Description
Product Description:
Immerse yourself in the melodic wonders of the Behringer Abacus Music Computer Eurorack Module, an ingenious gadget that redefines the boundaries of music creation. This innovative module is steeped in the tradition of the legendary analog processors of the 1960s, yet it bristles with modern capabilities tailored for today's adventurous musicians.
The Abacus is a sonic mathematician, conjuring a staggering array of linear, logarithmic, and exponential functions, each one triggered or continuous. With four CV inputs under your command, you can take full control of modulation depth and direction, allowing your creative genius to craft the perfect envelope.
From generating LFO signals that can span up to an astounding 25 minutes, to effortlessly integrating, inverting, or amplifying multiple functions, the Abacus truly is a universal tool for any music enthusiast. The potential to create lag, slew, or portamento effects, along with backward modulation and tempo manipulation, makes this module a must-have in any Eurorack setup.
Key Features:
- Mathematical sound processor inspired by revered models of the 1960s
- Capable of creating a wide variety of linear, logarithmic, or exponential triggered/continuous functions
- Four CV inputs for extensive envelope creativity
- LFO signals capable of reaching up to 25 minutes with rates as fast as 1kHz
- Ability to control modulation depth and direction for a personalized sound character
- Noteworthy note division and flam capabilities
- Fits seamlessly into most standard-size Eurorack setups
- LED activity indicators for easy module performance monitoring
- 2-channel function generator and CV processor
- Single outputs per channel plus outputs for sum, inverted sum, and logic OR
- Power consumption: 60 mA (+12 V) / 50 mA (-12 V)
