Hello, I've just got an answer from Erica Synths and they say it is normal for this VCA to leak a little bit.
Guess I'll have to get myself something different, thanks for everything.
Cheers,
Pricto.
Hi guys, received the Befaco - Out v3 and still leaks as I predicted. I've tried in other places in my apartment and the same. Also when I use the Black Dual EG/LFO, the VCA never closes completely after a CV opening and closing of the VCA, when I pull the volume up of the VCA when it is supposed to be closed by the EG, I get almost a full signal out of the VCA... Don't know if the EG is not working properly either. Will send video to Erica Synths to see if it's working properly or not.
Cheers,
Pricto
I've been using the device always in the same room and area, I'll try other spots of my apartment and outside to discard the possibility of a specific RF creeping somehow in the device and keeping the VCA's slightly open. Still waiting for the Befaco - Out v3 module, will inform of what happens.
Thank you very much for the advice!
Cheers,

Ok, It's what I thought. I suppose it's an impedance issue. The thing is that if it sounds, even pre-amplified, it should be leaking, at least at a very low amplitude, maybe not noticeable when the output signal level is attenuated. I made the comment because I've read that some Buchla VCA's in the seventies leaked and it was part of their charm, I thought that maybe Erica went for something similar. The thing that I would like to know is if all VCA's leak at a very low level, or are there completely silent devices, so as if I connect a very compressed distortion at the end of the VCA it wouldn't pull up the leaking. Anyway, I'm waiting for a Befaco line output module, hope it stops the leaking completely.
Many thanks,
Cheers!
Hi GarfieldModular,
In my Black Quad VCA the bleed it's also dim, and just found out that it becomes louder if the pre-amplification from the mixing board is high (of course), if the pre-amp is low it's practically inaudible. Maybe it is because I'm going straight from the VCA output to the mixer. I also have a Black Dual VCF, and if I patch the oscillator into the VCF and then to the VCA and turn the in level from the VCF all the way down, it shuts the sound completely (as expected). Leaking only appears on the VCA at high pre-amping from the mixer but not from the level control of the filter.
Another curious thing I've noticed is that when I turn up any knob from the Quad VCA, signal starts to appear (at low level pre-amplification on the mixer) at about 11 o'clock, before that point is completely silent. From then on the sound comes up smoothly and gradually, and starts to reach amplitude in what seems a rather exponential fashion. Don't know if this is normal either (maybe I'm just being too picky, I'm a sound technician).
Thanks for the reply, I'll try to contact Erica.
Cheers,
Pricto.
Hello, most probably a beginners error, but here it goes.
I've just got an Erica BQVCA and to my surprise it bleeds, it is never fully closed. Is this a common feature of this module? VCA's that bleed its such a bummer, and FOUR!!?? I have an Erica powered skiff case, so it shouldn't be an issue of cheap power source.
I also got a Black Dual EG/LFO, didn't like it either, it just doesn't go slow enough, very limited in this respect, pretty dissapointing, think I should've spent the money on a MATHS... Anyway, has anyone tried or has a QUAD VCA? Is there a way to fix this bleed? Should I contact Erica Synths?
Many thanks!
Cheers!
This: https://www.modulargrid.net/e/4ms-company-quad-pingable-lfo
Four LFOs in that thing, with periods ranging from 500 Hz down to a ridiculous .0002 Hz (ie: 70+ minutes). And another module in a similar timebase vein that you might find useful is: https://www.modulargrid.net/e/nonlinearcircuits-triple-sloths-v2

Very nice! Thank you!!
Has anyone tried or has one of these for sale?

My goodness, the Double Helix is quite a monster oscillator, heheh. Can't find the range in hz in the manual though...
I'd also like to toss in Pittsburgh Modular's Double Helix dual oscillator. The frequency ranges for both oscillators are absurd, from well below 1 Hz to nearly supersonic, and there's no range selection, it's all there on the same knob sweep. This makes dialing in a specific frequency a little trickier, but you'll definitely be able to cover a wider range than most modules.
-- dinorrific
Haven't checked this one... going to give it a look! Thanks!!!
Hi Pricto,
Here a few frequency ranges of a few modules, at the end it's a matter of checking all the manuals of those modules you might be interested in :-)
Erica Synths - Black LFO - 0.1 Hz - 60 Hz
ACL - QLFO - "a fraction of a" 1 Hz - 20 kHz (I am just phrasing what has been mentioned in the manual)
AJH Synth - Dual LFO & VCA - in slow mode it's 0.01 Hz - 2 Hz
Doepfer - A-145 - Standard LFO but I love this thing and have a look at this copy/paste from Doepfer's website:
H: about 10Hz - 4.5kHz
M: about 0.1Hz (10 seconds period) - 50Hz
L: about 0.005 Hz (3.5 minutes period) - 5HzHow slow do you want to go? :-)
Instruo - Ochd - 25 minute cycle till 160 Hz (even slower than the above Doepfer)
IO Instruments - Themisto VCO but can go from 0.5 Hz - 6 kHz or from 10 Hz - 130 kHz
Joranalogue - Generate 3 - VCLFO mode 0.0028 Hz - 180 Hz
Make Noise - Maths - from 25 minutes up till 1 kHzWell that's what I could come up with in checking about a half hour the manuals from several manufacturers. Perhaps there are already one or two modules that might interest you otherwise just keep checking all the manufacturers and their manuals :-)
Good luck in finding the right LFO and kind regards, Garfield Modular.

