A vacuum tube oscillator circuit forms the heart of volca nubass, utilizing groundbreaking Nutube technology

The Nutube is equipped with two vacuum tubes; one is used in the oscillator to generate a sawtooth wave or square wave. The other vacuum tube 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.

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.

Excellent playability

Connectors that allow synchronized performance and external control

Since this unit provides a sync jack for easy connection to Korg groove machines, you can connect it to another volca series unit or to equipment such as an electribe 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 nubass 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.
