Introduction
Thank you for purchasing the Korg volca drum digital percussion synthesizer. The volca drum is a
rhythm sequencer built around a digital synthesis engine focused on percussive sounds. Six drum
parts can be tweaked at will to create original drum kits. From pure tone impulses to gritty
distorted crunches, a wide array of sounds can be created, and further enhanced with a
waveguide-based resonator effect to create other-worldly rhythms.
Sequencer and functions
TEMPO knob
Set the speed of the sequencer.
SWING knob
This knob moves even-numbered steps a maximum of 75%
backward. Hold down the FUNC button while turning this
knob to move the steps in the opposite direction.
Step buttons 1 to 16
By default, step buttons 1 to 6 are used to trigger and select
parts. These buttons also represent the 16 steps of the
internal sequencer, and provide access to various functions.
EDIT/STEP button
Enter step edit mode and enable access to the SLICE and
ACCENT buttons. Press a step button (1—16) to toggle that
step on/off for the selected part. Also, while holding a step
button, the LEVEL [VALUE] knob sets the probability for
that step to be played. Press this button again to exit.
SLICE button:
Enter slice edit mode. Press step buttons
(1—16) to toggle slicing of that step on/off for the selected
part. Also, while holding a step button, the LEVEL [VALUE]
knob sets the number of slices for that step. Press this
button again to exit.
ACCENT button:
Enter accent edit mode. Press step
buttons (1—16) to toggle accents on/off for the selected
part. Also, while holding a step button, the LEVEL [VALUE]
knob sets the amount of accent for that step. Press this
button again to exit.
ACT. STEP button
Enter active step edit mode. Press step buttons (1—16) to set
steps as active/inactive for the selected part. Inactive steps
will be skipped during playback. Press this button again to
exit.
TIP:
Use different active step settings on each part to
create phasing polyrhythms.
STEP JUMP button
Enter step jump mode. Pressing a step button (1—16) will
jump to that step. Press again to exit.
MUTE button
While holding this button, press a step button (1—6) to
mute/unmute the corresponding part.
(PLAY) button
Start/stop sequencer playback. This button will light up
during playback.
(REC) button
Record your performance on step buttons 1—6, and on the
transparent sound control knobs if motion sequencing is enabled.
Pressing this button while playback is stopped will enter
record-ready mode; recording will start when the PLAY button, or a
step button (1—6) is pressed. Pressing this button during playback
will start recording from the point at which you pressed the button.
TIP:
During playback, knobs with recorded motion will light up.
TIP:
When motion sequencing is enabled, record will be automatically
deactivated one cycle after the first knob motion is recorded.
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 drum 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 drum 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 drum is turned on, the LEDs below the step
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 drum.
TIP:
If the batteries are running low during usage of the
volca drum, the low battery warning “bt.Lo” will appear
in the display. If the batteries run down completely, the
volca drum automatically turns off.
Global Parameters
1. While holding down FUNC button, turn on the volca drum.
2. Use the step buttons 1—8 to set your preferences for any or all of the global parameters. (Refer to the table.)
3. When you have finished, press the
(REC) button. Your settings will be saved, and the volca drum will restart. To cancel without
making changes, press the
(PLAY) button.

channels 1 to 16. Press the button that
corresponds to the desired channel, and
the LED below the step button will light up.
TIP
Tapping the step for the selected channel
(LED lit up) cancels the selection and
reverts to part 1–6 assigned to channels
1–6. (factory default)
SYNC (IN, OUT) jacks
These jacks allow you to synchronize your
volca drum to another Korg volca, or other
compatible equipment—including an analog
sequencer or a DAW. The polarity of the SYNC
jacks can be set using the global parameters.
•
SYNC OUT:
A 5 V pulse of 15 ms is sent at
the beginning of each step.
•
SYNC IN:
If this jack is connected, the
internal step-clock will be ignored, and the
volca drum sequencer will advance
according to the pulses received here.
(Headphone) jack
Connecting your headphones to this 3.5mm
stereo mini jack will mute the volca drum’s
internal speaker and allow you to create music
in private.
VOLUME knob
Set the output level of the volca drum.
MOD RATE knob
Set the pitch modulation rate for the selected layer.
EG ATTACK knob
Set the attack time of the amplitude envelope generator
for the selected layer.
EG RELEASE knob
Set the release time of the amplitude envelope generator
for the selected layer.
SELECT [PARAM] knob
Cycle through permutations of sound sources, pitch
modulators, and amplitude envelopes for the selected layer.
Sound sources (SRC): sine wave <
>, sawtooth wave
<
>, high pass filtered noise <
>, low pass filtered
noise <
> and band pass filtered noise <
>.
Pitch modulators (MOD): rise-fall <
>, oscillate <
>,
and random <
>.
Amplitude envelope generators (EG): linear attack-release
<
>, exponential attack-release <
>, multi-peak
