1. Introduction
Thank you for choosing Korg equipment. In order to get the
most out of your new MS-02, please read this owner's manual
carefully before use.
The Korg Interface MS-02 is designed for the purpose of
connecting Korg MS-Series synthesizers with other synthesizers
available throughout the world.
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 synthe
sizers are equipped with the conventional input and output
jacks for control voltage and trigger or gate signals.
2. Advantages of the Korg system.
In the Korg Hz/V system, the VCO oscillator frequency is
proportional to the control voltage. Other synthesizers employ
the OCT/V system, in which the oscillator frequency changes
one octave for every one volt (IV) change in the control
voltage. Since an increase of one octave means that the
frequency is doubled, each increase of one volt in the control
voltage means a doubling of VCO frequency. The problem
with the OCT/V system, used by every manufacturer except
Korg and Yamaha, is that it must employ a log amp in order to
double the frequency for each one volt increase in the control
voltage. Log amp circuitry is unfortunately very unstable
because of its sensitivity to temperature changes. This causes
so many problems that most professional musicians auto
matically assume that synthesizers always have unstable pitch.
When we developed our first Korg systhesizer, we decided that
such a circuit was entirely unsuitable for a musical instrument.
So, instead we invented our own unique, patented circuit in
which the keyboard output voltage (which is the VCO control
voltage) itself doubles for each one octave increase in pitch.
