A powerful bass synth with a sound source based around a vacuum tube oscillator
The acid bass machine with the pinnacle of modulation and distortion

Even today, when digital technology allows electronic musical instruments to simulate any sound imaginable, people seek the warm harmonics and distortion produced by analog vacuum tubes. This distinctive sound has a quality beyond words that sets it apart, and cannot be captured by a response curve; it's the unmistakable sound of tubes.

Key Features:
• A powerful sound source based around a vacuum tube oscillator.
• Equipped with a Nutube new-generation vacuum tube in the oscillator
• A transistor ladder low-pass filter that produces a distinctive sound
• Analog driver circuit that uses an analog circuit reminiscent of a classic stompbox.
• 16-step sequencer that lets you automate parameters
• Motion sequence function can record knob movements
• Three sequencer functions add transpose, accent, and slide that are distinctive for acid bass
• Connections to sync with KORG groove machines and other gear

The volca nubass is the first analog synth to be equipped with a Nutube new-generation vacuum tube in its
oscillator. Vacuum tube plus analog means that the sound is warm, thick, and rich. The familiar transistor ladder
filter gives it the character of a classic bass machine, along with overdrive, and huge-sounding distortion.

An acid bass machine for a new generation combines classic sound with the power of modern synthesizer design. It's
the volca nubass.

The fusion of a newly developed vacuum tube oscillator with a classic ladder filter
A vacuum tube oscillator circuit forms the heart of volca nubass, utilizing groundbreaking Nutube technology
"The Nutube contains two independent triodes; one is used in the oscillator to generate a sawtooth wave or square
wave. The other triode is used in the drive circuit of the sub oscillator, adding depth and warmth one octave below
the oscillator. This oscillator and sub oscillator provide a circuit structure that brings out the harmonic character that
only a real vacuum tube could provide.

A transistor ladder low-pass filter that produces a distinctive sound
The low-pass filter defines the sound of this bass machine; it uses a transistor ladder design found on classic analog
bass synths. This filter is uniquely dynamic in the way it affects a sound more than just ranging from bright-to-dark.
Its wide range of timbral possibilities makes it ideal for a broad variety of dance music; you can use it to create the
distinctive modulation that can be heard in acid house, or increase the resonance to bring out a sharp character
that's appropriate for techno.

Analog driver circuit
nubass is equipped with overdrive that uses an analog circuit reminiscent of a classic stompbox. Turning the knob
toward the right compresses the volume while causing mild distortion, adding thickness to your bass sounds. The
tone knob also lets you adjust the crispness of the high-frequency range.

Volca sequencer makes performing and composing simple and intuitive
A 16-step sequencer that lets you automate parameters
The volca nubass is equipped with a full-fledged 16-step sequencer with a variety of functionality; by using it in
conjunction with a rhythm machine, you can construct rhythm tracks or loop music.

You can use the 16 buttons for step input just like the rest of the volca series, or play the buttons as a keyboard for
realtime recording. The chain function lets you play back multiple sequence patterns in succession, allowing you to
loop up to 16 sequences.

The motion sequence function can record knob movements, applying parameter changes over time to the sound.
This can be used when creating loops, or for live performances that are dynamic and original. Up to 16 sequence
patterns together with motion sequences can be saved in internal memory.

There's also an active step function that lets you skip steps that you specify during playback; sequence patterns
become more dynamic and exciting when they can be edited in real time during performances.

Three functions to create grooves on volca nubass

The sequencer of the volca nubass provides three functions that add the slap and slide performance techniques that
are distinctive of acid bass: these transpose, accent, and slide functions are accessible and controllable through the
step sequencer.

Transpose is a function that plays a note one or two octaves higher; it adds movement to the bass line while staying
within the original scale. Accent emphasizes a note, creating dynamics that make the rhythm expressive. And the
slide function that's indispensable to acid sound creates a smooth transition to the next note. Use these functions to
add a sense of groove, and volca nubass will come alive in your performances and compositions.

Randomize settings can be applied to each of these three functions. In addition to generating unpredictable
patterns, you can update the randomize settings to keep varying the patterns, bringing out more unexpected and
exciting ideas from the sequencer.

Excellent playability
Connections to sync with KORG groove machines and other gear
Using volca nubass’ sync in and out, you can connect it to another volca series unit or to equipment such as an
electribe, any Korg “logue” synth, or the SQ-1, and enjoy synchronized playback with the sequencer. There's also a
standard MIDI IN connector, so you can use the volca drum as a sound module for your DAW.

Enjoy anywhere
Compact, size, battery operation, and built-in speaker mean that you can take this unit anywhere and enjoy playing
on the go.

Free bundle of music software
The volca nubass comes with a diverse variety of music software from Izotope including “Ozone Elements” which lets
you not only create songs but also master them using AI, “Skoove” which will help you improve your keyboard
playing skills, “Reason Lite” DAW software, as well as software synths from KORG and other brands.

In other words, the moment you get your hands on this synthesizer you'll have a variety of tools to help you take
your music to the next level.
