XK5

“It’s very important to feel comfortable sitting at the organ. Sometimes I play an organ and it doesn’t feel like what I’m used to. First of all, [The XK-5] feels like a B-3, just sitting at it.”

– Dr. Lonnie Smith, legendary jazz organist 

“It’s a Hammond B3! That’s what most of us want in essence. But to be able to go beyond that and have all these incredible adjustments … I’m in love!”

“I’m so glad Hammond is carrying on the tradition, and making it even better than it was in the beginning. Congratulations!”

– Chuck Leavell (Rolling Stones)

Let’s face it: Moving and maintaining an antique Hammond will only become more difficult as time passes. Of course we have tons of respect for anyone who does, but to get all of the sound with none of the hassle, let’s learn why the XK-5 is destined to become The New Original™ 

NEW PATENT-PENDING TECHNOLOGIES

Hybrid Multiple Key-Contact System: On classic Hammonds (and in our current, full-sized New B-3 Mk. II family), pressing a key sequentially closes nine mechanical contacts: one for each drawbar. In normal play, your ears hear these multiple harmonics as one note. Depress a key slowly, however, and you hear the harmonics come in at slightly different times. Normal playing created a subtle “slop” between otherwise crisp attacks, and the more drawbars pulled, the more “chewy” and soulful character it imparted to the sound. Some called it “bounce”, and it was also indelicately referred to as “spit”. Many beloved Hammond keyboard “tricks” were born of this unintended imperfection.

These unique responses can’t be accomplished with MIDI single note-on keying, the system used in the majority of today’s keyboards.The XK-5 uses three mechanical contacts at different points in the keys’ travel. Each of these, in turn, triggers three virtual contacts, providing a discrete “note on” connection for every drawbar pitch in the same manner as the original nine-contact electro-mechanical Hammond® organ. The result is a fingers-to-music connection perfectly duplicating the response of a Vintage “B” while saving on weight and cost. Plus, the time-spread between these “note-ons” is programmable, as is the order in which the harmonics speak, allowing for totally unique variations in touch and response. As all the contacts receive and transmit MIDI data, every nuance of your performance can be captured into a DAW.

“The first thing that struck me was the action. I played a big Larry Young chord, and stretching and hitting that top note, it didn’t quite trigger all the way until I really pressed on it. That’s exactly what a B-3 does and what I expect as a B-3 player.”

– Jim Alfredson (Organissimo, Janiva Magness)

Completely Redesigned Key-bed: The XK-5’s keyboard action is built in-house, not sourced from a third-party manufacturer. It was designed to duplicate the heft, bounce, and key dip of a “new old stock” and well-maintained B-3™: No springy synth keys allowed! Master Hammond players who tested early prototypes confirmed that nothing comes closer to the feel and response they expect from a Vintage Hammond. Of course it has the “waterfall” key fronts critical to Hammond playing techniques such as palm slides and glissandos. Play the XK-5 alongside any other modern organ and we’re convinced you’ll find the difference stunning. Play the Xk-5 alongside a vintage Hammond and we’re convinced you’ll find the similarity stunning.

“The feel of the keyboard, it kicks back at you. It’s not dead, and it feels good. See, that’s what we’re looking for!”

– Dr. Lonnie Smith, legendary jazz organist 

“It’s like the feel of what I imagine it must have been like in 1968
when you put your hands on a brand new one. It feels great.”

– Chuck Leavell

All-New Sound Engine: The XK-5 employs new proprietary technology digitally recreating Hammond’s storied tone wheel generator with unprecedented accuracy and flexibility. Tone wheels were spinning discs on shafts, each with its own pickup pointing at the edge. The pattern of “teeth” cut into the edge of the wheel determined the pitch. Modeling and sampling are combined in an exclusive process to capture the frequencies of all 91 tone wheels found in the original organs, along with other important sonic details such as key click, Touch-Response Percussion™, vibrato-chorus, and more.

Tone wheel generators have become like rare violins or classic cars: Even though Hammond calibrated all instruments that left the factory to sound identical, no two are exactly alike after decades of use. To cover the extremes found in Classic Hammonds we’ve extended the range and programmability of both the overall generator characteristics (such as leakage and motor noise) and individual tone wheel behavior (such as the purity of the sine wave) to wide degrees. In addition to letting you perfectly duplicate different conditions of Hammonds—from showroom-new to road-abused (if that’s what you’re going for)—there’s the ability to recreate individual organs right down to the model, year, and serial number! Presets will capture the exact tonal qualities of famous artists’ instruments, from jazz great Dr. Lonnie Smith to Chuck Leavell (The Rolling Stones) to Gregg Rolie (Santana, Journey) and more.

Virtual Matching Transformer: In regards to the iconic Hammond sound, Tone-wheels and the Chorus-Vibrato scanner tell only a part of the tale. Our engineers’ research found all components in the signal chain play a vital role leading to the end product. The influence of the MATCHING TRANSFORMER provides a link to one of the Vintage Hammond’s most elusive qualities. All signals from the upper, lower, and pedal manuals passed through the matching transformer designed to “even things out” before the signal continued to the preamp. The transformer—a piece of iron with a coil wrapped around it—could “remember” some of its saturation based on how hard it had been working previously, thus affecting new notes played. Physicists call this hysteresis. Musically speaking, it affects how much “volume robbing” you hear and adds to what Hammond aficionados think of as the “breathing” quality of the organ. (The phenomenon is similar to why some recording engineers like transformer-equipped microphones and/or preamps for certain sounds.) In the XK-5, the matching transformer and its place in the signal chain is modeled precisely, and the saturation and hysteresis amounts are adjustable from barely-there to over-the-top. Like we said, we’re closing the final few millimeters of the realism gap.

MORE FEATURES

We didn’t stop there. Just a few of the XK-5’s more than 50 innovations and features include:
• Four full sets of Harmonic Drawbars plus pedal drawbars, just like on original Hammond console organs including the B-3
• 12 additional virtual tone wheels are devoted to harmonically complex pedal tones (i.e. more than just 16′ and 8′ sine waves), as found on Hammonds beginning in 1945.
• Custom tone wheel profiles available via download.
• Our best-ever Digital Leslie. Anything else is just a “rotary simulator.”
• Continuously variable Digital Leslie speed if desired.
• Dedicated octave shift / transpose buttons.
• Improved DSP-based overdrive complemented by vacuum tube preamp.
• Improved vibrato-chorus.
• Dedicated on/off buttons and amount knobs for reverb, overdrive, and assignable multi-FX.
• Lower B drawbars can alternately control 9 MIDI CC messages for external gear.
• Left and right ¼” outs can be used at the same time as Leslie output, for running the XK-5 through a real Leslie in parallel to stationary speakers, a subwoofer, or house P.A.
• More key-triggering modes for pedal-to-lower coupler (Manual Bass function).
• Firmware updatable via USB flash drive or directly from computer.
• Crisp new OLED display is more readable under different lighting conditions.

Of course we’ve retained the things that made working with the XK-3C and our compact SK-series keyboards a joy. Hold any button and the first page of parameters most relevant to it comes up in the display—holding the Leslie speed button for Digital Leslie settings, for example. This saves you a ton of menu-diving when customizing your sounds. New patch-naming and copying features also make your housekeeping even easier.
