[It] converts Korg’s Hertz/Octave to Volts/Octave and visa versa, making the sequencer compatible with other synths such as Roland, Arp Moog Sequential etc. These work very well and the pitch tracks nicely (I tested the SQ10 sequencing the MS50 and a Roland synth and the tuning was spot on). This sophisticated signal processor greatly enhances the performance possibilities of the MS-Series.
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 Korg MS-02 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.
The MS-02 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."
