INSIDE THE BOX—Korg SV-1 BK Black Stage Vintage Piano—73-key

36 acoustic and electric keyboard sounds

The 36 base sounds in the SV-1 BK span a range of acoustic and electric pianos, organs, strings, and synth. Each instrument category begins with the essential classics and then moves beyond into some rare and unique instruments. The acoustic pianos include three-way stereo versions of the ubiquitous Japanese and German grand pianos; a more intimate upright piano, a much-needed mono piano for small gigs; a late ‘70s-mid 80’s Japanese electro-acoustic variation, plus some blended sounds. The electric pianos include a seven-way velocity switched “tine” version, classic “reed” based model, vintage analog “electra” instrument (all from American manufacturers), as well as two different Japanese mid-80’s digital classics.

Organs include three variations of the classic tone-wheel model, plus the most famous British and Italian combo organs, along with the first known offering of a signature American tube- driven console organ.
Clavinets include four variations plus a related keyboard that used a plucked-reed mechanism for a unique and intimate sound. Also featured in the SV-1BK are real, tape-based, and analog strings; choir; and a couple of fat analog synth sounds.
Each of the core instruments has been accurately sampled including tine, key-off, damper, and hammer noises at different velocities. Korg even sampled piano cabinet resonances to enhance the accuracy of the pianos. This attention to detail, called the RX Experience, is what makes playing the SV-1 BK a joy.

Vintage FX chain and amp modeling

To complement the meticulously crafted sounds of the SV-1, there are six separate stages of signal processing, all bypass-able.

Equalizer (bass, middle and treble)—EQ, adjustable from the front panel, allows you to shape the tonal quality of your sound in real-time.

Pre FX (Compression, Boost, U-Vibe, Chorus/Vibrato, Tremolo, Wah)—this section provides essential effects plus some vintage vibe, with classic effects modeled by Korg’s legendary guitar effects designers. Add a Korg EXP-2 or VXP-10 expression pedal to control the Wah effect on the clavinets, for example.

Amp Model (Amp Modeling, cabinet simulation and noise reduction)—A range of amp heads and speaker cabinets are available to add color, drive and edge to your sound. Selecting an amp head calls up an appropriate cabinet. However, you have the ability to independently select cabinets for a wider range of tonal options. In addition, Korg’s exclusive Valve Reactor circuitry adds the warmth or snarl that only a real tube can provide.

Modulation FX (Chorus 1 &2, Phaser 1&2, Flanger and Rotary)—Some of the most famous stomp-box pedals have been recreated to give you the signature sounds for these legendary timbres. Korg’s rotary speaker emulation has long been acclaimed as one of the best, faithfully adding nuance and motion to any organ sound.

Reverb/Delay (Room, Plate, Hall, Spring, Tape Echo and Stereo Delay)—Four types of reverb are provided, along with a classic tape-echo, plus a tempo-based digital delay. The SV-1 also includes a tap tempo switch.

Limiter—This final step in the chain ensures your level remains balanced across all sounds, and is adjustable only via the included computer editor/librarian software.

Intuitive and simple interface

The SV-1 BK was designed with performance in mind. All essential controls are accessible on the front panel; no multiple button presses to scroll through hard to confusing menus and hard to read displays. Rotary knobs include illuminated LED’s to show the position of the knob, and can be pressed to restore the original setting. For really quick changes, the SV-1 BK has eight car-radio style buttons to instantly call up your most used sounds and settings. Storing a “Favorite” is easy. Simply adjust the controls to your preferred settings, then press and hold one of the Favorites buttons; when the button flashes, press it again and the settings are now stored.

Korg’s finest keyboard, tuning curves

We’ve come a long way since the beginning of electronic keyboards. Manufacturers were happy just to get a keybed that actually worked consistently (just ask anyone who dropped $40k on an original Synclavier before the double-triggering keyboard was repackaged at a mere $9k). Fast-forward to today, the SV-1 BK is equipped with Korg’s finest graded-hammer action (RH3) keyboard on both the 73-key and 88-key versions.

The SV-1 has a Function button that provides access to eight different keyboard tuning curves, including equal, grand piano stretch, electric piano stretch, electric grand, upright stretch, detuned, and two user-definable types (configurable using the editor/librarian software). Overall tuning can also be accessed via the Function button, and adjusted by using the EQ treble control. While in this mode, concert pitch (A=440) can be recalled quickly by pressing the treble encoder pot. The SV-1 BK can be transposed into any key.

Editor/Librarian Software

While setting out to create an incredibly friendly and easy-to-use instrument, we knew that there were more tech- savvy players out there that would love nothing more than to dig in a little deeper. The SV-1 Editor/Librarian software provides cool graphic-based programming, including access to certain parameters not available on the SV-1’s panel. In addition, the Editor/Librarian software allows each of the 36 sounds and the eight Favorites to be programmed and saved individually. This points the way to users sharing and swapping their favorite settings, and for Korg to supply more sounds in the future. The SV-1 Editor/Librarian runs on Mac or PC, and is included free with every SV-1.

OUTSIDE THE BOX—Korg SV-1 BK Black Stage Vintage Piano—73-key

Retro styling—Housed in a bold, curvaceous body, the elegant black matte finish of the 73-key SV-1 BK stands out from the crowd. Its retro-style controls include a front-panel 12AX7 tube for adding output saturation; a master volume section; 3-band equalizer section; Pre FX section; Amp model section that lets you select six classic amp models; a Favorites preset section with eight radio-style buttons; a Sound section, with Type and Variation knobs; transpose button; a Local Off button that lets you use the SV-1 as a master MIDI controller; Touch button to adjust keyboard sensitivity; Function button; Modulation FX section; Reverb/Delay section; and power switch. For private practice, the SV-1 also has a stereo 1/4″ headphone jack.

Connectivity—The SV-1 BK is equipped with balanced XLR and 1/4″ outputs; Left and Right audio inputs; MIDI In and MIDI out jacks, USB MIDI Port, and 3 pedal connections: Damper, Pedal 1, and Pedal 2. The Damper pedal is included, and responds to half-pedaling for authentic piano response. Pedal 1 is designed for a switch type of pedal, and can operate as a piano Sostenuto pedal, or as a Fast/Slow switch when the Rotary Speaker effect is on. Pedal 2 can accept either an expression pedal—great for authentic Wah effects—or an additional switch pedal, providing the piano purist with access to all three piano pedal functions by adding the Una Corda (soft) function.

For convenient transport, the optional CB-SV1 73 rolling carry bag fits both the SV-1 73 and ST-SV1 stand.

The amazing sounding Korg SV-1BK provides an economical, reliable, portable, and maintenance-free alternative to collecting and maintaining a stable of vintage instruments. For more information, call or chat with your Westlake Pro sales consultant today.
