Korg microKORG (2002)

A gooseneck mic, a 37-key keyboard, and an 8-band vocoder - the budget synth that ended up in everyone's rig.

Overview

The microKORG arrived in 2002 as a compact synthesizer/vocoder built around analog modeling synthesis. That is Korg's term for generating tones digitally while emulating the behavior of classic analog circuits. The pitch was simple: a small, affordable, dance-friendly instrument with a real vocoder on board, not a preset box with a microphone bolted on as an afterthought. Korg shipped the gooseneck microphone and power supply in the box, which shows how central the vocoder was to the concept.

Plenty of budget synths came and went. The microKORG stuck. WIRED, reflecting on the instrument's long run, called it one of the best-selling synthesizers of all time, and Korg's own materials describe it as one of the company's top-selling instruments. It remains a recognizable sight on stages and in home studios, which is rare in this price bracket. Sound On Sound (January 2003, p.110), reviewing the synth on release, noted the connection set as a full complement of MIDI sockets - In, Out and Thru - alongside two sets of audio inputs and a headphone socket. It also flagged the absence of pedal connectors and the single stereo output as reasonable omissions at the price.

The engine underneath is closer to Korg's MS2000 than the price tag suggests. The microKORG carries the same DSP synthesis as the MS2000B - two oscillators - but with a much larger waveform selection. Vintage Synth Explorer characterized it as a retro-looking, compact take on the MS2000's analog modeling approach. That's a fair frame: a scaled-down, battery-capable version of a bigger instrument's voice architecture, not a toy with a vocoder stapled to it.

Key Features

Advanced 8-Band Vocoder with Gooseneck Mic

The vocoder is the microKORG's calling card. It's an 8-band design, with eight frequency bands of the incoming voice signal shaping the synth's output. The microphone is top-mounted on a gooseneck and included with the instrument, so the classic robot-voice effect works the moment you unbox it. There's also a dedicated audio input, so the vocoder can be driven by external sources rather than only the stock mic.

Dual Oscillators with DSP Synthesis

Two oscillators per voice, running Korg's analog modeling engine. Retailers describing the synth have called it a true synthesizer with an analog modeling tone generator and a powerful-sounding oscillator section. The MS2000B comparison is the useful reference point: same DSP synthesis, more waveforms to choose from.

Four Filter Modes, Including a 4-Pole Lowpass

The filter section offers four modes: a 12 dB (2-pole) lowpass, a highpass, a bandpass, and an additional steeper 24 dB (4-pole) lowpass. The 4-pole option is the one that gets used. It's the classic warm, resonant sweep, and having it on a synth at this price was not a given in 2002. Korg's marketing described the filter as "knife-sharp," which is fair when you push the resonance.

128 Programmable Sounds

128 program locations, all user-writable. For a compact instrument aimed at dance and electronic producers, that's enough room for a set's worth of patches without constant overwrites.

37-Key Keyboard and Battery Operation

The keyboard is 37 keys, small enough to make the microKORG portable. It runs on batteries as well as the included power supply, which made it a fixture in live rigs and bedrooms alike. At 2.2 kg and measuring 524 mm wide, 232 mm deep, and 70 mm tall, you can carry it under one arm. Connectivity is straightforward: stereo output, audio input, and MIDI In, Out and Thru. Sound On Sound (January 2003, p.111) noted that despite the small keyboard, the unit can't be rackmounted. That's a limitation for studio users who wanted to slot it into a rack alongside their other gear.

Historical Context

The microKORG was introduced in 2002, following the success of Korg's Electribe grooveboxes. It was marketed as an affordable, dance-friendly instrument, and that positioning landed. It became one of Korg's top-selling synthesizers and, by WIRED's accounting, one of the best-selling synthesizers of all time. The product family includes the microKORG S, a later version of the original, and the microKORG XL, which is a separate model rather than a direct revision. Korg has revisited the formula several times over the years, and WIRED observed that those later attempts haven't caught on the way the original did.

Collectibility & Value

The microKORG's used market is active rather than precious. Recent eBay completed sales in the fact sheet's data run from $217 to $454, with a median of $330 across 170 sales over a twelve-month window. A summary box dated October 2026 lists a high of $550, a low of $60, and a latest sale of $317, with roughly 21 units moving per month. That volume says people buy these to play. Earlier data points are lower: as of December 1, 2022, a microKORG with a carrying case was listed at $350, and the instrument was commonly found for under $200, with the best prices seen from $220.

Buyers should check which microKORG they're actually looking at, because the family shares a name. Listings for the microKORG XL, XL+, S, and the black BKBK limited edition all show up in the same searches. Recent sold examples include an XL at $295, an XL+ at $500, a BKBK limited at $390, and an S at $346, plus an XL bundle listed at $362. Those are different instruments, and their prices shouldn't be read as the original's. The fact sheet contains no information on common failures, maintenance requirements, or spare-parts availability for the original microKORG, so nothing can be said about long-term reliability here.
