3.OSC1 (Oscillator 1) — SYNTH/VOCODER

WAVE

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 1

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.

CONTROL 2

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.

1Turn the rear panel AUDIO IN 2 VOLUME 2 knob to the MIN position.

2Connect the output jack of your external device to the AUDIO IN 2 LINE jack.

3After making connections, turn the power on in the order of your external device, the microKORG, and finally your powered monitor speaker system.

4Select a program to initialize, and initialize it.

For this example, select any synth program, and initialize the program as described on page 59.

5Turn the EDIT SELECT 1 knob to the OSC 1 position, and turn knob 1 ("WAVE") to

select "" (Audio In).

6Input 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.

7While inputting an audio signal, play the keyboard.

8As 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 1–5to modify the sound.

You can use an external input as the carrier of the vocoder. (➝ p.34)
