3) Random ( RND )
The signal produces random changes in delay time, at a rate determined by the FREOUENCY control. It is very useful
for realistic doubling effects and various special effects.
Envelope ( ENV )
4)
The Envelope Follower causes Delay time to vary according to the amplitude envelope (volume change over time) of
the audio input signal. As the volume of the sound increases, Delay time will become shorter. This is useful for
Doppler effects and for touch responsive chorus and flanging effects.
b) INTENSITY Control
The INTENSITY control determines the degree (depth) to which D elay time will be affected by the selected
Modulation WAVEFORM or external DELAY MOD input signal. At 0, the Delay time will remain constant at the
value shown in the LED display. As the control is turned clockwise, the Delay time will begin to change; how it
changes depends upon which Modulation source is selected. Modulation always causes the delay time to become
shorter than the value shown in the LED Display, by a varying amount. At a control setting of 10, Delay time will vary
over a range of 2:1, or from 100% to 50% of the displayed value. Thus, if the display shows a 'value of 1000
milliseconds, the actual Delay time will vary between 500 and 1000 milliseconds in a manner that depends upon the
shape and frequency of the Modulation source.
c) FREQUENCY Control
The FREQUENCY control determines the rate or frequency of the TRIANGLE, SQUARE and RND waveforms.
FREQUENCY may be varied over a range of 0.1 Hz, (1 cycle ever" 10 seconds) to 15 Hz. (15 cycles per second).
A flashing LED indicates the current FREQUENCY setting.
d) DELAY MOD Control Input Jack (Rear Panel - ? )
The DELAY MOD input allows an external Control Voltage to vary the Delay time setting. This control voltage should
be in the range of O - 5 volts; the higher the voltage, the shorter the Delay time. A KORG MS-01 or MS-04 Pedal or
other voltage source may be connected. The maximum modulation depth is 2:1, depending upon the INTENSITY
setting; with a 5 volt input, Delay time will be 50% of the displayed value (INTENSITY = 10).
All internal modulation is disabled (switched out) when a plug is inserted into the DELAY MOD jack.

5. Effect Section

The Effect Section contains the following:
a) LEVEL BALANCE Control
The LEVEL BALANCE control determines the relative amounts of Direct and Delayed signal in the final audio output
mix.
At 0, only the Direct signal will be present. At 10, only the Delayed signal will be present. Settings in between O and 10
will produce a continuously variable blend of the two different signals.
