Free delivery and returns on eligible orders. Review: 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 Review: 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.. ## Features - Algebraic sound processor modeled after Buchla's* models 257 and 281 from the '60s - Perform wide range of linear, logarithmic and exponential triggered or continuous functions - Generate musical envelopes or LFO signals up to 25 minutes and as fast as 1 kHz - Change the depth of modulation or even modulate backwards - Create musical events such as ramping up or down in tempo ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C4HT9QTQ | | Age Range Description | Adult | | Best Sellers Rank | 2,700 in Musical Instruments & DJ ( See Top 100 in Musical Instruments & DJ ) 90 in Synthesisers, Samplers & Digital Instruments | | Brand | Behringer | | Brand Name | Behringer | | Colour | Black | | Connectivity Technology | Eurorack power and CV/Gate, 3.5mm Audio Output | | Connector Type | 3.5mm Jack | | Country of Origin | China | | Customer Reviews | 4.6 out of 5 stars 83 Reviews | | Finish Type | Lacquered | | Headphones Jack | [POSSIBLE] headphones_jack | | Included Components | Eurorack power cable | | Instrument | Electronic keyboard | | Item Dimensions | 17.3 x 13.1 x 7.4 centimetres | | Item Dimensions D x W x H | 2.4D x 10W x 10H centimetres | | Item Type Name | tabletop synthesizer | | Item Weight | 300 Grams | | Manufacturer | Music Tribe | | Manufacturer Part Number | 0720-ACO86-001 | | Model Name | ABACUS | | Model Number | ABACUS | | Number of Keys | 4 | | Number of keys | 4 | | Power Source | Eurorack external power supply" gold "DC power supply | | Size | Einheitsgröße | | Skill Level | Advanced | | Skill level | Advanced | | Special Features | Portable | | Special feature | Portable | | Style | Modern | | Supported Software | Max/MSP | | UPC | 644216649303 | ## Product Details - **Brand:** Behringer - **Colour:** Black - **Number of keys:** 4 - **Skill level:** Advanced - **Special feature:** Portable ## Images ![Envelope Module ABACUS - Image 1](https://m.media-amazon.com/images/I/71MZV4-oAIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Functions 100% identical to Maths *by A***Y on 9 June 2025* It's a perfect clone of Make Noise Maths for a fraction of the price.
