Korg MS-20 mini

Many of the iconic brands in this industry have attempted to release modern versions of synthesizers from their vintage series of the past, and most have failed to do it right (we're looking at you Roland!). Until now, that is.

Korg's most famous and coveted monophonic synthesizer is the MS-20, first introduced in 1978, and it has been reborn as the MS-20 mini. Korg enlisted the same engineers who designed the original MS-20 to recreate it in a body that is smaller by 86% of the original size, but looks and sounds the same. This is an authentic reproduction of the original specifications of the MS-20, and it delivers the same powerful sound, from deep, growling basses to crisp, rounded leads.

The MS-20 mini has the exact same synthesis as the original: two analog oscillators with ring modulation, and envelope generators with delay and hold. The VCA (Voltage Controlled Amp) maintains the original basic design, but has been modified to produce less noise.

Best of all, the powerful MS-20 filter is alive and well in the MS-20 mini, providing both high-pass and low-pass with peak/resonance. This is the same reincarnated version of the filter that was also used on Korg's Monotron and Monotribe. Of special note, half-way through the production lifecycle of the original MS-20, the filter circuit was changed; the MS-20 mini uses the earlier KORG35 filter circuit which has been considered the better version of the two.

The ESP (External Signal Processor) allows external audio signals to be used with the MS-20 mini, just as the original allowed. For example, the pitch or volume of an external audio source could be used to control the synthesizer. The distinctive and flexible patching system enables the creation of complex sounds by allowing the rerouting of both modulation and audio (both the internal oscillators and external audio). Flow-charts printed on the front panel (meticulously reproduced from the original) help users of any experience level understand how to route signals and produce a variety of sound possibilities.

The most obvious difference between the Mini and the original, is the size. It is 86% of the original size, and the 37 keys of the keyboard are mini-keys. Patch cables/plugs have also been shrunk down from 1/4" phone-plugs to 1/8" mini-plugs. The other major difference is the MS-20 mini is equipped with a MIDI IN jack for receiving note messages, and a USB-MIDI connector that can transmit and receive note messages from a computer and/or external sequencer. It should be noted that the MS-20 mini only responds to note messages; controller changes were excluded from the MIDI spec because they would not give you the smooth, un-stepped parameter changes associated with actual hands-on knob tweaking.

Korg also packaged the MS-20 mini in a manner that replicates the original, and included the original MS-20 owner's manual and settings chart. Buyers of the MS-20 mini are not getting a run-of-the-mill Korg synthesizer exploiting the namesake of its vintage Icons. The MS-20 mini is an MS-20, inside and out, with the added MIDI and USB functionality needed to make it talk to modern studio equipment right out of the box. Amazingly, it lists for only $599 USD!

El pequño Ms-20 mini es una verdadera maravilla a lo que a sonido se refiere. la calidad de construccion es un poco escasa. Pero en genaral veo que es una tonteria gastarse un dinero en el ms original teniendo este, nuevo y mas barato.

*Finally* got mine today. Fifteen weeks after I ordered it - yet *totally* worth the wait. The mini-keys aren't optimal, but they're not small enough to really be a problem. The headphone output seems noisy, but the line-out is clean. Build quality is solid. Key action is light but good; not loose or bouncy. The sound is *excellent.* I can't speak for its accuracy to the original (never played one,) but on its own merits it's great; smooth modulations, an unusually buzzy triangle wave for VCO 1, weird filter character, squelchy resonance and howling self-oscillation. What a great piece of kit!

If anyone wants to trade their Mini plus cash for my ORIGINAL near-mint MS20 (first version Korg35 chips), let me know! Or if you just want to outright buy it too...

The first 2 osc real VCO vintage design anywhere near this pricepoint since the early 80s. Korg has taken the mantel from Roland here (not that Roland is in the analog market anymore anyhow). The Volcas are also amazing.
