Functions 100% identical to Maths
It's a perfect clone of Make Noise Maths for a fraction of the price. I have owned both at the same time and can say they function 100% the same. However Maths has larger knobs for the 4 attenuator inverters. One one hand this makes Abacus more fiddly to use and on the other hand it's easier to accidentally catch them on Maths. Pros and cons of each. Behringer build quality is totally fine, yes it's not as robust as some eurorack brands. But neither is make noise maths

Behringer Abacus.. Truly amazing value.
This is a truly amazing module set at a bargin price. The history of this device goes back to Buckla and true west coast synthesis.. There are other manufacturers versions available of this module, but this cannot be beaten on value for money..

Cost effective clone of Maths
Already have a Maths so this is my second…kind-of. No difference in functionality that I have found and much cheaper.

If you are broke and can’t afford Rampage or Math, this is a good option. It does the same thing and works really well. Good quality built as well.

So, many people are very upset that Behringer has copied an exhisting product, and I get that. However, if someone is trying to get into modular and can not afford the "real thing" then I feel they should have the option to get something affordable to them, in any case they were either going to but this one or nothing at all, so in the end is the company really missing out in that case? I feel the product is well made, though I would have liked to have the pots secured to the face plate, and also bigger knobs on the attenuverters. It does function exactly how one would expect, and even though it is a clone, it gets the job done. I have had the OG one in the past, but could not justify keeping it around, I picked one of these up mostly to see how it compared, and am impressed by the 1:1 function vs the OG unit. Do I think it is "right" to clone a product that is currently being sold? No I do not, but I also know how expensive Eurorack can be, and it can be a barrier to entry to people who really want to get into the "hobby" but are on a limited budget, and I think that is who these products are introduced for, right or wrong as it may be, they are probably not buying from MN anyway.

Make Noise Mathsクローン。 配置デザインは違っていて、野暮ったいぶん理解しやすいと思う。ただアッテヌバーターノブが小さすぎる。 それにしても本家は中古で4万ほどなのでコスパが良い。

Good module but definite learning curve to tweak to right settings and get good sound.

Fantastic Swiss Army knife with endless modulation configurations for your Eurorack setup. Just take a look at the many related YouTube videos for inspiration for using this must have gem.
