Roland SH-32 用户手册

Oscillator Sync synchronizes the wave output from OSC 1 to the 
wave output by OSC 2. When set to the OSC 2 pitch as shown in the 
figure, Oscillator Sync forces the OSC 1 to return to the start of the 
OSC 2 wave’s cycle, producing a complex waveform.

The Oscillator Sync effect is only applied to OSC 1; the OSC 2 
tone is not changed. If the Oscillator Sync effect is not 
sufficiently evident, raise [BALANCE] (toward the OSC 1 end). 
Moving [BALANCE] allows you to alter the ratio of the OSC 1 
sound, to which Oscillator Sync is applied, and the normal OSC 
2 sound.

• On the SH-32, 

. 

If you want to add a simple filter effect to a patch that uses 
Oscillator Sync, use INS-FX as the filter type (p. 64).

• Patches using Oscillator Sync are sounded only in mono. 

Furthermore, in Performance mode, they can be used only in 
Part 1. When used with Part 2 or 3, the Oscillator Sync function 
switches off automatically.

• When using Oscillator Sync, you cannot select a variation for the 

OSC 1 waveform. When you press [WAVE] to select the 
waveform group, an exclusive variation especially for synching 
is selected automatically.

• The Suboscillator function (p. 54), PWM function (p. 55) and 

Unison function (p. 62) cannot be used at the same time that a 
Patch using Oscillator Sync is active.

• In some cases, a reoccurring, cyclic noise may be audible in the 

low-frequency range in Patches using Oscillator Sync. This is a 
characteristic of the SH-32’s synching operations, and does not 
indicate any malfunction.

This creates sounds filled with numerous harmonics of different 
frequencies, but by using filters to pass only certain frequency bands 
while blocking other frequencies, you can also change the 
characteristics of the sound. By adjusting the filters in the FILTER 
section, you can change the output waveforms in a variety of ways, 
thus changing the sound.

Selects the type of filter.

When the Oscillator Sync function (p. 55) is in use, this is 
automatically set to “OFF” (filter cannot be used).

Turning [OSC 1X2 SYNC] on and then adjusting [PITCH 
COARSE] and [PITCH FINE] changes the sound to produce a 
variety of different tones.

This filter passes low-frequency 
harmonics under the cutoff fre-
quency. This is the filter that is 
most generally used, and it is ef-
fective for making sounds softer 
and mellower.

This filter passes harmonics with 
frequencies near the cutoff fre-
quency. This emphasizes the 
midrange. This works well for 
creating sounds with Particular 
sound qualities.

This filter passes high-frequency 
harmonics above the cutoff fre-
quency. It is effective for creating 
a brighter, sharper sound.

This filter boosts harmonics with 
frequencies near the cutoff fre-
quency. You can use this to create 
wah effects by employing an LFO 
to change the cutoff frequency 
cyclically.

No filter is used.
