Synthesizer Vocoder Introducing the microKORG

State-of-the-art analog modeling and multi-band vocoding are available in this compact, portable synthesizer vocoder. With 37 keys and 128 user-rewritable programs, the microKORG Synthesizer/Vocoder is perfect for the performer, producer, computer musician or beginner looking for an affordable synthesizer. The Korg microKORG delivers the quality sounds and features you expect from Korg at a price that will astound you.

Powerful synthesis
The microKORG boasts the same dual-oscillator DSP synthesis engine found in Korg's critically acclaimed MS2000 and offers a wider selection of waveforms than any other modeled synth. Oscillator 1 features a total of 71 waveforms including traditional analog waves like saw, pulse, sine and noise, plus more unique choices like Vox wave and cross wave. Together they provide a cool selection that can be modulated to produce an extensive range of timbres. In addition, 64 exclusive DWGS waveforms from Korg's classic DW-8000 enable the microKORG to reproduce a broad collection of imitative sounds. Sounds like bells, electric pianos, guitars, basses and more that would be difficult reproduce on an analog synthesizer can easily be produced with a synthesizer vocoder such as the microKorg. You can also apply Ring and Sync modulation from Oscillator 2 to create the kind of complex timbres that are the true sign of an advanced synthesizer.

Four filter modes are available, offering -12 dB (2-pole) low pass, high pass and band pass configurations plus an extra steep -24 dB (4-pole) low pass setting. All modes and settings include resonance. Two classic ADSR envelope generators and two MIDI-syncable LFOs provide the power to shape your sounds. Add a Virtual Patch matrix that lets you create advanced modulation settings - routing the Mod Wheel to control filter cutoff or pulse width, using an LFO to control panning or amp level, etc. - and you have performance that is unheard of from a synthesizer vocoder in this price range!

Classic vocoding
The microKORG includes an 8-band synthesizer vocoder with many advanced features. You can capture and "freeze" the formants of your voice, and then play it across the keyboard, or shift the formant frequency to make your voice sound male, female, like a child or just plain wacky! Best of all, the microKORG comes with its own microphone so you can start having fun right away.

A full range of effects Three types of modulation effects (chorus/flanger, phaser, ensemble), three types of delay effects (stereo, cross, L/R), and a two-band equalizer add the finishing touches to the microKORG. The delays can be synchronized with the arpeggiator or to an external MIDI clock - a great feature for live performances or for laying down tracks. All effects can be edited to create your own, unique sounds.

Great sounds and expression
Korg has used all of the microKorg's synthesis power in the creation of 128 great-sounding presets. They cover a wide range of the latest musical styles plus many vintage favorites. Sixteen vocoder Programs are also included. The Pitch Bend wheel, Modulation wheel and five other knobs provide flexible realtime control over filter cutoff, attack, release and other important parameters. The Edit Mode allows you to fully edit the existing sounds or create your own new ones.

Flexible arpeggiator
Six types of arpeggio patterns (UP, DOWN, ALT1/2, Random, Trigger) are built in, with control over tempo, gate time, swing, and up to a 4-octave range. You can turn individual steps on or off within a pattern, providing the feel and functionality of a step sequencer.

Audio in - Creativity out
Two external audio input jacks are provided, so you can run other instruments, CDs and more through the microKORG's filter and effects, allowing you to process sounds in truly creative ways.

A compact MIDI controller
The compact size of the microKORG synthesizer vocoder is perfect for the musician or DJ looking to add a synth to his or her setup when space is tight and it is a great choice for use in a computer-based music setup. The five realtime knobs on the front panel can transmit MIDI messages (control changes), so they can be used as controllers for software synthesizers. Use the 37-note velocity-sensitive mini-keyboard for controlling other gear or for recording and editing with your sequencer. And thanks to battery-power, the microKORG synthesizer vocoder is the ultimate portable controller when used with a laptop computer!

Clear control and classic looks
There's no complex menu structure - all parameters are located on the panel for easy access to any function. A large dial and LED illuminated buttons provide easy program selection even on a dark stage. With its beige-gold body, wooden side panels and retro-influenced design, the microKORG has a look that's both vintage and funky.

Meet The New Micro!
For years, the microKORG has been the world's top-selling music synthesizer. Now, the microKORG XL is ready to join the Korg line-up. Based on the same winning combination of a small footprint, mini-keys, battery-powered portability and huge Korg sound, the microKORG XL is ready to expand your musical vocabulary. The fun factor is huge, too. A gooseneck microphone is included for instant synthesizer vocoder excitement, right out of the box!

Neo-Vintage Music Synth Power
The microKORG XL music synthesizer carries a proud pedigree. The MMT (Multi Modeling Technology) sound engine is descended from the RADIAS/R3 synthesizers, while the dual effects processors come down from the famous KAOSS line. The microKORG XL also offers remarkable playability. For example, the black key/white key proportions have been adjusted for easier chording and the key response has been improved for rapid-fire soloing. And the old -school square front keys? Well, they look wicked cool! Together with a sound-bending vocoder and six-pattern arpeggiation, microKORG XL packs a powerful sonic punch.

