KeyB Duo organ MkII

Latest in modeling technology

The KeyB Duo uses DLQ's own unique "Physical Instrument Modeling" algorithm. With PIM you hear an exact clone of the classic tonewheel organ. The result is the natural sound of tonewheels that can't be obtained when using traditional sampling. PIM provides the best reproduction of the sound produced by a tonewheel organ, including cross talk, tonewheel flutter, electric hum and octave tapers.

All new rotary simulation

Maybe you don't have one or it's not convenient to take a rotary speaker with you. Don't worry! The new KeyB Rotary Simulation is incredibly realistic. It's so good you'll have to look twice to see where the rotors are, this is because of the PIM engine.

Easy to play

When you sit down at the KeyB Duo, all you have to do is turn it on and play. Everything you need and are familiar with, on a classic tonewheel organ, is there right where it belongs. No confusing menus or LCD screens full of features that you most likely don't or won't use. After all, it's an organ.

Full set of drawbars

If you have been playing a classic tonewheel organ, then you will feel at home with the KeyB Duo. It has two full sets of 9 drawbars for the upper keyboard, two full sets of 9 drawbars for the lower keyboard and 2 pedal drawbars.

Waterfall keyboards

Along with the best sound and being easy to play, the KeyB Duo has two heavy-duty 61-note keyboards with the feel of an organ, not a synthesizer or cheap portable keyboard. If you play pedals, then you can purchase the optional 25 full-sized console pedals. The KeyB pedals are heavy-duty and are same radius as the classic tonewheel organs, which makes playing the pedals feel right.

Harmonic percussion

Located right where they belong are the rocker tabs to control the 2nd and 3rd harmonic percussion. Soft and normal percussion volume, fast and slow percussion attack.

Volume, vibrato and chorus

You can use vibrato/chorus independently for the upper and lower manuals or together just like the classic drawbar organ. Use the familiar rotary control to select all three Vibrato and Chorus settings.

Upper realtime controls

The upper manual realtime controls include transpose, volume, reverb, overdrive, keyklick, crosstalk, pitch bend, modulation and switches for local/MIDI control and upper manual drawbar set A/B.                     

Lower realtime controls

The lower manual realtime controls include bass, treble, rotary control and switches for local/MIDI control and lower manual drawbar set A/B, and bass pedal controls including local on/off, bass to lower on/off, string bass on/off and string bass decay.

External speaker ready

The KeyB Duo can be connected to either a keyboard amplifier or if you need more power, connect it to an external rotary speaker via the line outs.

MIDI and Controllers

The KeyB Duo has MIDI in and out for the keyboards and the pedals, and inputs for a rotary switch, expression pedal and sustain pedal. The Gospel set switch allows you to invert the upper and lower drawbar sets. A USB connector is available for easy software upgrades.


The KeyB Duo organ automatically supports 115 - 230VAC 50/60Hz mains power.
