Korg MS-10 is an analogue synthesizer created by Korg in 1978.[1] Unlike its bigger brother (The MS-20), the MS-10 only has one VCO. It is monophonic and has 32 keys.

The MS-10 is well known for its huge sounding electro bass sounds.

Audio path[edit]


The MS-10 has one VCO with 4 waveforms: triangle, sawtooth, pulse, and white noise.


The MS-10 has the same low pass filter as the MS-20


There is a simple single transistor VCA. The amplitude of the VCA can be controlled by the envelope generator.


Modulation generator[edit]

The MS-10 has one LFO, labelled "modulation generator". It has two controls (rate and shape) and two outputs (pulse and sloped).

The shape control affects the pulse width and the shape of the sloped output. At midway, the pulse width is 50% and the output is a triangle wave. The pulse output is available through the patch panel and useful for triggering the S&H or the envelope generators. The sloped output also has a dedicated jack on the patch panel. Without patch cables modifying the signal, it can modulate the frequency of the VCO and the filter cutoff.


There is one envelope generator with controls for Hold, Attack, Decay, Sustain and Release.


Although the MS-10 has normalized connections, they can be modified with patch cables. This allows the LFO to modulate the pulse width (which is called pulse width modulation, or PWM) of the VCO or the amplitude of the VCA. It also has a noise generator with white and pink noise outputs, CV in and out, and an external signal input (not to be confused with the "External Signal Processor" of the MS-20).

Compatibility With Other Synths and Modules[edit]

The MS-10's VCO uses linear voltage control (Hz/Volt) and a converter is needed for V/Oct CV control. The rest of the synth will work with standard synth modules.
