Volca Keys

Controls

(PLAY) button

Press this button to play the sequence. Playback always starts from the beginning of the sequence. The (PLAY) button will be lit up during playback. Pressing this button again stops playback.

(REC) button The performances in the keyboard buttons are recorded as a sequence. Press this button while stopped to enter record-ready mode (the button will blink), and then press the (PLAY) button to start recording (the button will light up). Playing the keyboard while in record-ready mode will begin recording. Pressing the (REC) button during playback will begin recording from the point where the button was pressed.

VCO (Voltage Controlled Oscillator)

The three built-in oscillators generate the sawtooth or square waves, which become the basis of the sound.

OCTAVE knob: This knob specifies the octave of the notes that will be produced when the keyboard is played.

VOICE knob: This knob sets the VCO operation mode.

  • POLY: Up to three chords of the sawtooth wave can be played.
  • UNISON: The sawtooth wave is produced at the same pitch by the three VCOs.
  • OCTAVE: The sawtooth wave is produced at the fundamental tone by two VCOs and at a pitch one octave higher by one VCO.
  • FIFTH: The sawtooth wave is produced at the fundamental tone by two VCOs and at a pitch a fifth higher by one VCO.
  • UNISON RING: The three VCOs are used to produce sound with ring modulation applied to the square wave.
  • POLY RING: Up to three chords are played with ring modulation applied to the square wave.

DETUNE knob: This knob sets the pitch shift for each of the VCOs 1 to 3. Shifting provides a thicker sound.

PORTAMENTO knob: This knob sets the portamento time. In music, portamento (plural: portamenti, from Italian: portamento, meaning “carriage” or “carrying”) is a pitch sliding from one note to another.

EG INT knob: This knob sets the intensity with which the pitch is changed by the EG.

VCF (Voltage Controlled low-pass Filter)

This filter modifies the timbre (tonal character) by boosting or cutting specific frequency regions of the sound that's produced by the oscillator.

CUTOFF knob: This adjusts the cutoff frequency of the VCF. Turning the knob toward the left will darken the sound, and turning the knob toward the right will brighten the sound.

PEAK knob: This emphasizes the harmonic component of the cutoff frequency. The more that the knob is turned toward the right, the more of an emphas is will be a plied to the harmonic component.

EG INT knob: This knob sets the intensity with which the cutoff frequency is changed by the EG.

LFO (Low Frequency Oscillator)

LFO is the low-frequency oscillator. With its cyclical changes, modulation can be applied to the VCO pitch and the VCF cutoff frequency.

RATE knob: This knob sets the LFO cycle. Turning the knob toward the right will shorten the cycle.

PITCH INT knob: This knob sets the depth (intensit y) of the modulation applied to the VCO pitch.

CUTOFF INT knob: This knob sets the depth (intensit y) of the modulation applied to the VCF cutoff frequency.

EG (Envelope Generator)

The EG functions by changing the VCA level over time. It can be used to apply volume dynamics to a performance.

ATTACK knob: This knob sets the time from note-on (the keyboard button is pressed) until the maximum of the envelope is reached.

DECAY/RELEASE knob: This knob sets the time until the sustain level is reached after the attack level has been reached. This simultaneously sets the time from note-off (the keyboard button is released) until the level becomes 0.

SUSTAIN knob: This knob sets the volume that is maintained while the keyboard button is pressed after the decay time has elapsed.

Settings

Specifying global parameter settings

Setting the MIDI channel

1. While holding down the MEMORY button, turn on the volca keys.

2. Keyboard buttons 1 to 16 correspond to the MIDI channels 1 to 16. Press the button that corresponds to the desired channel, and the LED below the keyboard button will light up.

Other parameters

1. While holding down FUNC button, turn on the volca keys.

2. Press a keyboard button 1-7 to specify the setting for the global parameter. (Refer to the table.)

When you have finished specifying the settings, press the (REC) button. The settings will be saved, and the volca keys will be restarted. If you decide to cancel the settings, press the (PLAY) button.

Parameter LED lit LED unlit
Auto power-off function *Enabled Disabled
Battery type selection Nickel - metal hydride Alkaline
Sync Out polarity Fall *Rise
Sync In polarity Fall *Rise
Tempo range settings Full (10…600) *Narrow (56…240)
MIDI Clock Src *Auto Internal
MIDI RX ShortMessage *On Off

Returning all sequence data to the factory defaults

1. While holding down the FUNC and MEMORY buttons, turn on the volca keys. The (REC) and (PLAY) buttons will blink.

2. Press the (REC) button to return the sequences to the factory defaults and start volca keys. Press the (PLAY) button to cancel the reset operation and simply start volca keys.

Keyboard buttons

Press a button to produce a sound at the specified tone.

MEMORY button The volca keys is equipped with 8 memory locations that are used to save sequences. Press the MEMORY button, and then press a keyboard button between M1 and M8 to load the saved sequence. By pressing the FUNC button and MEMORY button, and then pressing a keyboard button between M1 and M8 will save the current sequence into the memory.

FUNC (function) button The setting for various functions can be specified by holding down the FUNC button and pressing a keyboard button. The LED below the keyboard button will light up or turn off to indicate the setting.

Motion sequencing This function records adjustments made to knobs while a sequence is being recorded. Once the sequence has made a full cycle from the step where a knob was used, this function is automatically deactivated.

Knobs that are adjusted during recording will blink.

FUNC + ON/OFF: This turns motion sequencing on/off.

FUNC + SMOOTH: When motion sequencing is turned on, recorded knob adjustments will change smoothly at the beginning of the step. When motion sequencing is turned off, knobs will change to the settings recorded with each step.

FUNC + CLEAR: All recorded knob adjustments will be erased.

NOTE: Transparent knobs other than the PEAK knob (below VCF) and the TEMPO knob will be recorded with motion sequencing.

LFO settings

FUNC + SAW: This sets the LFO waveform to the sawtooth wave.

FUNC + TRI: This sets the LFO waveform to the triangle wave.

FUNC + SQR: This sets the LFO waveform to the square wave.

FUNC + TRIGGER SYNC: This resets the phase of the LFO waveform when a note is played.

Tempo settings

FUNC + 1/1, 1/2, 1/4: This sets the tempo to 1/2 or 1/4 the information from the TEMPO knob or MIDI IN or SYNC IN jacks. When set to 1/1, the tempo information is used as originally specified.

Metronome FUNC + METRONOME: The metronome will sound while a sequence is being played back. NOTE: The DELAY effect cannot be used while this function is being used.

Step triggering

FUNC + STEP TRIGGER: This force-triggers the EG at the beginning of the step. (Available only when the FLUX function is turned off.)

Tempo delay

FUNC + TEMPO DELAY: This links the delay time to the tempo to easily create rhythmical effects.

FLUX function

FUNC + FLUX: When turned on (button lit), the sequence will be continuously recorded and played back, regardless of the step. When turned off, the performance will be recorded, quantized at the beginning of the step.

Clearing

FUNC + ACT.STP: All steps in active step mode are turned on.

FUNC + ALL: All sequence data will be erased.

FUNC + (REC) during playback: Sound information will be erased while the buttons are pressed.

Active step mode

While holding down the FUNC button, press the button (ACTIVE STEP) to enter active step mode (the button will blink). Each step of the current sequence can be turned on/off. Steps that are turned off are disabled and will be skipped during playback and recording. The button for steps that have been turned on will light up. When you have finished specifying the settings, press the FUNC button to exit active step mode.
