Serial Number: Korg M1
A: There is no official Korg online database where you can type in a serial number and get an exact production date. However, a fantastic community resource is the independent project "Zen & the Art of Synthesizer Maintenance," which has compiled thousands of early Korg serial numbers, including many M1 units, from public sources like Matrixsynth. It is the best place to start your research.
, released in 1988, is one of the best-selling synthesizers of all time, with an estimated [22, 27]. Because of this massive production run, serial numbers range significantly, but they follow a few identifiable patterns:
Identifying your serial number range helps determine which internal hardware components your M1 contains. ROM Firmware Versions Korg M1 Serial Number
Serial numbers ranging from 001000 to approximately 040000 . These units feature the original, earliest firmware iterations and the distinct initial keybed factory setup.
In the pantheon of electronic musical instruments, few devices command the respect and historical significance of the Korg M1. Launched in 1988, this workstation synthesizer is the single best-selling synthesizer of all time, with over 250,000 units sold. For the modern collector, vintage synth enthusiast, or working musician using a 35-year-old piece of gear, the small, often-faded sticker on the bottom panel—the serial number—is a portal to a wealth of information. Far from a mere inventory tag, the Korg M1’s serial number is the key to unlocking the instrument’s manufacturing date, hardware revision, geographic origin, and even its potential for specific sonic characteristics or reliability issues.

Perhaps the most intriguing mystery for M1 owners is the unit that lacks a serial number entirely. This happens for several reasons:
Early serial numbers (1988) shipped with Firmware Version 1.0 to 1.3. These early versions contained minor MIDI bugs. Later serial numbers (1990 and beyond) feature Firmware Version 1.10 or higher, which stabilized MIDI overflow issues and improved system sysex dumps. Power Supply Variations
The first step in understanding the M1’s lineage is understanding the format of its serial number. Unlike the purely numeric sequences found on many competitors’ gear (like the Roland D-50), Korg employed an alphanumeric system for the M1. A typical serial number will look something like this: (an early Japanese unit) or 001650 (a very early production model).
