Looking for recommendations for triple/quad VCO modules
After a few years of directionless impulse buying (and the acquisition of another rack) I’m now looking to bring some sense to my setup - first order of business is setting up a proper four voice synth.
My first thought was to look for an MFB OSC-03 to accompany my Nanozwerg Pro, however it seems as if these are completely erased from existence - no trace on the website and all of the MFB modules seem to have been discontinued. Seem to be quite rare on the second hand market. The Doepfer four voice synth seems very capable but perhaps not the most inspired choice. Trident is very interesting but in a whole different price class, is digital and would take up probably more space than I’d like it to.
Is there anything significant I’ve missed? I’m not ruling out full featured individual modules yet but I want to keep this to as low HP as possible without sacrificing usability. While I’m not opposed to going utilitarian, I’ll be the first to admit that I’m a sucker for fun and or unique features.
One more relevant piece of info - I’m NZ based and so only have access to whatever ships here really.
Thanks for reading!

Just a note: the Rossum Trident is analog, not digital.

Quad VCO, analogue, low hp and “fun or unique features”. I mean, you have to consider Saïch if you haven’t already.

Go old-school: A-143-4. Can't go wrong with Doepfer!

Instruo Troika. It's one of my mainstays. I have a Ts-L and Vinca right next to it, making up a 42 HP Instruo synth voice inside a larger 208 HP rack.
Another one I can recommend is the Doepfer A-111-4.

Re: Looking for recommendations for triple/quad VCO modules
I second this. I just got a Saïch and its flexibility to fun ration is off the hook. For added fun, add a wave folder so you can do from synthy warmness to mangled mayhemRaindeer wrote: ↑Mon Feb 22, 2021 8:36 amQuad VCO, analogue, low hp and “fun or unique features”.

Re: Looking for recommendations for triple/quad VCO modules
Thanks for all the quick replies everyone - as much as I love how the Saïch sounds I’m aiming for individual CV control and as far as I can tell this can’t do that? Again, here to be corrected. Good to see Doepfer gang going strong, anyone vouching for the Doepfer A-111-4? Troika looks great! Pretty expensive but definitely on the list to consider.

Re: Looking for recommendations for triple/quad VCO modules
Someone vouched for this a couple of comments up. Benn Jordan (the Flashbulb) rates it highly in a recent video-walkthrough of his rack--if I remember correctly, he floats the possibility of purchasing a second.

Yup, Ben Jordan did say that in his walkthrough.wrecksmoondee wrote: ↑Mon Feb 22, 2021 9:02 amSomeone vouched for this a couple of comments up.

And I also vouch for the A-111-4. I replaced my Humble Audio Quad Operator with the A-111-4 because I've come to realize that I really prefer analog over digital in VCOs.
But I still think the Troika is my preference if I'm comparing the two.

Re: Looking for recommendations for triple/quad VCO modules
Looking very promising - the FM options seem very good and would be good to have the extra waveform compared with the 143-4. So far it’s between the 111-4 and the Troika I’m thinking but still open to suggestions/debate. As for the guy who prefers the Troika, what do you prefer about it? Will have to sleep on it and check back!wrecksmoondee wrote: ↑Mon Feb 22, 2021 9:02 amSomeone vouched for this a couple of comments up.

- The oscillators sound great
- Each oscillator channel has its own dedicated waveshaper; continuously morphing from one shape to another (see the sliders in the image) *
- Each has a dedicated 1V/Oct in
- Each channel has a dedicated output
- Each channel's dedicated output has its own level pot *
- Each has a dedicated FM input with attenuator
- As well as the individual outs, there's a mix out for all three oscillators

For comparison, I've added two images as attachments; one is my Instruo "synth voice" section in one rack, and the other is the equivalent section built around the Doepfer A-111-4 quad-VCO plus waveshapers plus VCAs section in another rack. The one built around the A-111-4 sounds good too, but it's also different in that I put it together with more waveshaping modules because it doesn't have any built in, and since I had to put more waveshapers in I made sure those have CV over the wave shapes (which the Troika does not have except for a pulsewidth modulation CV input on one channel).
