MODULATOR
Functions for Playing
Keyboard
The MODULATOR, which consists of the
LFO (Low Frequency Oscillator) and S/H
{Sample & Hold}, sends the signal control-
ling the VCO and VCF. Also, Noise can be
selected to modulate the VCO and VCF.

The LFO also provides the output wave-
form of ~ which controls the VCO and
VCF: by using the BENDER in the Con-
troller Section.
The SH-101 has 32 keys and 2% octaves,
but can be played as a 56 key keyboard
{as shown below) by using the TRANS-
POSE switch.

@ WAVEFORM selector switch
This is to select the output signal of the
MODULATOR. Avand FU are the out-
put waveforms from the LFO. These
modulate the VCO and VCF producing
vibrato and trill {VCO}, or growl (VCF}.
If choosing the RANDOM (output signal
of S/H), the control voltage arbitrarily
changing will be generated and applied to
the VCO or VCF to produce the Random
Note or the Random Filter. When the
Noise position is selected, the noise will
work as a control signal and a fast changing
modulation will be obtained. (Noise Modu-
lation}
@) LFO/CLK RATE
This knob determines the rate (frequency)
of the LFO and S/H.
* EXTCLOCK > Refer toP.38.
When the Range of the VCO is set to 8'
and the TRANSPOSE switch to NORMAL,
the lowest Do (C} corresponds to the
Middle C of a piano keyboard.
