The Korg Volca Nubass Vacuum Tube Synthesizer features a sound source based around a vacuum tube oscillator and a classic ladder filter, well suited for producers and performers looking for warm harmonics and huge distortion produced by analog vacuum tubes for the ultimate bass machine.

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. The low-pass filter is remarkably 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 electronic music, including the distinctive modulation that can be heard in acid house and techno. The driver circuit uses an analog circuit reminiscent of a classic stompbox, which introduces compression and mild distortion to create a thickness to your bass sound, while the tone knob adds crispiness to the high-frequency range.

The synthesizer can be controlled with its multitouch keyboard or the built-in 16-step sequencer with slide, accent, and transpose functions. The sequencer has 16 memory patches for storing your settings and an Active Step function that can remove or insert steps to help create new bass lines. The unit can receive MIDI from an external controller or DAW via its 5-pin DIN connector. Multiple units from the Volca line can be clock synced with the 1/8" Sync In and Out connectors. The Korg Volca Nubass includes a sync cable and can be powered by the included six AA batteries or with the optional KA-350 AC adapter.

Q: 3. Specifically, I have the 50mm f2 Fuji lens. I need to shoot a bunch of 3X5 index cards. Do I need the MCEX-11 or MCEX-16?

A: FUJIFILM MCEX-11 11mm Extension Tube for Fujifilm X-Mount will be a better combination with your 50mm f/2 lens to make reproductions of a 3x5 index card. Please be aware that you can only focus from the minimum focus distance using an extension tube. If you use FUJIFILM MCEX-16 16mm Extension your lens will only be able to focus on a small segment of your 3x5 index card.

Q: 5. It looks like this doesn't come with a power supply. If that is correct, is there an approved one for this unit?

A: The KeyStep offers two options for powering. The USB port can connect to a computer for both power and data. The USB cable can also be used with a wall plug (the type that you would use to charge a phone), such as the Xuma 2.4A USB Charger with Folding Prongs (B&H # XUCAC124). The other option for powering is to use a standard 9V DC 500mA center positive (5.5 X 2.1 X 12mm) power adapter, such as the BOSS PSA-120S AC Adapter (B&H # BOPSA120S2). Here is a link for the product manual -- see page 15 for info regarding the power options. http://downloads.arturia.net/products/keystep/manual/KeyStep_Manual_1_0_0_EN.pdf
