@ vco
Generally called vibrate, VCO produces pitch changes in accordance with voltage. The vibration effect grows deeper
when the lever is raised.
@
VCF
Generally called wah-wah, VCF changes the cut-off frequency according to voltage. By raising this lever, this effect
becomes deeper.
@
VCA
Generally called electronic tremolo, the sound signal amplitude is changed according to the modulation signal. The
effect grows deeper when the lever is raised.
@
SUSTAIN i & II SELECTOR SWITCH
When set to SUSTAIN I and several notes are released, each note decays independently. When set to SUSTAIN II,
the decaying note is replaced by another note, when the key for the latter is depressed.
(j)
SUSTAIN LEVER
Controls the decay time from releasing a key to die-away.
@
PORTAMENTO & GLISSANDO SELECTOR SWITCH
The shift from the previously depressed note to the newly depressed note proceeds smoothly in PORTAMENTO,
and in steps in GLISSANDO. If SUSTAIN II is depressed at the same time and the key is released during the shift,
the interval continues to change while decaying.
@
PORTAMENTO & GLISSANDO LEVER
Controls the speed at which the interval changes in the portamento or the glissando.

OUTPUT
Since the synthesizer includes neither power amplifier nor loudspeaker, the sound becomes audible only when the
signal is fed from this terminal to an external amplifier and a speaker. The output level is OdBm for HIGH, and
-18dBm for LOW, when all the volume controls are turned fully clockwise and keys for four notes are depressed.
@
FOOT CONTROLLER·
Connects the expression pedal for free volume control.
@
EXT. IN
Input terminal of external signal for one of modulation signal for sub-oscillator effect. The signal level can be
controlled by the level control.
[V] OTHERS
A headphone can be connected for monitoring to the HEADPHONE terminal, located on the bottom of the CS-50.
