The signal was re-amped though a Fender Deluxe Reverb and recorded via a Sennheiser e906. Both signals were run through Grace M101 preamps. A Hammond M3 Organ combines the last two harmonics into a single drawbar, this note was omitted. Instead, a "digital foldback" teqchnique was used to extend the harmonics of the Hammond M3 to be similar to that of a Hammond B3.

The organ's range was augmented to be similar to that of a Hammond B3. This was accomplished by using the Organ's pedal tones to add the lower octave notes.

The Leslie Speaker simulation was designed to mimic a real Leslie. The signal is split to a virtual bottom rotor and virtual upper rotor at around 600 Hz. Vibrato, chorus, and panning processing are used to simulate the rotation of the rotors. The upper rotor spins between 48/409 RPM's and the bottom rotor spins between 40/354 RPM's. Bottom rotor rotation can be bypassed. The Leslie simulation can also be bypassed.

B3 effects where also digitally simulated and these include percussion, vibrato, and key click. Vibrato scanner is similar to that of a B3 and includes vibrato as well as vibrato+chorus. Key click was simulated by adding random noise to the attack and release samples. Some key click can be heard in the original samples but the effect has been exaggerated. Percussion was simulated in VST as it is in real life: a higher amplitude, percussive decaying sound is added to the instrument via the 2nd or 3rd harmonic. The plugin also includes reverb, braking, variable acceleration, drive/distortion, smoothing, adjustable stereo panning, key-splitting, and preset switching. Version 2.0 also includes amplifier sims based on vacuum tube simulations and speaker EQ curves. An extra drawbar has also been added to the organ between the 4th and 5th drawbars (x), equivalent to the 5th harmonic of the sub-fundamental or a 3 1/5' pipe length.


The instrument was equalized to sound slightly more aggressive than a typical Hammond organ and therefore has the potential to stand out more in a mix. This can be adjusted with the "smoothing" knob, which will attenuate some of the harsher frequencies, and (in version 2.0) the smooth/bright switch and angle knob.
Inside the VST the amp and speaker signals go through preamp/gain staging whether or not the Leslie bypass is engaged. The plugin requires a decent CPU - at least an Intel Core I3. This is because internally each harmonic is being summed for each note - which can include things like percussion and key click - meaning that each note requires upwards of 22 voices. Internally the VST is capped at 330 voices, which is equivalent to 15 notes of polyphony. The voicelist also requires extra processing power, as unlike a piano or other percussive instrument, each note can be sustained indefinitely, and thus newer notes must work around this limitation.

The plugin also does a fair amount of internal eq and sonic shaping depending on the preset. A great deal of time was spent experimenting and finding useful drawbar settings and eq combinations, and vacuum tube sims. There are 95 built-in presets modeled after classic Hammond Organ drawbar settings and famous songs.

The memory footprint of the plugin is around 400 MB. All of the plugin's samples are loaded into memory upon loading as the plugin is primarily comprised up of looped samples, padded out with short attack and release samples. This means that this particular plugin is not dependent on a fast hard drive as it does not need to buffer samples during execution.

The plugin is designed to work with VST AU and AAX native versions and a Kontakt version was not created. This is because the plugin relies heavily on internal programming - for everything from the Leslie simulation, to sample fold-back, to vacuum tube sims - that would be impossible to replicate with the Kontakt player's simple scripting language.

This VST is, essentially, a hybrid between a Hammond M3 and B3 with a more aggressive sound. It is meant to sound a bit unique to already existing plugins and simulations, but with the wide range of parameter combinations, many sounds are possible.