Wow! Thank You!! Yes, that's what I've being doing, checking the specifications of all the modules but none would have this really wide register that the Neutron has... 0.01 hz to 10 khz and with one knob sweep. I think the Maths has the widest range of all of the modules I've been checking, but still doesn't go as high. Curious, it seems Behringer has gone pretty extreme on this feature.
Man, I LOVE the Neutron's 3340 VCOs! haha The blending and cv mod of the waves... Magnificent! My favorite part of the synth actually. Was sad to see them go once I sold it but felt the Dreadbox Hysteria was a better replacement. The morphing LFO was very cool too.
By the way, the Neutron's LFO is digital so you might want to keep that in mind when shopping around.
-- catwavez
Have to agree, the wave blending and cv mod of these 3340 is really nice, haven't seen anything like it either... What I don't like is the stability of the knobs, I'm avoiding keyboards and other non-knob controllers, just fell in love with knobs I guess. My experience is that in my Neutron one of the VCO's jumps and wiggles at some area of the range when I tweak it. The same with the freq knob of the filter. Maybe is that I have to clean it or something, but is a weird wiggle, and Behringer its so cheap that who knows... but the other one is fine. All in all, I'll never sell my Neutron, I would even buy another one if I could.
Didn't know the LFO of the Neutron was digital... I'll keep this in mind! Many Thanks!!!
I don't know any.
But many LFOs accept a wide range of control voltages, so you could patch a +/-10v CV source in the form of a big knob or a fader into one and get the result you're looking for.
There are many such CV sources, and they're usually cheap. My favorite one is the Antumbra Fade. (It also doubles as an attenuverter.)
-- fredeke
Oh... This could be a really nice way to solve this single knob problem, Antumbra Fades are quite cool... THANKS!
Intellijel Dixie II+ is a pretty solid VCO/LFO and only 40mm.
-- troux
Yes I saw this one, this is the closest option, but it has the switch that cuts the range in half, making it imposible to make a full frequency sweep across the whole register... Thanks for the recommendation anyway!
I think you might be best off with a VCO that has LFO mode - or just goes deep down. Doepfers A143-9 might be a good contender as well, and it’s really cheap! But it only does sine waves and its derrivates.
If that’s what you need - recommended! It’s very modulatable, I use mine as FM modulator with v/oct into cv1 and a nice slider into the cv2 for playability :)
-- LYFoulidis
That's a cool modulator, 4 sines at different phase is very nice... But I have a problem, I've got a skiff case at the moment. Hope I'll get another one in the near future for Doepfer only, aaaargh! At the moment I would be blessed if I had at least one 0.01 to 10 hz LFO with just one knob for the whole frequency range. Thanks for the recommendation!
Hello everyone,
I'm just starting my modular delirium, I've always used conventional synths, but after purchasing a pair of Bastl Kastle and a Neutron from Behringer I went down into the rabbit (or pork) hole and decided I wanted something similar but with more and better oscillators and filters, and more LFO's (yeh, and VCA's, FX, ADSR's, etc... WTF).
While getting my setup I've come across the fact that I can't find an LFO module with a range as big as the Neutron's, which is about 0.01 hz to 10 khz, and in which you can do the full sweep with one knob, no extra "range" knobs (Neutron's LFO is very nice by the way, don't like the oscillators and filter that much though).
I need an LFO module with these characteristics -wide range and complete sweep with one knob- but can't find any, does anyone know of one? Or should I just forget about it and use wide range VCO's as LFO's? (Neutron's VCO's go from 0.7 hz to 55 khz... awesome, but not slow enough).
BTW, I am a knob enthusiast, so I really like good knobs and I like them large for wide modulation.
Thanks in advance,
Cheers!
Pricto.
