Logic Pro Vintage B3 Organ Model controls
The Organ Model controls change the basic tonal quality.
Organ Model parameters
• Maximum Wheels slider: Set the number of tonewheels that are emulated. Reduce the
value to minimize processing load. Reducing the value diminishes some overtones, so
keep the number high if you’re after an ultra-realistic simulation.
• Tonal Balance slider: Change the mix relationship of the higher and lower tonewheels.
Use positive values for a lighter and brighter sound. Experiment with different tonal
balance and equalizer settings. See Logic Pro Vintage B3 EQ controls, for further
information.
• Lower Manual Volume slider: Set the relative level between the upper and lower manuals
(and the pedalboard).
• Pedals Volume slider: Set the relative level between the upper (and lower) manual and
the pedalboard.
• Shape slider: Alter the waveforms of the tonewheel generator to produce sounds that
resemble the tones of Farfisa, Solina, or Yamaha organs. The Hammond 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: Adjust to suppress the treble of the pedal draw bars which can sound
bright within the context of the combined upper/lower/pedal sound. At the maximum
position you hear only a solid bass organ fundamental in the bass register.
• Extended bass switch: 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, are not available on the original B3.
• Ultrabass switch: Turn on to disable duplication of the 16” drawbar in the lowest
octave. Turn off to mirror the original B3 behavior. The on position results in a sound
that resembles that of early tone wheel organs like the B, BV, and BCV, which had no
dedicated tone wheels with a complex waveform for the pedal. This is also known as
“Bass all the way down”. See Use multiple or multichannel controllers with Logic Pro
Vintage B3.
Note: Ultrabass and Extended Bass can be combined, but Ultrabass has no effect on
the added lowest octave. This octave always has a duplication of the 16” drawbar tone.
