A nice Maths clone at a great price. So nice this is my second one. Can do alot with two and some interesting Abacus only voice with that two. As well all the wonderful things a single one can do.

This module packs a lot of functionality: quad attenuverter, fixed CV source, function generator... It handles everything from simple utility tasks to creative modulation and control signal processing. That's well documented in countless videos and write-ups about the Make Noise Maths module.

As many already know, the Behringer Abacus is essentially a 1:1 clone of Maths, which itself draws from classic Serge and Buchla designs.

That said, this is not quite Maths. There are a few cost-cutting compromises that may affect durability and usability in the long run:

Jacks are PCB-mounted only – They aren't secured to the front panel, so all mechanical stress from patching is transferred directly to the circuit board. Over time, this could lead to PCB damage.

Small, awkwardly placed attenuverter knobs – The four inner knobs are cramped and smaller than ideal, which makes them a bit uncomfortable to use.

I'll admit I felt a little conflicted purchasing what's essentially a legal knockoff from a giant like Behringer—but it's the only way I could afford this kind of functionality.

Bottom line: If you're on a tight budget, it's hard to beat this deal. If you can afford the original, Maths is still the better choice.

As always, Sweetwater's service was excellent, and the price was more competitive than other major retailers.

Exactly like Math's for a way better price. I highly recommend it.

Fantastic backwards/forwards sound shaping module. I'm starting to enjoy the 60's and 70's synth sounds this unit produces. Well worth the price and not hard to patch in and roll with the rest of your modules. Very useful if you're just starting out like me with say for instance, a midi keyboard, oscillator, amp, envelope generator, eq/mixer and such. It can take these modest and not so modest noise makers to a whole new level. Love it.

I have the Maths module, wanted another one, saw this and though for $ I will try it, IT WORKS JUST AS GOOD AS MATHS, but the knobs are slick, small, and the connectors feels cheap, thats what I would exspect on a module that costs $ less than the Maths. I wanted to ad more LFO's to my setup, and I like having modules that do more than one thing. Will it last? if your not ruff with it, I think it will last fine. I am replacing my knobs with the euro style ones, they are easier to adjust than the slick ones on it.

Well someone DID think of it -- it's called MATHS by Make Noise. But yeah, this builds on that original module based on , indeed, Buchla concepts and then some

Just started playing with this module and it's immediately apparent what a great value this arithmetic control voltage generator is. I never actually used the Buchla, but attended a live Seastones performance by Ned Lagin, Phil Lesh and crew so I can appreciate the usage for both retro and drone/house styles of electronic music production, both live and studio. Behringer has done it again!

I have Maths too and glad to pick this up for a mere $ for use in another rack.
Capitalism at it's very best.

Behringer innovation at it's finest. They did it ...again!

Why didn't anyone else think of this first?
