I keep seeing the Soundforce Dual Filter (https://www.modulargrid.net/e/soundforce-dual-filter) in various racks and videos and would love to hear from people using it. I keep hesitating about buying one, after all price wise it looks amazing. So, any thoughts about this dual filter would be really useful - in helping make a decision one way or the other.

Thanks in advance.


Hi Joesh,

I was at the Superbooth 2021 at the Soundforce booth and I heard a demo of the DCO (2021 version, four of them actually) in combination with the VCF/VCA 6 module (thus not the dual filter you are referring to), and that seriously sounded fantastic. I think on the Internet/YouTube you can find one or two videos about it and/or on Soundforce's website.

Sorry that I don't have any demo I can let you listen at. I consider two DCOs and that VCF/VCA 6 module, that's serious stuff indeed :-) If I ever get to that I might upload a demo of that here in the You section but I think that would take quite some time since I have planned first quite a few other things to buy before getting at this Soundforce stuff.

Kind regards, Garfield.

Hi Garfield, thanks for the info.

I have indeed seen some of the videos featuring the DCO, the VCF/VCA and the have a very interesting Dual LFO too now (https://sound-force.nl/?page_id=4428), which I'm hesitating on buying to replace my Doepfer Quad LFO module - I think it's also in kit form.

As for the Dual Filter, DivKid does a long review, which is great. However, what I was interested to discover is some hands on testimonies from those who spend their hard earned cash on the module, to find out what other people think.

Thanks anyway.


I have just ordered the dual filter and dual adsr. The feature set and sound, as far as I can judge from the few available videos online, appear excellent for the price. Guess customs have their hands full at the moment, so I'm expecting to wait 3-4 weeks...


Hi Thermal,

Wow, that's great. I wish you a lot of fun with those modules and please keep us informed about your experiences with these two modules.

Have fun (after the waiting time for delivery ;-) ) and kind regards, Garfield.

Ok so I have had the modules for about a week and first impressions are good. Sturdy build quality and nice feature sets. Have my Dual Filter set to LP+HP. Cool that I can switch to dual LP or HP for stereo filtering if desired. Bit of a shame there aren't switches for this on the face of the module as it's a pain to take the module out mid session to swap the jumpers on the back. On the other hand it's great to at least have the option. Another slight gripe is the mini knobs for attenuating the various inputs. The panel is pretty crowded, especially with a few cables plugged in, which makes tweaking the knobs kind of a surgical procedure. Compared to not having attenuators/attenuverters at all, though? A real bonus.

Both the LP and HP sound great. I suppose they are fairly clean for an MS-20 style filter, but there's still a lot of character to the sound.

The Dual ADSR is deep and I haven't gone to town with it yet. But it's very versatile and modulating the individual stages separately is awesome. The sliders are nice as well.

in case you have 2HP left it shouldn't be that hard to turn a blank panel into a non-destructive breakout module with a few small switches.
with long jumper cables it also would be possible to place this breakout module in the row above or below...
two years ago i made something similar https://www.modulargrid.net/e/other-unknown-a-128-bypass-breakout


hey that's a cool idea. Don't reckon I have the DIY skills required though. Can you just use some special cables in place of the small shunts that currently need to be physically moved from the LPF pins to the HPF ones? Is this what you mean by jumper cables? Thanks!

you can replace those red jumpers

with "Arduino Jumper wires"

connected to any SPDT switch (center pin on PCB to center pin on switch)

if you need further assistance feel free to PM me to keep this thread module specific...


Hi Thermal,

Thanks a lot for your review of the SoundForce Dual Filter. Pity indeed of the jumper on the back to switch between LP & HP, otherwise it sounds great! :-)

Have fun with it and thanks a lot for letting us know, kind regards, Garfield.
