7. ORGAN EDIT PARAMETERS
– Generator: select a tonewheel generator from this list. Each generator is based
on actual values as measured from real console organs of the B/C/A series.
– Generator Shape: select between OFF (no shaping) or 3 levels of CUT and 3
levels of BOOST. These will modify the amplitude chart of the generator values
according to different positions along the generator. This parameter does not
apply any equalization to the sound. Levels 1 can boost or cut starting from
wheel n. 25; levels 2 start from wheel n. 52; levels 3 start from wheel n. 72.
– Leakage: adjusts the background hum & hiss.
– Crosstalk: adjusts the amount of crosstalk caused by the analog circuitry. This
is a very important element of the tonewheel organ sound.
– Xtalk Shape: since the crosstalk consists of both bass and treble tones, this
parameter mixes between the presence of one or the other, left towards a
“rumble” noise, right towards a “brilliant” noise.
– Complex wheels: are special tonewheels only used for the first 12 tones wired
with the pedalboard. Unselecting this parameter will use standard sinus
tonewheels.
– Foldback on 16': the first 16 wheels wired to the keyboards are usually folded
back, thus starting from wheel n.13 rather than from wheel n.1. If you wish to
use the first 12 wheels on the manuals, uncheck this option but you should also
uncheck the Complex wheels.
– Resistor wires: are the small wires that in the vintage organ connect the
keyboards to the generator. This parameter offers three different values:
“Console: NEW”, as specified by the original B3 specifications; “Console: OLD”,
resulting in a more present low-end; “Spinet”, same as “Console NEW” but
without the foldback.
– Drawbar trims: the 9 parameters under this section can be used to adjust the
presence of each drawbar. This will apply on top of the actual drawbar
registrations for both the upper and the lower manual.
– Percussion settings: set the parameters of the percussion circuit such as the
level when it's on normal or soft, the decay time when it's on slow or fast, the
overall level, and the loudness loss when the volume tab is set to normal.
– Perc Paradise Mod: this is a “hack” that causes the percussion to never decay.
What's special in this is that if you activate the scanner vibrato effect, you'll
notice that the vibrato is applied to the rest of the drawbars but not to the
percussion tone.
– Other settings: here you can adjust the depth of the vibrato circuit and the mix
amount that affects the chorus settings, plus some parameters related to the
generation of the KeyClick noise.
– Preamp Bass / Treble: adjust the frequency response of the organ's built-in
preamp circuitry.
– Split Toggle and Note: use this to activate the split between upper and lower
manual, and to select the split point (lowest note of the upper part).
