Korg MS-02
Cv/trigger interface (197x)

 

Analog synth interface converts synthesizers tension controls between Hz/V and 1 V/Oct and vice versa.

info INTERFACE converter
small black black box with traditional MS series design. The main panel features 6 knobs and 2 switches.

Front panel terminal connectors:
- 22 jack inputs for modular patching






cv CV FOREWORD
before the Midi system, analog ynthesizers and other musical gears could played be externally played or sequenced by an analog control system: the Control Voltage with a trigger.

The CV/Gate combo is basically composed by 2 tensions that controls:
1- oscillator pitch
2- the envelope trigger.

cv
CV STANDARDS there are 2 main CV standards with different scale values:

- 1 V / oct
linear tension and is used by Roland, Sequential Circuits (e.g Sequential Pro1) , Arp (e.g Arp Odyssey), Oberheim and Moog (e.g Minimoog)

- Hz/ V
logarithmic and used by most of Korg machines (e.g MS-20) and Yamaha (e.g cs-15)

tip
CONVERTER the Hz / V system is technically more precise but defintively less common than 1V/Oct, so for for linking different systems a converter is needed and guess it: the Ms02 just does that job.



log amp




edit FUNCTIONS
the Ms02 handles 4 main functions:

edit- LOG AMP changes Hz/Volt tension to 1V/Oct - you have to plug the signal to IN, calibrate the Lowest pitch with FREQUENCY and higher with WIDTH so both scales are matched.

edit- ANTILOG AMP exactly the LOG AMP contrary.

edit- ADDING AMP 2 channels +/-5 V can be added to incoming tensions.

edit- TRIGGER PROCESSOR 2 invert the signal polarity that trigger the EG. If the controlled synth plays at note release, then use this polarity inverter.

comment

REVIEW "Fascinating vintage item like all Ms series. I tried some conversions between various calibrated synths and not all were really satisfactory.Not all combinations seem to be working. Try it before."

manual manual
-ms series related -hard to find
-collectable - does not work really well with some synths
