COMMOM parameters
COMMON: STRUCT (STRUCTURE) 1/2, 3/4
Specifies how tones 1 and 2 will be combined (Struct 1/2),
and how tones 3 and 4 will be combined (Struct 3/4).
Abbreviations shown for each type have the following
meanings.
- W/P: Wave/Pitch
- FILTER: Filter
- AMP: Amplifier
- B: Booster
- R: Ring Modulator
Range:
- TYPE 1: This is the most basic type. Tones 1 and 2 (3
and 4) are independent. Select this when you wish to
utilize the waveform of each tone without change, or
when you wish to layer tones to create a richer sound.
- TYPE 2: This type combines the two filters to
strengthen their characteristics. The AMP of tone 1 (3)
will control the volume balance of the two tones.
- TYPE 3: This type mixes the sound of tone 1 (3) and
tone 2 (4), applies a filter, and then applies a booster to
distort the waveform.
- TYPE 4: This type applies a booster to distort the
waveform, and then combines the two filters. The AMP
of tone 1 (3) adjusts the depth of the booster.
- TYPE 5: This type uses a ring modulator to create new
overtones, and combines the two filters. The AMP of
tone 1 (3) adjusts the depth of ring modulation.
- TYPE 6: This type uses a ring modulator to create new
overtones, and in addition mixes in the sound of tone 2
(4) and stacks the two filters. The AMP of tone 1 (3)
adjusts the depth of ring modulation.
- TYPE 7: This type applies a filter to tone 1 (3) and ring-
modulates it with tone 2 (4) to create new overtones.
- TYPE 8: This type applies a filter to tone 1 (3) and ring-
100
modulates it with tone 2 (4), and mixes the result with
the filtered sound of tone 2 (4).
- TYPE 9: This type passes the filtered sound of each
tone through a ring modulator to create new overtones.
- TYPE 10: This type passes the filtered sound of each
tone through a ring modulator to create new overtones,
and also mixes in the sound of tone 2 (4).
* With TYPE 2–10 selected, turning off one of the paired tones
will cause the other tone to sound as TYPE 1.
COMMON: BOOSTER GAIN 1/2, 3/4
When a Structure Type of "TYPE3" or "TYPE4" is selected,
you can adjust the depth of the booster.
This can be set for the pair of tones 1 and 2 (Booster 1/2) and
for the pair of tones 3 and 4 (Booster 3/ 4).
Range: 0, +6, +12, +18
Higher settings will produce greater distortion.
Booster
The Booster is a function that increases the input signal in
order to distort it.
In addition to using this for distortion, you can use the
waveform of one of the tones as an LFO to shift the other
waveform up and down, producing an effect similar to
PWM (Pulse Width Modulation). This is even more
effective when used in conjunction with the Wave Gain of
the WAVE/FXM.
-> "WAVE GAIN" (P. 89)
Ring Modulator
The ring modulator multiplies the waveforms of two
tones to create many new overtones that were not present
in either of the original waveforms (inharmonic
overtones). This is suitable for creating unpitched
metallic sounds such as bells.
COMMON: STRETCH TUNE
Select the stretch tuning curve. The selected curve will affect
the way that chords will sound.
Range: OFF, 1–3
