Hello all,

I guess this is the usual newcomer request for helpful advice thread.
I am a complete amateur with a developing passion for synths. I have recently ordered the Neutron and look forward to cutting my teeth with it when it arrives.
While I anxiously await its arrival I discovered this site and thought I'd have a play and hopefully learn a bit along the way. I have the Moog model 15 app and thought I'd have a crack at replicating what I could using the Behringer system 55 range of modules.

There seems to be a few gaps with what Behringer has on offer and what is on the IOS app so I'm unsure how practical this set up would be.
I'm definitely interested in putting something like this together once I know how it will all work and the price being as attractive as it is for the Behringer modules should allow me to just get away with it without the Wife getting too angry with me ;)

Thanks all and I look forward to hearing some thoughts :)


Hi Padmasan,

Are you sure that all those Behringer modules are nicely Eurorack compatible? Yes they fit into a Eurorack but how about the compatibility? I am not so sure and would check that first.

Behringer - Neutron is a great device but for other modules I would check other brands if I would be you, at least to start with. Consider a mixture of different brands to give you a few different ideas of what is possible.

If you insist on using Behringer modules then go to your local dealer and have it tested there first.

Good luck and kind regards, Garfield Modular.

Hi GM and thanks for the reply.

I must be missing something. All of these modules are described as Eurorack. What must they be compatible with exactly?

Is it a voltage spec or firmware?

I was under the impression these modules were universal

School me please :)


Hi Padmasan,

The Behringer 900 series are based on the Moog's System-55 and if I am not mistaken, since it's a, and I am quoting here Behringer.com website:

Authentic reproduction of the circuitry from the "Modular 55, 35 & 15" Series

You might have it so authentic that you need to work with s-triggers. But I am not too deep into that kind of "old" stuff. There are similar discussions already, please refer here within this forum to:

https://www.modulargrid.net/e/forum/posts/index/8645
https://www.modulargrid.net/e/forum/posts/index/8162

But at those times the Behringer modules weren't there yet. I am not 100% sure but I would be careful with those 900 series. At least check it out in more details (sorry I didn't had the time to 100% check this out yet).

Behringer also has the 100 series modules these are Roland 100m based modules, if I am not mistaken those are okay but better have those double checked too.

So generally, you are right with Eurorack, as long as it is a Eurorack module it should be compatible with the rest of the Eurorack modules unless it's a replica of some (old) sort (and that's here the case), then you better be careful and have this checked out very well.

Best is still to go to your local dealer and test a few of those 900 modules in combination with classic stuff like Doepfer, Intellijel, Erica Synths, etcetera.

Or perhaps one of the more "compatibility experts" can tell with 100% certainly if those 100 & 900 series of Behringer can be used 100% compatibly?

Good luck and kind regards, Garfield.

Hi Padmasan,

Sorry, I forgot to tell, check out the Behringer 961 Interface module, that should be a kind of indicator of the above ;-)

Kind regards, Garfield.

Hi Garfield,

Thanks for taking the time to explain this to me. It's very generous of you :)
