KBD TRACK
Adjusts the depth to which the cutoff frequency will
change according to the note number, centered at C3.
With a setting of 100, the change in cutoff frequency
will be proportionate to the change in pitch (1 octave in
pitch = 1 octave in filter frequency).
Note: unlike some of the other EXi, the PolysixEX
keyboard tracking does not include the effects of pitch
bend. This matches the behavior of the original
synthesizer. If desired, you can create the same effect
by using JS X as an AMS source for the VCF CUTOFF.

ATTACK
Adjusts the time from note-on until the maximum level
is reached.
This is scaled by MIDI CC# 73.
DECAY
Adjusts the time the EG takes to descend from the peak
to the sustain level.
This is scaled by MIDI CC# 75.
SUSTAIN
Adjusts the sustain level. The EG will stay at this level
until the note is released.
This is scaled by MIDI CC# 70.
RELEASE
Adjusts the time from the note-off until the level
decays to zero.
This is scaled by MIDI CC# 72.
Using separate EGs for the VCF and VCA
Unlike the original Polysix, the PolysixEX lets you use
separate EGs for the VCF and the VCA. To do so:
1. Set the VCA MODE switch to EG.
2. Set the VCF EG INTENSITY to 0.00.
3. Select the CUTOFF parameter.
4. In the Parameter Details panel for CUTOFF, select
EG2 as the AMS source.
5. Set the AMS Intensity as desired.
Now, the original EG will control the VCA, and EG2
will control the VCF.

Program P4: Main
4-1e: VCA
VCA stands for Voltage Controlled Amplifier, which is
the circuit that controls the volume of an analog
synthesizer.
MODE
This selects the main control source for the volume.
EG means that the volume is controlled by the ADSR
envelope.
You can also use EGs 2 or 3 to modulate the main
VOLUME parameter via AMS.
Gate means that the volume goes to maximum
immediately at note-on, and falls to silence
immediately at note-off.
ATTENUATOR
Adjusts the volume up or down by 20dB, in 0.1 dB
increments. This is separate from the main VOLUME
knob, below.
Also, unlike VOLUME, the ATTENUATOR is per-
voice, which means that you can modulate it via per-
voice AMS sources such as EGs, LFOs 1 and 2, key
tracking, etc.
4-1f: OUTPUT
PAN
[Random, L001...C064...R127]
This controls the stereo pan of the PolysixEX, at the
very end of the signal chain. A setting of L001 places
the sound at the far left, C064 in the center, and R127 to
the far right.
When this is set to Random, the pan position will be
different for each note-on.
You can also set this Pan parameter directly from the
Control Surface knobs. To do so:
1. Press the Control Surface Timbre/Track button.
2. Set the MIXER KNOBS switch to INDIVIDUAL
PAN.
3. Move Knob 1 to set the pan for EXi 1, and Knob 2
to set the pan for EXi 2.
You can also control pan via MIDI Pan (CC#10). A
CC#10 value of 0 or 1 places the sound at the far
left, 64 places the sound at the location specified by
the "Pan" parameter, and 127 places the sound at
the far right.
Note: you can select Random pan only from the on-
screen UI, and not from AMS, MIDI or the Control
Surface.
Note that this is a post-effects pan, while Unison
Stereo Spread is pre-effects:
Pan via Unison Stereo Spread -> PolysixEX Effects
(stereo) -> PAN knob (stereo in-out)
In the PolysixEX, PAN affects all voices at once, and so
it cannot be modulated by per-voice AMS sources such
as EGs or LFOs 1 and 2.
