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

 

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

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.

info INTERFACE converter
small black black box with MS series design.

The main panel features 6 knobs and 2 switches.

Front panel terminal connectors:

- 22 jack inputs for modular patching
- 6 knobs
- 2 function switches
- power on/off switch






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

cv gate - oscillator pitch

- the envelope trigger




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

hzv - 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 - the MS-02 just does that job.

log amp log amp

 



edit FUNCTIONS the Ms02 handles 4 main functions:

- 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.
- ANTILOG AMP exactly the LOG AMP contrary.
- ADDING AMP 2 channels +/-5 V can be added to incoming tensions.
- TRIGGER PROCESSOR 2 inverts the signal polarity that trigger the EG. If the controlled synth plays at note release, then use this polarity inverter.

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
