73-KEY VIRTUAL TONEWHEEL ORGAN/KEYBOARD WITH 4 SOUND ENGINES

The Hammond name commands respect. It is synonymous with classic tonewheel organs like the B3, which played a massive role in the musical revolution of the 1960s and 70s. In the digital age, Hammond has taken a leading role in developing cutting-edge "clonewheel" organs that deliver those legendary organ sounds, alongside all the other essential keyboard instruments needed for any gig or recording session. The SK Pro represents the latest generation of Hammond's all-in-one organ keyboards. Equipped with higher-resolution samples than previous SK series instruments and featuring four robust sound engines that can be used individually or in any combination, the Hammond SK Pro raises the bar for breathtaking sonic realism.

Like a true Hammond, the SK Pro naturally features state-of-the-art, authentic organ sounds. These are provided by its newly designed Drawbar Organ section, derived from the flagship Hammond XK-5. The SK Pro's industry-standard Hammond sound is generated by the powerful Modeled Tone Wheel 1 (MTW1) engine, complemented by a special system that emulates the matching transformer of a vintage Hammond, while a newly developed Virtual Multi-Contact function replicates the keyboard response of those coveted models.

The SK Pro houses Hammond's next-generation Digital Leslie, offering deeper authenticity—including rotor airflow simulation—to faithfully reproduce the unique Leslie cabinet sound and its three-dimensional swirling effect. A new modeling system delivers characteristic tube warmth and a gritty growl when pushed. In addition to the tonewheel engine, Hammond's Wave Composition system adds voices from vintage Italian, British, and Japanese transistor combo organs—instruments that have made a major comeback. Furthermore, the SK Pro offers a comprehensive range of pipe organ sounds, including a brand-new selection of theatre organ voices. No matter the genre, the SK Pro is gig-ready.

The SK Pro also features an all-new Piano/Ensemble engine with a wide variety of keyboard and other instruments, including acoustic and electric pianos, brass, reeds, strings, choirs, and percussion. High-resolution samples of the world's finest grand pianos are a highlight, particularly the stunning new "S" sample of a legendary European grand piano. And for the first time in an SK-series keyboard, all piano and ensemble voices are fully editable.

The SK Pro packs a powerful physical modeling synthesizer that faithfully reproduces the sounds of classic analog synths. The Mono Synth engine offers six different oscillator configurations, along with Filter and Amplitude controls, allowing you to create and tweak sounds in real-time—just like on a vintage analog synth.

The SK Pro is equipped with a powerful onboard DSP effects engine. Each of the SK Pro's four voice sections can be assigned overdrive and two types of comprehensive DSP multi-effects. Overdrive options include Tube, Solid-state, Clip, and EP Amp, while the two multi-effect engines offer Tremolo, Wah, Ring Modulator, Compressor, Phaser, Flanger, Chorus, Delay, and Auto Pan. The SK Pro introduces "Combinations" to the SK series, allowing you to create patches using any or all of its four sound sections, complete with your desired performance parameters. You can also assign external MIDI instruments to these combinations. Combinations prepare you for any performance and can be modified instantly. Using the four Allocation buttons in the center of the keyboard, you can recall any part of a combination in real time, effectively giving you the equivalent of four separate keyboard instruments.
