When the M50 arrived in 2008, Korg positioned it as the more affordable sibling to the M3, stripping away some complexity while keeping the core sound engine that made their workstations legendary. It's essentially a streamlined performance and production tool that doesn't pretend to be something it isn't, which is exactly why it found its audience among gigging musicians and bedroom producers who wanted serious synthesis power without the bloat.
The M50 runs on Korg's Enhanced Definition Synthesis engine with 80 voices of polyphony and 256MB of PCM data shaped into 608 programs and 384 combinations right out of the box. You get two stereo oscillators per voice with four-way velocity switching and crossfading, up to four multimode filters per voice running in parallel or series with 24dB slopes, and five envelope generators plus five LFOs for deep modulation possibilities. The Alternate Modulation Source system is particularly clever, letting you blend and process multiple modulation sources with multiplication and quantization before routing them anywhere you want. Effects-wise there are 170 algorithms across five insert slots, two master effects, and a total effect, giving you plenty of sonic shaping without individual outputs to worry about.
The interface centers around a 320x240 touchscreen that handles editing and navigation without feeling cramped, paired with a quick dial and intuitive banking system. Available in 61-key and 88-key versions, the 61 uses a semi-weighted Natural Touch keyboard while the 88 features Korg's Weighted Hammer Action 3 graded action. The 16-track sequencer can hold 128 songs with 210,000 note capacity and 480ppqn resolution, and dual arpeggiators let you run everything from traditional patterns to complex polyphonic phrases and drum grooves simultaneously. The whole package weighs just under 15 pounds in the 61-key version, making it genuinely portable for a workstation.
Players have consistently praised the M50 for its intuitive workflow, excellent sound library, and the value proposition it delivers.