The eight-voice MMT synth engine in the microKORG XL music synthesizer offers traditional analog waveforms plus a total of seven algorithms, including formant waveforms, noise, and PCM/DWGS waves for those vintage keyboards and strings. Cross-modulation, unison stacking, and VPM (Variable Phase Modulation) let you create sounds that would be impossible for a conventional PCM synthesizer to generate. Sync and ring modulation also make it easy to create complex and powerful sounds. Two multi-mode filters, a drive/waveshaping circuit for distinctively distorted sounds, and EG and LFO for creating time-varying tonal change, all provide plenty of parameters for serious synthesis. Virtual Patching brings it all together.

Seventeen up-to-the-minute effects deliver everything from a traditional chorus all the way to grain shifting. In addition, delay effects can be synchronized to a MIDI clock for "beat-sensitive" situations. You can even process external sounds! The microKORG XL's amazing vocoder adds vocal characteristics to any sound, creating everything from pseudo choirs and talking instruments to vintage Sci-Fi robots. Our unique Formant Hold allows you to freeze the vocal input for continuous vocoder effects. You can also use the Formant Shift function to adjust the level and pan of each of the sixteen bands, greatly altering the tonal character. The distinctive retro-styling of the microKorg XL music synthesizer allows for quick selection of any of the 128 on-board, editable programs. For the diehard synthesists and sound designers, the three performance edit knobs provide for fast and effective editing.. You're also free to select and assign your favorite parameters!

Superb piano sound in a digital stage piano

The robust sound of a concert grand piano has been carefully and lavishly sampled for this digital stage piano. Differences in playing dynamics and position in the stereo field have been faithfully captured, delivering naturally expressive piano sounds that recreate every detail. The SP-250's all-new piano samples are longer than other pianos in its class. Increased length means the piano sound sustains more naturally, so the piano sounds more real throughout the performance, not just at the attack. Three versions of sound are provided in this wonderful and portable digital stage piano to cover different tastes and genre needs. To round out the piano offerings, the SP-250 also features a vintage electric grand sound, as well as an authentic honky-tonk piano.

Grand piano playing experience
The SP-250 is the first portable digital stage piano from Korg to feature the all new RH3 real weighted hammer action. This state-of-the-art key mechanism features differing key weights in each register of the keyboard, delivering the same playing experience as a grand piano. The keyboard is exceptionally responsive, even when playing quickly repeated figures, to preserve every expressive nuance of the performer. The Key Touch Control provides three selectable touch curves, delivering the perfect touch sensitivity for every playing style or type of song. Yet, even with such a robust keyboard, the SP-250 weighs less than 42 pounds (19 kg.).

A wide palette of sounds
In addition to its remarkable new piano sound, the SP-250 portable digital stage piano includes a rich array of sounds that will extend your performance possibilities. An assortment of classic electric pianos (reed and tine styles), church and jazz organs, string and choir sounds, harpsichord and clav(s) elements and even mallet percussion and guitar sounds, are all available at the touch of a button. Two sounds can be layered together to play simultaneously; and of course, you can adjust the balance to get the perfect blend. To help you audition the sounds, 30 demonstration songs ranging from classics to originals are built in to this digital stage piano, showing off all the sounds in a variety of musical genres.

Dual effects
To further enhance the sound, the SP-250 provides both a Reverb effect, that recreates the spaciousness of a concert hall, and a Chorus effect that adds a colorful depth to the sound. The effects settings have been optimized for each individual sound and the user can choose from three levels - Light, Normal and Deep - to complement his or her performance.

Style and versatility
The chic black design is highlighted by metal and wood-grain accents, with a solid music rack included that mounts in seconds. The control panel is simple and easy-to-use and includes 19 LED indicators providing for instant visual feedback. The SP-250 is perfect for those who appreciate quality in both sound and design.

Full range sound system
The SP-250 contains a custom system, featuring two 10 cm dual-cone speakers matched to a pair of 11-Watt amplifiers that beautifully reproduce the rich sounds of a piano. The bass-reflex speaker system ensures that every bit of the deep resonances distinctive to a great piano will be heard.

Stand and pedal included
The SP-250 portable digital stage piano includes a high-quality damper pedal that is vital for proper piano performance. It provides the ultimate expressive control thanks to half-pedaling, which is a variable damping effect based on how deep you press the pedal, rather than the simple on/off switch found on cheaper instruments. The dedicated stand is both simple and stylish, and fits securely into a recessed area in the bottom of the piano, providing a remarkably solid feel. The stand's lower crossbar even prevents the pedal from "creeping" forward in performance. Best of all, the SP-250 can be easily removed from the stand for easy moving and carrying during live performances.

Convenient features
Two headphones can be connected simultaneously, providing for student-teacher use or family enjoyment. Thanks to stereo outputs, you can listen to the sounds of the SP-250 through external speakers, a great feature for professional performances, schools and places of worship, and for recording purposes. MIDI In/Out jacks connect the SP-250 portable digital stage piano to a synthesizer or other MIDI-equipped device (computer/sequencer), allowing the SP-250 to be used as both a master keyboard and a 16-part multitimbral sound module for performance and composition.

The Key Transpose function lets you shift the pitch of the instrument to match the key of a singer, or to play along with your favorite CDs. An onboard Metronome is convenient for practicing. You can add an accent to the first beat (with normal or bell sounds), and adjust its volume. There's also a dedicated slider for easy adjustment of the tempo.

In addition to equal temperament, the SP-250 provides the two most common Baroque and Classical era tunings (Kirnberger and Werckmeister) for historically-accurate performances.
