CONTROL 1 [0...127]:
This adjusts the volume balance
between AUDIO IN 1 and AUDIO
IN 2. With a setting of 127 only AU-
DIO IN 1 will be output. With a set-
ting of 0, only AUDIO IN 2 will be
output.
Audio In ( ):
The waveform of the audio signal
input from the AUDIO IN 1 or 2
jacks will be used instead of an os-
cillator.
This lets you apply filtering to a
drum phrase, or synthesize a vocal
or guitar sound together with oscil-
lator 2.
The parameters of the PITCH
section have no effect on the
waveform that is input from the
AUDIO IN 1 or 2 jacks.
CONTROL 2 [0...127]:
LFO1 is used to apply modulation
to the volume balance between
AUDIO IN 1 and AUDIO IN 2 that
you set by "CONTROL 1." The
"CONTROL 2" setting sets the
depth of this modulation produced
by LFO1.
This lets you create effects in which
the AUDIO IN 1 and 2 inputs are
alternated.
Processing an external input audio signal
You can use the filter, amp, EG, and LFO etc. to process the signal from a external
synthesizer, rhythm machine, or audio device in the same way as an oscillator waveform.
Before you connect an external device, turn off the power of the microKORG and of
any external output devices and power amps.
1
Turn the rear panel AUDIO IN 2 VOLUME 2 knob to the MIN position.
2
Connect the output jack of your external device to the AUDIO IN 2 LINE jack.
3
After making connections, turn the power on in the order of your external device, the
microKORG, and finally your powered monitor speaker system.
4
Select a program to initialize, and initialize it.
For this example, select any synth program, and initialize the program as described
on page 59.
5
Turn the EDIT SELECT 1 knob to the OSC 1 position, and turn knob 1 ("WAVE") to
select " " (Audio In).
6
Input an audio signal from your external device, and turn the VOLUME 2 knob
toward MAX as far as possible without allowing the AUDIO IN 2 LED to light red.
7
While inputting an audio signal, play the keyboard.
8
As described in "Basic editing procedure" (➝p.12), edit the FILTER, AMP, EG, LFO,
and effects to modify the sound.
The PITCH-related parameters have no effect on the sound from the AUDIO IN jacks.
In this example, you could connect the microKORG's MIDI OUT to the MIDI IN of
your external MIDI device and set the MIDI channels to match, so that your sound
module or other external MIDI device will produce sound when you play the
keyboard of the microKORG (➝p.49). You can use the microKORG's keyboard to play
the sounds of your external device, and use the EDIT SELECT 1/2 knobs and the edit
control knobs 1–5 to modify the sound.
You can use an external input as the carrier of the vocoder. (➝p.34)
