microKORG2 Editing - How the microKORG2 is structured

TIMBRE 1/2
Each timbre consists of the OSC, FILTER, AMP, EG, LFO and virtual patch blocks, among others. As the
microKORG2 has two timbres, you can combine them to create more complex programs.
|
Effects (EFFECT) and equalizer (EQ)
The output of timbres 1/2 is routed to the effects as follows: modulation effect (MOD) → delay effect
(DELAY) → reverb effect (REVERB) → equalizer (EQ).
For the modulation effect, you can choose from nine effects including chorus, six types of delay and
six types of reverb. The EQ is a two-band equalizer.

ARPEGGIATOR
You can apply the arpeggiator’s performance to a timbre. If the program uses two timbres, you can
apply the arpeggiator performance to either or both timbres.
This is a step arpeggiator with ten kinds of arpeggios.

Vocal processors (VOCAL PROCESSOR)
A vocoder, hard tune and harmonizer are available as vocal processors.
Vocoder
A vocoder analyzes the character (the frequency characteristics of each band) of a “modulator” sig-
nal (typically a human voice from a mic), and applies a filter that uses the analyzed characteristics to
the “carrier” signal (a waveform produced by an oscillator or other source), giving a vocal character
to the sound (making it seem as though the instrument is talking, for example).
The microKORG2 has a built-in 16-channel vocoder. In addition to simulating the classic vocoder
sounds of the past, you can use this vocoder to modify the character of the sound, or edit the level of
each frequency band to create truly original vocoder sounds.
Carrier: The carrier signal that’s processed by the vocoder effect is the input sound from timbres 1
and 2 of the microKORG2. Suitable choices for the carrier waveform are sawtooth waves and so forth,
which contain a rich array of overtones. The volume of each signal source is adjusted using the
MIXER, and the signal is output to the vocoder section.
Modulator: The modulator is the signal that’s input to the MIC IN CONDENSER or DYNAMIC jack.
Vocoder section: These are the parameters related to the 16 bandpass filters on the carrier side and
the envelope follower on the modulator side, and are frequently used when shaping the character of
the vocoder.
The audio signal from the MIC IN jack (modulator) is input to 16 bandpass filters, and the Env Follower
detects the volume envelope (time-based change) of each frequency band.
The signal from the internal tone generator (carrier) is then input to the other set of 16 bandpass fil-
ters, and processed by the envelopes detected by the ENVELOPE FOLLOWER to modulate the input
audio, giving the impression that the instrument or sound is talking.
It is also possible to use the Formant to alter the frequency of each carrier bandpass filter. This
causes the frequency characteristic curve to be raised or lowered while preserving the character of
the modulator, which dramatically affects the tone.
