Introduction to the M50
Main Features
EDS (Enhanced Definition Synthesis)
The M50 is based on the same EDS (Enhanced 
Definition Synthesis) found in the M3, delivering rich 
and vivid sound.
Each voice has two oscillators (allowing four-stage 
velocity switching/crossfading/layering) and can use 
up to eight (stereo) multisamples, up to four filters 
(two filters per oscillator with four modes and four 
routings), two amps, five LFOs, and five EGs, all 
available simultaneously.
The oscillator section provides a total of 1,077 
multisamples (including seven stereo multisamples) 
sampled at 48 kHz, as well as 1,609 drum samples 
(including 116 stereo drum samples), giving you a total 
of 256 Mbytes of sample data (when considered as 16-
bit linear data). These PCM sources are available for 
use in the oscillator section via four-way velocity 
switching/crossfading/layering to create a broad 
range of expressive, high-quality sounds.
The filter section - so vital to creative sound design -
lets you simultaneously use two filters for each 
oscillator. Filter types include low-pass, high-pass, 
band-pass, and band-reject (notch). You can use the 
two filters in any of four routings: single, serial, 
parallel, or 24 dB mode.
The amp section provides a driver circuit that adds 
edge and character to the sound.
The key tracking generator allows the filtering to vary 
according to the keyboard range; you can apply subtle 
filtering for convincing simulation sounds, or 
aggressive filtering that produces drastic changes in 
filtering as you play up or down the keyboard.
The M50 takes advantage of its lavish amount of 
available processing power to produce ultra-fast and 
ultra-smooth EGs (envelope generators) and LFOs. 
EGs allow you to specify how the sound develops over 
time, from its onset to its end. Each EG stage (attack, 
decay, slope, and release), gives you detailed control 
over how the tone and volume change over time, and 
make it possible to program anything from simulated 
acoustic sounds to vintage synthesizer sounds with the 
utmost detail. 
Korg’s AMS (Alternate Modulation Sources) provides 
a rich array of modulation possibilities, with 50 
different modulation sources that you can use to 
control the sound in complex ways. The M50 takes this 
classic Korg feature even further, via the AMS Mixers. 
These let you create even more detailed modulation 
designs by mixing two modulation sources together, 
multiplying one modulation source by another, or 
modifying the shape of the modulation source in 
various ways.
Programs, Drum Tracks, and each of the sixteen 
timbres/tracks has its own three-band EQ, letting you 
make detailed adjustments to the tonal character.
To let you shape the final character of the overall 
sound, the effect section provides up to five insert 
effects, two master effects, and one total effect. In 
addition to delay and reverb, a total of 170 high-quality 
effects are available, including modulation-type effects 
such as chorus, phaser, and flanger; dynamic-type 
effects such as compressor and limiter; and amp-
modeling effects generated using Korg’s proprietary 
“REMS” modeling technology. There are also two 
common LFOs that can be shared between different 
modulation effects. For example, you can create 
sophisticated effects such as using a single common 
LFO to synchronize the modulation frequency of a 
phaser and a flanger used on different timbres. Effect 
dynamic modulation (Dmod) lets you control the 
sound or the effects in a wide variety of ways, ranging 
from the subtle to the dramatic.
Drum Track function
The Drum Track function lets you listen to drum 
patterns while you construct the outline of your song. 
You can easily select the M50’s built-in patterns or 
create your own, and then start the pattern from a 
specified region of the keyboard or by playing a 
velocity higher than a specified threshold.
This function is also useful for anything from realtime 
performance to generating sketches for song 
production
Enhanced Sequencing
The heart of any music production system is the 
sequencer. The M50’s sequencer lets you record 16 
MIDI tracks, up to 128 songs, and 210,000 notes. With a 
high resolution of 1/480, every timing nuance of your 
performance will be captured accurately. You can use 
the Cue List function to create your song section by 
section and then play it back as a medley in the form 
you want.
Auto Song Setup function
Auto Song Setup takes care of many assignment and 
routing tasks automatically, so that the sequencer is 
armed with programs, combinations, effects, drum 
track and arpeggiator settings making it easy to create 
the basic tracks at the core of your song.
Dual polyphonic arpeggiator
Five preset arpeggio patterns (UP, DOWN, ALT1, 
ALT2, RANDOM) and 1,028 user arpeggio patterns are 
built-in.
In addition to providing conventional arpeggiator 
functions, the polyphonic arpeggiator of the M50 can 
respond to the pitches or timing at which you play the 
keyboard, and produce a diverse range of chords or 
phrases. This can be used to play a variety of drum 
phrases (the “Fixed Note Mode” is ideal for drums), 
bass phrases, or guitar and keyboard backing riffs. The 
arpeggiator is also effective for use with subtly moving 
pads, synth sounds, or sound effects.
