Visual Markers: The back panel itself is characterized by its metallic grey top and black plastic bottom. Deciphering the Numbers
The M1 followed a sequential numbering system that reached significant milestones during its peak years.
Production Volume: Korg reached serial number 100,000 in November 1990.
Later Number Types: Later Korg serial numbers (post-1981) often followed a different format than the early 1966–1981 "yynnnn" year-based system. Before we look at the numbers themselves, it
Known Variations: Enthusiast databases, such as the ZASM Korg Serial Reference, track thousands of M1 serials, showing common sequences starting with "0" (e.g., 013537) up to "2" (e.g., 215725). Digital Alternatives: M1 Le and VST Product Codes Korg M1 (Retrozone) - Sound On Sound
For the hardware Korg M1 synthesizer , the serial number is typically located on the bottom casing of the unit. For the Korg M1 software plugin
or "M1 Le" edition, the serial number (product code) is provided via a black piece of paper included in the original packaging or via the KORG Software Bundle website after entering your hardware's PIN. Vintage Synth Explorer Forums Key Features of the Korg M1 , released in 1988, is widely considered the first true music workstation . Its defining feature is the AI (Advanced Integrated) Synthesis System , which combined several tools into one unit: PCM Waveforms
: It uses 4MB of high-quality sampled sounds (like the famous "M1 Piano") as the basis for its synthesis. Onboard Sequencer
: This allows musicians to compose entire multi-track songs directly on the keyboard without needing a computer. 8-Part Multi-timbrality

includes built-in digital effects like reverb and delay, which were revolutionary for synthesizers at the time of its release restore the original factory sounds Korg M1 - what model? - Vintage Synth Explorer Forums
The , manufactured from 1988 to 1995, is the best-selling digital synthesizer in history, with approximately 250,000 units produced. Because of this massive production run, serial numbers are the primary way for collectors and technicians to identify a unit's age and internal hardware revisions. 1. Finding the Serial Number
On the physical hardware, you can find the serial number in two main places: Before you sell your M1, or before you
Rear Panel Sticker: A small white or silver sticker typically located on the back of the unit, often near the MIDI ports or power input.
Original Documentation: For software-related versions (like the M1 Le), the serial number or product code is found on a black piece of paper or a KORG Software Bundle PIN card included in the original manual bag. 2. Serial Number Format & Dating
Korg transitioned its numbering system in 1983. For the M1 era (1988–1995), the serial numbers are strictly numerical (usually 6 digits) and do not contain embedded date codes like "YYMM". Instead, dating is determined by comparing your number to known production milestones:
The "First 100,000": Korg confirmed that 100,000 units were produced in the first two years. Serial #100,000 rolled off the line in November 1990.
Late Models: Higher serial numbers (e.g., in the 200,000+ range) indicate units manufactured between 1992 and 1995.
Early Models: Numbers below 050,000 are likely from the first year of production (1988–1989). 3. Why the Serial Number Matters
Verification: Buyers should verify serial numbers against production databases to avoid "M1-compatible" clones or mislabeled models.
Hardware Revisions: Different serial ranges may have different internal components, such as variations in the power supply or the internal CMOS battery (often a CR2032).
Software Registration: For digital versions, the serial number is required to associate an owner with a unique user account on KORG USER NET.
