• Filter Age slider: The high frequency output signals of the B3’s tonewheel generators
are passed through bandpass filters. The center frequency of these filters varies as the
capacitors (used for filtering) get older. You can use the Filter Age parameter to alter
the center frequencies of the filters, thereby emulating aging capacitors.
Note: This colors the sound of the jitter applied by Random FM and the background
noise resulting from leakage. This parameter also influences the intonation of the organ,
if you use a pitch bend.
EVB3 Organ Parameters
The Organ parameters alter the basic tonal quality of the EVB3.
Organ parameters
• Max Wheels slider: Determines the number of tonewheels that are emulated. Reduce
the value to minimize processing load, as emulating all tonewheel generators (even if
unused) consumes significant CPU processing power. You should note that reducing
the value will diminish some overtones, so keep the number high if you’re after an
ultrarealistic simulation.
• Tonal Balance slider: Changes the mix relationship of the higher and lower tonewheels.
Use positive values to achieve a lighter and brighter sound. Feel free to experiment
with different Tonal Balance and Equalizer settings. See Using the EVB3’s Integrated
Equalizer, for further information.
• Shape slider: You can subtly alter the waveform of the sounds emanating from the
tonewheel generator using the Shape parameter. While the Hammond’s tone generators
produce pure sine waves (albeit with a few artifacts), other organs deliver distorted
waveforms. You can use the Shape parameter to produce sounds that resemble the
tones of Farfisa, Solina, or Yamaha organs. The Shape parameter is placed after the
filters that follow the sine generators.
• Move the Shape parameter to the right to make the tone brighter (and louder).
• Move the Shape parameter to the left to make the tone duller (and softer).
