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.
