Ana is an analog logic utility that can perform a wide variety of functions. At its core Ana is a set of four diode logic circuits and signals derived from those circuits. However, Ana differs from other logic modules in that it can process variable analog signals and give a variable analog output instead of just binary on-off gates. Use Ana with one input and gain six outputs all related to that input, or feed Ana with two signals and get six cross-modulation processes. With two input controls which work as either attenuverters, offsets or static values Ana can process audio, sequences, modulation and even video in a huge variety of ways.

Features:

ANA is a utility module comprising six functions that combine two inputs. These functions are:

• MIN – compute the minimum of the two input voltages
  
  
• MAX – compute the maximum of the two input voltages
  
  
• VCA – compute the XOR, or multiplication the two input voltages
  
  
• MAG – compute the difference between the two input voltages
  
  
• STEP – perform a track and hold based smooth/ stepped process from the two inputs
  
  
• BOX – perform a bipolar comparator process resulting in a 3 level square wave
  
  

‍The front panel controls are used to attenuvert or offset the input signals depending on how ANA is patched:

• Patching a signal into either IN1 or IN2 will make the corresponding knob function as an attenuverter
  
  
• Patching a signal into either SUM1 or SUM2 will make the corresponding knob function as an offset
  
  
• Patching into both inputs will attenuvert the signal patched into either IN1 or IN2 and add the signal patched into either SUM1 or SUM2
  
  
• Leaving all inputs to a channel unpatched makes the corresponding knob a static offset
  
  
• The attenuverters are able to boost an incoming signal by a factor of 2
  
  

ANA lends itself to a wide variety of functions, many of them performed simultaneously. Here is a short list of them:

• Process CV with gain and offset.
  
  
• Multiply signals as a through-zero VCA with unique character.
  
  
• Add harmonics by rectifying a signal.
  
  
• Create pseudo random sequences.
  
  
• Distort incoming signals under voltage control
  
  
• Compute Boolean logic on gates or continuous voltages.
  
  
• Extract Gates and sequences from modulation signals.
