The ED102 lets you marry differing signal formats in to your system.


Among presently available music synthesizers there are, typically, two different types of control systems used for voltage control and trigger/gate control.


Voltage Control - The two most common formats are:-


  • Hertz/Volt
  • Volts/Octave


Trigger/Gate Control - The two most common formats are:-

  • S-Trig
  • V-Trig


The ED102 is ideal if you want to upgrade your synthesizer by adding on other synthesizer units having different kinds of keyboard control voltage and trigger signals. The built-in, fully adjustable log amp, anti-log amp, and trigger processor ensure complete system flexibility and compatibility between any presently voltage controlled synthesizer.  


The ED102 Hz/V/Oct Converter is designed for the purpose of connecting V/Octave synthesizers with Hz/V synthesizers. This sophisticated signal processor greatly enhances the performance possibilities of your synthesizer. Among presently available music synthesizers, there are two different types of control system used for the VCO (voltage controlled oscillator) and EG (envelope generator). One of these systems is used by Korg and Yamaha; the other is employed by every other synthesizer manufacturer.


The ED102 provides you with a way to change the control signals of one system into the control signals used in the other system. In this way, it acts as an interface so that any two synthesizers can be used together, provided that the synthesizers are equipped with the conventional input and output jacks for control voltage and trigger or gate signals
