Introduction

Thank you for purchasing the Korg volca fm DIGITAL FM SYNTHESIZER. This digital synthesizer uses a 6-voice, 6-operator FM (Frequency Modulation) sound engine.
In addition to the basic FM sound parameters, there are also a number of volcafm-specific parameters that provide further sound-editing capabilities. Sound files
(SYS-EX/SYX) created on the Yamaha DX7 can be converted and loaded into the volca fm. Sounds created on the volca fm can be exported and shared with another volca fm.
In addition, the volca fm also includes a built-in step sequencer, motion sequencer, and an arpeggiator—plus various voice modes—that can all add movement, depth, and expression to your volca fm sounds.

FM (Frequency Modulation) is based on synthesis elements known as operators.
The volca fm sound engine uses six operators. Operators can function as either modulators or carriers; modulating operators apply modulation to audio-source carrier operators to create sound. The way that these modulating and carrier operators interact is called an algorithm; the volca fm provides 32 distinct FM algorithms.
In the EDIT mode, the parameters required for the FM sound source, such as the LFO waveform and speed as well as the EG level and rate, can be set for each operator.

TRANSPOSE slider
This slider raises or lowers the pitch in units of octaves or semitones.

VELOCITY slider
In PLAY mode, this slider controls the global velocity. In EDIT mode, this slider
functions as the VALUE slider for editing the FM synthesis parameters.

OCTAVE ,/ OPERATOR +, – buttons
In PLAY mode, these buttons change the octave range of the keyboard. In EDIT mode, these buttons select the operator to edit. By selecting “A” (All), you can edit parameters that apply to all operators.

SAVE/EXPORT button
When not in EDIT mode, this button saves the FM sound engine parameters.
Press the SAVE/EXPORT button, and then use the PROGRAM knob to select the save location for the program. Press the SAVE/EXPORT button again to begin saving. To cancel the save operation, press the EDIT button before pressing the SAVE/EXPORT button.
Exporting
You can connect the volca fm’s SYNC OUT jack to the SYNC IN jack of another volca fm unit, and export (transmit) FM sound programs and sequences to the other volca fm unit.
In EDIT mode, press the SAVE/EXPORT button so that the button blinks, and then use the PROGRAM knob to select the item to be exported. After selecting the item to be exported, press the SAVE/EXPORT button again to export it. The SAVE/EXPORT button lights up while the export operation is being performed. The SAVE/EXPORT button blinks again when the operation is finished.

Installing the batteries

On the back panel, locate the battery compartment and slide off the cover. Insert the batteries—being sure to observe the correct polarity—and then replace the battery cover.
Turn the volca fm off before replacing the batteries.
Remove depleted batteries at once. Depleted batteries left in the battery
compartment may leak over time, and may cause malfunctions. Also, remove the batteries if you will not be using the volca fm for an extended period of time.
Do not mix partially used batteries with new ones, and do not mix batteries of differing types.

Battery level indicator
When the volca fm is turned on, the LEDs below the keyboard buttons indicate the remaining amount of battery power. If all LEDs are lit up, the batteries are completely full. Fewer lit LEDs mean that the battery level is correspondingly lower.

When using the AC adapter, the remaining battery level will not be indicated correctly.
TIP Either alkaline or nickel-metal hydride batteries can be used. In order for the remaining battery level to be detected and indicated correctly, the type of batteries being used must be specified in the global parameters of the volca fm.

TIP If the batteries are running low during usage of the volca fm, the low battery warning “bAtt Lo” will appear in the display. If the batteries run down completely, the volca fm automatically turns off.

TIP It’s not possible to turn off the low battery warning; however, you will be able to continue using the volca fm until the batteries have run down completely.

About the MIDI implementation chart
The volca fm can be controlled via MIDI; simply connect the MIDI output of an external MIDI device to the MIDI IN jack of the volca fm. The MIDI messages that can be received by the volca fm are listed in its MIDI implementation chart. You can download the MIDI implementation chart for the volca fm from the Korg Web site.
