Mystic Circuits ANA 2: Analog Boolean Logic Module

US Cross modulation powerhouse released      19/04/24

Mystic Circuits have just released the ANA 2 - an Analog Boolean Logic Module which processes multiple inputs with various mathematical rules to generate new, exciting, and downright bizarre signals. Described as a cross-modulation powerhouse its functions include mixing, clipping, logic, rectifying, cross-fading, voltage sampling, ring modulating, gate converting, bizarre wave shaping, and much more.

ANA 2 combines a wealth of functions normally seen in individual modules, shrunk down into one place and available together. Here's what they have to say:

ANA 2 is a cross modulation powerhouse that derives nine different analog logic operations in tandem from two input signals. Each input channel features a processing section that attenuverts, adds, or multiplies up to six inputs before being sent to the cross modulation circuits. 

At its core, ANA 2 is an Analog Boolean Logic Processor. Boolean logic normally takes two binary gate signals and combines them into a single gate signal based on mathematical rules. While the output of a normal boolean logic circuit is always a gate, analog boolean logic can both process and output any kind of voltage signal. This means that Ana works not only with gates but also modulation, note sequences, and even audio.

Whatever type of signal that you feed in is what you will get out of ANA 2. In fact, feeding ANA 2 a combination of different types of voltage signals will give you a weird blend between them. ANA 2 always gives you more than you put in, providing nine related but distinct outputs that can be derived from as little as a single voltage source or even no input at all.

Compared to its predecessor, ANA 2 has three new wave shaping outputs which add everything from simple mixing and multiplexing to completely unique non-linear wave shaping.  In addition, ANA 2 adds a pair of "multiplication" CV inputs which control a bipolar VCA acting on each main input.  Finally, ANA 2 is a big step up aesthetically with two LED level indicators for each channel as well as much cleaner panel art.  

ANA 2 Technical Specs:

  • Width: 6HP / Depth: 32mm 
  • Power Draw: +V 101 mA, -V 104 mA, 5V not used 


  • IN - Attenuverter Input (2) 
  • X - Multiply Input (2) 
  • + - Sum Input (2) 


  • MIN - Minimum : outputs the lowest voltage between both inputs.
  • MIX - Mixture : mixes both input channels together.
  • MAX - Maximum : outputs the highest voltage between both inputs.
  • XOR - Exclusive OR : analog XOR computation, behaves like a through-zero clipper. 
  • CUT - Bizarre Non-Linear Waveshaper : unique circuit that behaves like a cross between a wavefolder and a crossfader.
  • MAG - Magnitude : outputs the difference between both inputs.
  • STEP - Track and Hold : random voltage processor similar to other smooth/stepped random generators. 
  • SWAP - Switch : two input switch, switches between both inputs.
  • BOX - Comparator : three level square wave based on both inputs.

ANA 2 is priced at $225 and available now
