The B5 Organ V3

Based on real tonewheel samples and fully modeled: from the tonewheel pickups and the AO-28 amp to the resistive wires, to the drawbars and key contacts... Everything has been carefully measured on different models and adjusted to match real organs.
The true sound of an organ with the flexibility of synthesis.

A Hybrid Approach

Hammond organs are complex beasts, full of wires and mechanical parts. Until now, the best renditions (short of a real organ) were made using pure synthesis, mainly because the organ works using a set of 91 frequencies that are connected via contactors under each key and whose volume is controlled by the drawbars. Sample based libraries consist of stacking drawbar samples at the same time. This works, but causes a major problem: sometimes you play the same frequency twice and because of phase cancellation, you never get the same sound twice when you press the same keys. We have found a way using the 91 frequencies synthesis approach, but with real samples, which allows you to enjoy the best of both worlds: a real recorded organ tone plus the real mechanical behavior but with the added benefits of functioning drawbar controls and synthesis tweakability.

Sample based synthesis

There are things in the Organ sound that can't be faked, and it's the tonewheels, the keyclicks and the vibrato scanner, so we sampled them.

We then meticulously reproduced the whole signal chain: tonewheel pickups, resistance wires, AO-28 frequency response, drawbars, swell pedal, percussion circuit, as well as all of the knobs and controls available on a real organ. Even the small wiring and electrical peculiarities have ben reproduced like foldback, internal noise, leakage and even more complex ones like tone control, loudness robbing, voltage stealing, etc.

Rotary Speaker Simulation

Version 3 is an entirely new Leslie simulation, much more detailed and true to the 122A recordings.

You can choose between a few different Leslie models for each rotor, a 122, a 147, a 3300 and a few other variations.

It is also completely adjustable: microphone positions, angles, distance, and volume, pan, speeds and acceleration times can be modified independantly for each rotor.

We added three new features: driver distortion, microphone bleed and room simulation and combined with our V3 model, they make for an ultra realistic Leslie sound.

Hundreds of models

All of the tonewheel organs sound different, each of them has a particular voicing, and that's mostly due to the distance between the tonewhels and pickups but also to the aging of the capacitors.

With the help or Kon Zissis that has been servicing and measuring organs for many years, we were able to incorporate a list of 150 organ voicings, from many different organ models (A, AV, B, B2, C2, BA, BC , CV, B3, C3, A100, RT3 and a few others).

We also sampled 4 iconic models (1968 B-3, 1960 C-3, 1969 C-3 and 1965 A-100) and you can switch between their different tonewheel sounds.

The combination of these, the tweaking of the voicings and the manual tapering options allow you to virtually get any organ model in any shape possible.

FX Panel

On top of our Leslie tube saturation, we added a panel of 7 FX.

That includes a chorus, a phaser, a delay, an overdrive, a fuzz a wah that can be an auto-wah and a reverb that can be wether a spring, a plate or a real room.

These FX are pre Leslie, except for the reverb that can be pre or post.

Now you can really recreate the sound of any organ song, including the progressive rock ones!

Tube saturation

The tube saturation on a Leslie 122 is very different from what you can hear on other tube amps.

We completely redid it in the version 3 to match it even better to real recordings.

Advanced Percussion System

The percussion on an organ is not just an addition of samples, it is a general volume decay envelope triggered by the first note you play, which is not restarted until you release all the keys.

We recreated it so meticulously that you can hear a percussion sound when you turn it on or change from second to third! You can even customise the time, volume and frequency to make it sound like "paradise".

It is also completely customizable, you can edit the volume for the normal and soft settings and the the decay times, decide on which harmonic is played or control the recharge time.

Real key contact modeling

There are 9 electric contacts under each key, and each of them produces a small click, but they don't all happen at the same time, also the intensity and timbre of each click depends on the phase of the tonewheel signal when the circuit is closed.

Mr Hammond hated them, but a Tonewheel organ would not be one without them.

We completely recreated that model for the version 3, we simulate the progressive 9 contacts with velocity and the variation of timbre and volume is now based on the current phase of the tonegenerators.

You can also control their overall volume and timbre.

Organ modifications

Every organ player likes to tweak his instrument, so every modification that organists can do is available.
- Paradise button
- Percussion always on
- Percussion volume decrease
- String Bass
- Foldback removal

and many oher tweaks... but without having to solder or unsrew the whole thing.

All three keyboards

On a real organ, there are 3 keyboards, two of which are almost identical except for the percussion system, and the bass pedals.
You can choose to use 3 different MIDI channels, one for each keyboard or you can use the split to have all three on one keyboard.

In version 3, we decided to extend the capabilities of the Bass pedal manual.
On a real organ, the Bass Pedals drawbars are a fixed combination of 8 frequencies, but in the V3, we give you access to that mix and the first 12 tonewheels that produce complex tones can also be filtered out to be closer to a sine wave.

