Vintage B3 Condition controls in Logic Pro for iPad
Technical limitations of electromechanical draw bar organs, with tonewheels, can cause some strange tonal artifacts, such as crosstalk. These quirks form an integral part of the B3’s charm. You can adjust a number of parameters to define the age and condition of your Vintage B3.
Organ Condition parameters
Filter Age knob and field: Set the center frequencies of the filters to emulate aging capacitors. The high frequency output signals of B3 tonewheel generators are passed through bandpass filters. The center frequency of these filters changes as the capacitors (used for filtering) get older.
Note: This colors the sound of the jitter applied by Random FM and the background noise resulting from leakage. Filter Age also influences the intonation of the organ, if you use a pitch bend.
Leakage knob and field: Add a “breathy” quality to your sound—the result of crosstalk between all tonewheels—including the tonewheels of notes that you don’t play.
Drawbar Leak knob and field: Set the minimum output level of the draw bars when they are at their minimum positions. The B3 tonewheel generators aren’t completely quiet, even if all draw bars are at their minimum positions. This is due to leakage of the tonewheels, causing crosstalk at the output.
Use the minimum setting to completely eliminate draw bar leakage.
Use the maximum setting to make draw bar leakage clearly audible.
Crosstalk knob and field: Set the crosstalk level. There are two tonewheels that are four octaves apart for each key (pitch), on each rotating shaft. The signal of the lower wheel has a small amount of audible crosstalk, induced by the higher wheel, and vice versa. For more information, see Tonewheel sound generation. Because crosstalk is audible only on certain B3 tonewheels, any “rumble” when chords are played is avoided.
RandomFM knob and field: Simulate irregular rotation of tonewheels in an old B3. If the tonewheel generator of a B3 is clean, all frequencies are even and in tune. The three-fold decoupling of the tonewheels—via springs, flexible couplings, and flywheels—is effective, but it can’t compensate for irregularities that come with dirt and grease in the driving gears. A gradual build-up of grime in the mechanism makes the tonewheel assembly turn unevenly on its axis. This irregular rotation is transmitted to the tonewheels, and therefore, the higher frequency ranges of the sound.
