EXi: PolysixEX
312
Pulse waveform at different widths
PWM SPEED [0.00...10.00]
The PolysixEX has an LFO dedicated to pulse width
modulation (PWM). This adjusts the speed of that
LFO. Note that this applies only when the
WAVEFORM is set to PWM.
The dedicated PWM LFO is shared between all the
PolysixEX voices, similar to the Common LFO.
If you’d like more flexible PWM, including per-voice
modulation, you can use AMS to modulate the
PW/PWM parameter directly.
SUB OSC [2OCT, 1OCT, OFF]
The VCO includes a sub-oscillator. You can set this to
sound either one or two octaves below the main
oscillator, or turn it off completely if desired.
2OCT: the sub-oscillator will sound at two octaves
below the main oscillator.
1OCT: the sub-oscillator will sound at one octave
below the main oscillator.
OFF: disables the sub-oscillator.
4-1b: MG (Modulation Generator)
The MG is shared between all PolysixEX voices,
similar to the Common LFO. For per-voice
modulation, use LFO1 or 2 instead.
The MG is available as an AMS source throughout the
PolysixEX, in two different versions: MG is the
unaltered MG signal, and MG + Delay is at 0 until the
programmed DELAY time has elapsed.
TEMPO SYNC [Off, On]
Touch the text/LED area to turn TEMPO SYNC on
and off.
On (LED lit): When TEMPO SYNC is On, the MG
synchronizes to the system tempo, as set by either the
Tempo knob or MIDI Clock. The MG speed is
controlled by the combination of the BASE NOTE and
FREQUENCY/TIMES parameters, below.
Off (LED dark): When TEMPO SYNC is Off, the
FREQUENCY/TIMES knob determines the speed of
the MG, and the BASE NOTE setting has no effect.
This parameter is not modulatable via AMS.
KEY SYNC [Off, On]
If this setting is ON, the phase is reset for the first note-
on in each legato phrase. Subsequent notes in a chord,
or notes played legato, do not cause the phase to be
reset.
This parameter is not modulatable via AMS.
BASE NOTE [1/1...1/32]
When TEMPO SYNC is ON, this sets the basic speed
of the MG, relative to the system tempo. The values
range from a 32nd note to a whole note, including
triplets. This value is then multiplied by the
FREQUENCY/TIMES knob, below.
When TEMPO SYNC is OFF, this parameter has no
effect.
This parameter is not modulatable via AMS.
FREQUENCY/TIMES [0.00...10.00/16...1]
If TEMPO SYNC is OFF, this controls the frequency of
the MG.
If TEMPO SYNC is ON, this multiplies the length of
the BASE NOTE. For instance, if the BASE NOTE is
set to a sixteenth note, and Times is set to 3, the MG
will cycle over a dotted eighth note. Note that higher
values mean a faster MG.
DELAY [0.00...10.00]
Adjusts the time from note-on until the MG is heard.
Note that this affects only the routing selected by the
MODE parameter, below; the VIBRATO always uses
the un-delayed MG signal.
LEVEL [0.00...10.00]
Adjusts the depth of the effect produced by the MG.
MODE [VCA, VCF, VCO]
Selects whether the MG modulates the amplitude
(VCA), the filter cutoff (VCF), or the pitch (VCO).
4-1c: VCF
CUTOFF [0.00...10.00]
This controls the cutoff frequency of the 24dB lowpass
filter. Sounds above this frequency are removed,
making the timbre darker.
This is scaled by MIDI CC#74.
RESONANCE [0.00...10.00]
Resonance emphasizes the frequencies around the
cutoff frequency.
When this is set to 0, there is no emphasis, and
frequencies beyond the cutoff will simply diminish
smoothly.
At medium settings, the resonance will alter the timbre
of the filter, making it sound more nasal, or more
extreme.
At very high settings, the resonance can be heard as a
separate, whistling pitch. Near the maximum setting,
the filter will self-oscillate.
RESONANCE is scaled by MIDI CC#7.
EG INTENSITY [–5.00…+5.00]
Specifies the depth and direction to which the EG will
affect the cutoff frequency.
This is scaled by MIDI CC#79.
