EXi: PolysixEX
PolysixEX Overview
The PolysixEX is a rich-sounding, easy-to-use, high-
polyphony virtual analog synth (up to 172 voices!). It
combines the features and sonic character of the classic
Korg Polysix (and the Legacy Polysix plug-in) with
many additional capabilities unique to the OASYS.
Features include:
• Korg’s proprietary CMT (Component Modeling
Technology)
• Oscillator, sub-oscillator, and 4-pole resonant
lowpass filter
• Dedicated chorus/ensemble/phaser effects
• Classic ADSR envelope, plus two multi-stage EGs
• Classic “MG” LFO, plus two multi-waveform LFOs
• Easy-to-use, sample-accurate arpeggiator
• Extensive AMS modulation, plus four AMS mixers
• Access to all standard EXi Program features,
including the Common LFO, Common Step
Sequencer, Key Track 1 & 2, KARMA, EQ, and
effects–as well as layering with any other EXi
(including using two PolysixEXs together!)
PolysixEX uses EXi fixed resources
The PolysixEX uses EXi fixed resources for its built-in
effects. These take up a small amount of processing
power, even if you’re not playing any notes.
Because of this, you can use only 16 PolysixEXs
simultaneously in a Combination or Song. If other EXis
with fixed resources are in use, the maximum number
of PolysixEXs will be reduced accordingly. Each EXi in
each Program counts towards the maximum; for
instance, a Program with two PolysixEXs counts as
two, not as one.
For more information, see “CX-3 & STR-1: Limitations
on EXi fixed resources” on page 326.
