Vintage B3 Organ Model controls
The Organ Model controls change the basic tonal quality.
Organ Model parameters
••
Maximum Wheels slider: Drag to set the number of tonewheels that are emulated. Reduce
the value to minimize the computer processing load. Reducing the value diminishes some
overtones, so keep the number high if you’re after an ultrarealistic simulation.
••
Tonal Balance slider: Drag to change the mix relationship of the higher and lower tonewheels.
Use positive values to achieve a lighter and brighter sound. Experiment with different tonal
balance and equalizer settings. See Vintage B3 EQ on page 414, for further information.
••
Lower Manual Volume slider: Drag to set relative levels between the upper and lower manuals
(and pedalboard).
••
Pedals Volume slider: Drag to set relative levels between the upper (and lower) manual and
the pedalboard.
••
Shape slider: Drag to alter the waveforms of the tonewheel generator, allowing you to produce
sounds that resemble the tones of Farfisa, Solina, or Yamaha organs. The Hammond’s tone
generators produce pure sine waves (albeit with a few artifacts), whereas some other organs
deliver distorted waveforms. The Shape parameter is placed after the filters that follow the
sine generators.
••
Move the Shape slider to the right to make the tone brighter (and louder).
••
Move the Shape slider to the left to make the tone duller (and softer).
••
Bass Filter slider: The tone of the pedal draw bars can sound bright, within the context of the
combined upper/lower/pedal sound. Adjust to circumvent this issue, and to suppress the
treble of the bass register. At the maximum position you will only hear a solid bass organ
fundamental in the bass register.
••
Ultrabass switch: Turn on to add another low octave to the playable range of both the upper
and lower manuals.These additional low octaves, and the ability to independently transpose
both manuals (see Transpose keyboard zones by octaves on page 402), are not available on
the original B3.