We also extended the range of the Bass manual to 32 notes to match the RT3 model.

If you don't have pedals on your controller, you can also remove the bass foldback for the Upper and Lower manuals to get access to the deep bass without them.

You can also enable the stringbass mod with control over the sustain.


In the version 3, we completely reworked the preset system.
They are now global and will save everthing, but you still have access to around 200 drawbar presets that you can load, save, delete or assign to the preset keys (upper and lower), and these include the most used Jazz, Gospel and classical presets.

The preset keys (Bleck Keys to the left of the range) can also be customised and will allow you to easily change drawbar settings while playing.

MIDI assignment and controllers

Every element of the interface can be assigned to any MIDI CC and Channel easily using our assignment panel or our MIDI learn function.

To make things easier, we included a few mapping presets for the most common organ clone controllers, this includes, the XK series, all Nord keyboards, the Crumar, the HX3, the B4D and others.

We included most tweaks required by some controllers like the inversion of the drawbar movement or the toggle for the leslie speed.

The volume pedal is a crucial element when playing the organ and we give the possibility to adjust the curve and range of the volume and filter affected by the pedal.

Version 3 changelog:

- Interface redesign, upon user request, the switches are now arranged like on a real B3.
- New preset system. Saving a preset is now global and will save everything, including the voicing and the tonewheel model.
- Separation of the “brake” and Leslie speed features, they can now be controlled separately.
- To add variety, the voicing is now separate from the tonewheel models.
- In collaboration with Kon Zissis, we incorporated a new electrical chain model and were able to add about 150 Voicing models (A, BC, A100, B3, C3, RT3) that he measured over the years from various models and using different capacitors, old and new and different voicings, following the different Hammond technicians regulation.
- These voicings can be changed manually using a large table.
- To go with these voicings, we offer the choice to add/remove manual tapering or even to use a hybrid manual tapering that will get older models like the A to have both bass and treble (will explain that in detail).
- New “TONE CONTROL” knob that simulates the tone control potentiometer present inside the real Hammonds that allow to control the overall brightness of the organ, it’s not a simple filter, it’s a voicing element that acts on the 91 tonewheels before the whole drawbar system.
- New FX panel with Chorus, Phaser, Delay, Wah (and auto Wah), overdrive and fuzz that come between the tone generation and the Leslie Amp. You can also choose between a spring reverb, a plate or a real room and you can put it pre or post Leslie.
- The tube distortion has been completely changed to match the AO-28 amp distortion.
- Entirely new Leslie simulation, much more detailed and true to the 122A recordings. You can now mix (volume and pan) the Leslie signal with the DI and also an additional guitar cab. You also have control over the crossover filter to simulate the aging of the capacitors.
- Addition of the "room simulation" that allows you to put the Leslie in a less Dry environment.
This update also includes the following new features that are available independently for each speaker (ie, Horn and Drum):
- Speaker distortion
- Pan
- The acceleration and deceleration curves have been reworked and you can also add some speed variations to replicate the imperfections of the Leslie motor.
- Microphone position around the Leslie
- Microphone angle (from mono to very wide stereo)
- Microphone distance, from 2’ to 36’ (5cm to 90cm)
- Microphone bleed
- Memphis option (one of the speaker’s rotation is just stopped while the other one is still functional)
- Fixed or natural brake position.
- An amplitude modulation enhancer for a stronger wobbling effect.
- The deflector can be removed from the Horn and the Back panel can be removed from the Drum.

- New MIDI panel with control over the inversion, the toggle, MIDI C and MIDI Channel for each element.
- MIDI learn function for each element, all you have to do is click next to the control name and move a MIDI controller.
- You can now save and reload your MIDI Mapping.
- You can now use the Pitch Ben as a MIDI CC (CC127) to control whatever you want.
- Improved vibrato and chorus thanks to a new phase lock model.
- Pedal drawbars CPU efficiency improved.
- Pedal keyclick fixed to match the real ones.
- Pedal range extended to 32 notes to match the RT3 model range.
- CPU load reduced on the swell pedal.
- Control over the pedal harmonic mix
- Added mod for sine sound on the 11 first complex tonewheels
- Added MOD to have the percussion playing all the time with no volume drop.
- Added control over the crosstalk (leakage)
- Added control over the Keyclick Brightness.
- The click volume is now smooth and can be changed in real time.
- The acoustic sound of the pedals is now from real pedals and not manual keys anymore.
- Added the ability to disable the foldback.
- Click sound improved with much accurate volume and tone variation.
- Better control over the drawbar preset list which can now be organized, modified, saved, loaded and reset.
- Addition of a panic button that will stop all running Tone generators.
- Better control over the black keys presets, they can now be deactivated for users that accidentally triggered them while playing.
- Extended the pedal range to 32 notes to account for the RT3 pedal range
