator knobs on the cp 251 (or similar)

the problem with the 251 is that it doesn’t allow you to use an external cv to control the attenuation it only has one knob per attenuator and NOTHING ELSE. you could do so much more if you had that input (but they would be very subtle changes to the effects and sounds but it would extend what little bouderies there are even further).

i suppose it means that each moogerfooger only shares it’s modules, it doesn’t completely give them away. only the function the lfo (or env flowr or whatever) is originally assigned to has complete control.

of course none of this affects me because i don’t have any moog gear (tears roll down my face :frowning: ) at all.
but I have just ordered the standard etherwave (yesterday) so i’m looking forward to that. I intend to start buying the moogerfoogers this year and eventually the rack mount voyager.
but that will come later.

“the problem with the 251 is that it doesn’t allow you to use an external cv to control the attenuation it only has one knob per attenuator and NOTHING ELSE.”

That’s all the attenuator is supposed to do!


“you could do so much more if you had that input…”

A VCA is essentially an attenuator with a CV input. It would be cool is there was a MoogerFooger with a VCA and maybe a VCO.

“A VCA is essentially an attenuator with a CV input”

really?

I thought you would be able to use the attenuator as a VCA in the orientation i put forward but then, as i do not really understand the electronics of it, I was not sure (maybe there was some crazy audio amp thing that makes it not possible/more complicated) but if you say it is “essentially” the same then that gives even more reason to have included the CV input alongside the knob,
it would instantly make the cp 251 a lot more powerful without taking up any extra room apart from 2 jacks (which isn’t all that much really) to have two attenuator/VCAs rather than ust two attenuators.


"That’s all the attenuator is supposed to do! "

by the by, i was not intending to put the cp 251 down at all, merely to suggest an improvement, and i wasn’t saying that the attenuators on the cp 251 are lacking at all, but when you look at the amount knobs on the moogerfoogers, they are essentially attenuators (hardwired to a particular module) that have CV inputs so you have more means of controlling them than just one knob as per normal, but if you want to use that module with a different effect unit (different moogerfooger) then you have to use the cp251 to attenuate the signal and that is where the amazing control possibilites within each effect are lost without.

i haven’t used the cp251 but have studied the manual and taken long looks at front on pictures of it till i understood all it’s functions completely (without the context of actually using it but hey) and it is a very usable tool i can see, but a VCA (and a VCO if you don’t count the carrier osc) is the only thing missing from the foogers/cp 251 set up, as many people have continually pointed out.

i’d like to see a cp 261 or whatever with:

1-couple of VCAs for modulation control of other CV modules. 3 jacks; signal input, control input, output. maybe a knob: attenuate control input.

2-couple of dedicated inverters, not tied to a mixer thingie. no knobs, no attenuators, just inverters. 2 jacks; input, inverted output. maybe a knob: bias adjust.

3-a mixer like 251 with inverter/bias voltage thingie. four knobs, 6 jacks. see cp251.

4-a VC LFO that gives us a real honest to god sawtooth wave without monkeying with VC inputs or patching to a ‘lag processor’. perhaps a ‘hi freq’ mode for that LFO so that it could also be used as a traditional VCO for us moogerfooger whackos out here. ‘sync’ input so it can be restarted from anywhere in its duty cycle. yes, i’m asking for a real VCO. heh heh. a bazillion knobs, a couple dozen jacks. :wink:

5-maybe a mult if there’s space remaining; four jacks. 1 input, 3 output.

no need for more s/h units, thanks.
no need for additional lag processors…weeelll, maybe if there’s room :slight_smile:
…two knobs, two jacks.

lessee, would all that stuff fit? hmm.
maybe cut it down to a half-bazillion knobs on that LFO/VCO?

…heck, and how about a signature set of ‘port-a-pots’ and ‘multimults’ or whatever those things were called. uncle bob can write things on them like

‘why the hell don’t you lazy kids solder up these damned things yourselves? get to work!
love; Bob Moog’

…or somesuch. ;D

ps: getting back into my little neglected 101 moogerfooger. that’s one nice filter there, i say. especially when it’s played like an instrument. very responsive and musical. i’m liking the 2pole mode in conjunction with subtle tweaks on the ‘mix’ knob…very good on hi freq drums like cymbals and hihats.

Hi,

theres an expression pedal out there – god i wish i could remember what its called … it has a tube that connects to a little cup that molds to knobs, and when you press the pedal, it mechanically turns the knob its attached to!

I wish i bookmarked that site! Anyway, know that it does exist.

its called the ‘3rd hand’ much like the Electro-Harmonix Hotfoot. Heres a link:
