VCO (Voltage Controlled Oscillator)
The oscillator generates the waveform that’s the basis of the sound: a
sawtooth wave, triangle wave, or square wave. The noise generator
produces white noise. If an external audio source is connected to the
AUDIO IN jack, it will be mixed with the VCO’s output. The VCO
generates a waveform at a pitch that’s determined by the position
being touched on the ribbon keyboard or by performance data that
you’ve recorded as a sequence. In addition, the LFO can also apply
time-varying changes to the pitch.
1. OCTAVE selector
This specifies the VCO pitch in steps of an octave. With the ”64’” set-
ting, the pitch range of the ribbon keyboard will be A0–D2.
2. WAVE select switch
This selects the VCO waveform: sawtooth, triangle, or square.
(Sawtooth wave)
(Triangle wave)
(Square wave)
3. NOISE knob
This knob adjusts the level of white noise that’s mixed with the VCO
output.
4. RANGE select switch
This specifies the ribbon keyboard’s playing mode.
WIDE The pitch range will be extended to approximately
six times that of the NARROW setting; pitch change
will be continuous. The OCTAVE selector will be
ignored.
NARROW The pitch will change continuously according to the
printed ribbon keyboard.
KEY
The pitch will change in chromatic steps according
to the printed ribbon keyboard.
VCF (Voltage Controlled Filter)
The filter modifies the timbre (tonal character) by boosting or cutting
specific frequency regions of the sound produced by the oscillator.
The monotribe uses the traditional 12 dB/oct low-pass filter (LPF)
that was also used on the Korg MS-20. The character of the sound will
change significantly depending on the settings of this filter. In addi-
tion, you can use the LFO to modulate the filter ’s cutoff frequency
over time.
5. CUTOFF knob
This adjusts the cutoff frequency of the VCF, affecting the brightness
of the sound.
Turning the knob toward the left will darken the sound, and turning
the knob toward the right will brighten the sound.
6. PEAK knob
This adjusts the resonance of the VCF, adding emphasis to the cutoff
frequency.
VCA (Voltage Controlled Amplifier)
The amp varies the volume of the sound. You can use the EG to make
the volume change over time.
7. LEVEL knob
This adjusts the volume.
