CV / Gate interface for Korg Ms-20 or Behringer K2
This hand made interface has been designed to allow V/Oct CV and gate control of the Behringer K2 or the Korg MS-20 and has been tested on both.
V-TRIG or gate signals sent to the unit’s V-TRIG in are converted to S-TRIG format at the output and can be sent directly to the TRIG-IN of the K2 or MS-20
Whilst the CV inputs of these synths do not work with the standard 1V/Oct CV control, the modulation inputs do. However, they are very difficult to calibrate which is where the CV part of this interface helps. Just plug it into one of the modulation inputs and turn the corresponding modulation level to maximum. It is then very easy to get perfect V/Oct control using the fine voltage adjustment on the interface. All interfaces have been calibrated using a K2 Total-Ext input, but should you need to adjust the calibration a simple guide is included. You will ideally need a frequency meter or app (there are some free ones available).
The CV part of the interface is completely passive, and the tiny amount of power required to run the trig circuit is derived from the incoming gate signal, so the interface does not require a power.
The Trig side of the interface can also be used to trigger the sample & hold or the EG-1 of the K2 / MS-20.
Note: please allow your synth to warm up for at least 15 mins before attempting any changes to the calibration of the interface.
