EXi: MS-20EX
MS-20EX Overview
The MS-20EX is a flexible, semi-modular virtual analog
synthesizer. At its heart is a faithful re-creation of the
original Korg MS-20, including both its features and its
distinctive, often aggressive timbral signature.
To this core, we added features first introduced in the Korg
Legacy MS-20 plug-in. Then, we added significant patch-
panel modifications inspired by the MS-20’s big brother, the
MS-50, plus many other NAUTILUS-only enhancements.
Features include:
• Korg’s proprietary CMT (Component Modeling
Technology)
• Up to 40-voice polyphony
• Two oscillators (including ring modulation), noise
generator, and resonant, self-oscillating highpass and
lowpass filters
• Many modifications to the Patch Panel, including
separate access to VCOs 1 & 2, LPF, HPF, BPF, and
VCA
• Two new patchable 2-in, 1-out audio-rate mixers, for
combining and scaling audio and control signals
• Original MS-20 HADSR and DAR envelopes, plus four
additional multi-stage EGs
• Original MS-20 MG and sample-and-hold, plus four
additional LFOs
• AMS modulation of all original MS-20 parameters,
along with four AMS Mixers
• Live audio input
• External Signal Processor, with dedicated filters,
triggering, and audio-to-CV conversion
• Access to all standard EXi Program features, including
the Common LFO, Common Step Sequencer, Key Track
1 & 2, Arpeggiator, EQ, and effects–as well as layering
with any other EXi (including using two MS-20EXs
together!)
MS-20EX uses EXi fixed resources
The MS-20EX takes up a very small amount of processing
power, even if you’re not playing any notes on the keyboard.
This amount is around 1/12 that of the CX-3, but if other EXi
are using large amounts of fixed resources, the number of
MS-20EX that you can load may be limited. Each EXi in
each Program counts towards the maximum; for instance, a
Program with two MS-20EX’s counts as two, not as one.
For more information, see “CX-3 & other EXi: Limitations
on EXi fixed resources” on page 380.
