3. Producing sounds

Basic settings
Refer to "Normal Setting" and adjust the knobs.
Producing sounds by playing the keyboard
Press a keyboard key to hear the tone.
To adjust the volume, turn the VOLUME knob.
TIP Even if multiple keyboard keys are pressed, only one tone will be produced.
When two or more keys are pressed, the highest tone played will be pro-
duced.
Adjusting the knobs
Turn the CUTOFF FREQUENCY knob of the LOWPASS FILTER coun-
terclockwise to round off the sound. In addition, adjust the timbre by
using the OSCILLATOR 1 knob to change the waveform to the triangle
wave.
Patching to add variations to timbre
Refer to the following illustration and connect the patch cables.
The control wheel and momentary switch can be used. Adjust the con-
trol wheel and momentary switchs, and listen to the variations in the
timbre.
Refer to the original Owner's Manual and the setting chart to create
various sounds.
VCF setting
The VCFs (high-pass filter & low-pass filter) of the original MS-20 are
differentiated into the earlier and later filters, depending on the produc-
tion date.
Since the circuitry of these two types of filters differs, they have different
sound quality characteristics, although their frequency characteristics
are similar.
The MS-20 FS is equipped with both types of filters for you to select as
desired.
