Troubleshooting

Before you suspect a malfunction, please check the following points.

Power does not turn on

❏Is the AC adaptor connected to an AC outlet? ➝ p.6

❏Is the POWER switch turned on (pressed inward)? ➝ p.6

❏If you are using batteries, are batteries installed? Have the batteries run down? ➝ p.6

No sound

❏If your powered monitor system or headphones connected to the correct jack(s)? ➝ p.5

❏Is the connected monitor system powered-on, and is the volume raised?

❏Is the VOLUME knob set to a position where sound will be output? →p.6

❏Is the MIDI "LOCAL" setting turned ON? →p.51

❏Were any volume-related parameters set to a value of 0? →p.23, 27, 34, 37

❏Was the FILTER "CUTOFF" set to 0? →p.24

❏Did you turn the FORMANT HOLD key on ("E.F. SENSE" HOLD) while there was no input to AUDIO IN 1? ➝ p.10, 35

Can’t input sound

❏Is the input source connected to the AUDIO IN 1 CONDENSOR jack or DYNAMIC jack, or to the AUDIO IN 2 LINE jack? ➝ p.10, 21, 34

❏If you are inputting to AUDIO IN 1 or AUDIO IN 2, is the VOLUME 1 or VOLUME 2 knob turned up? ➝ p.10, 21, 34

❏If you are inputting to AUDIO IN 1, is the MIC/LINE switch set appropriately? ➝ p.4

❏If using a vocoder program, have you connected the modulator audio source to the AUDIO IN 1 CONDENSER jack or DYNAMIC jack? ➝ p.10

❏If you have connected an input device to the AUDIO IN 1 CONDENSER jack and also to the DYNAMIC jack, the input from the CONDENSER jack will take priority, and no signal can be input from the DYNAMIC jack. ➝ p.4

Can't edit

❏If the display does not switch to the parameter indication when you turn the edit control knobs 1–5, Performance Edit may be active. ➝ p.8, 12

❏If you are unable to use the edit control knobs 1–5to edit the parameter value, did you remember to turn the knob to a position that matches the displayed value? ➝ p.13

❏If you are unable to edit timbre 2 of a synth program, has VOICE "SINGLE/ LAYER" been set to LAYER? ➝ p.14, 16

❏If you are unable to edit timbre 1 or 2 of a synth program, is the TIMBRE SELECT 1/2 LED lit for the timbre you want to edit? ➝ p.14

❏If the changes you made to a program or to the global settings have not been remembered, did you turn the power off before executing the Write operation? In the case of a program, your edits will also be lost if you select a different program. Execute the Write operation to save your edits before you switch programs or turn off the power. ➝ p.58

Can't write programs or global settings

❏Is Shift function “MEMORY PROTECT” turned OFF? →p.63

❏If an edited program or edited GLOBAL, MIDI, or SHIFT settings you thought you had saved have not actually been saved, did you set the EDIT SELECT 1 or EDIT SELECT 2 knob to one of the VOICE–ARPEG.Bposition when you attempted to save the program, or to the GLOBAL or MIDI position when you attempted to save the global data? ➝ p.58

Arpeggios do not start

❏Is the arpeggiator turned on (ON/OFF key lit)? →p.11

❏Is the MIDI "CLOCK" setting correct? ➝ p.51

No response to MIDI messages sent from an external device

❏Is the MIDI cable connected correctly? →p.48

❏Does the MIDI channel of the data transmitted from the external MIDI device match the MIDI channel of the microKORG? →p.49

Does not respond correctly to MIDI messages sent from an external device

❏Is the SHIFT function "MIDI FILTER" for that type of MIDI message set to Enable? ➝ p.60

Transpose, velocity curve, and arpeggiator data is not recognized correctly

❏Is Global "POSITION" set appropriately? →p.47

Can't control two timbres on separate MIDI channels

❏The microKORG uses only one MIDI channel to transmit and receive. You cannot use two MIDI channels to play the two timbres independently.
