Transpose keyboard zones by octaves
1. In MainStage, click Main in the control bar, then click the Split button at the lower right.
2. Set the switch to the left of the keyboard in the central display to Split.
3. Choose an octave value (+/– 2 octaves) from the Pedals Transpose, Lower Transpose,
or Upper Transpose pop-up menu.
These transpositions are independent of the global Tune parameter or transposition
features of MainStage. They also have no impact on the preset keys which is
particularly important when you want to use preset switching. See Use MainStage
Vintage B3 preset keys when split keyboard mode is active.

The Hammond story can’t be fully told without discussing the rotor cabinets manufactured
by Leslie. In fact, playing the B3 organ without a rotor cabinet is viewed as something of
a special effect these days. Vintage B3 not only simulates the speaker cabinet itself, but
also allows you to change the listening position by placing virtual microphones in different
locations.
Some of the speaker cabinet models are mathematically simulated, and others use a
recording of the spatial characteristics of the speaker. The latter is known as an impulse
response. Detailed information on impulse responses can be found in the Space Designer
section of LogicEffects Help. If you’re unfamiliar with the concepts of the Leslie rotating
speaker cabinets, see The Leslie cabinet.
The Leslie rotation speed control is shown at the lower-left corner of the Vintage B3 Main
and Rotor Cabinet windows. Advanced speed controls are shown in the central display
when you click Rotor Cabinet in the control bar.
The advanced Leslie rotating speaker cabinet controls are useful for specialized sounds, or
when you are creating realistic emulations. See MainStage Vintage B3 Cabinet parameters,
MainStage Vintage B3 Motor parameters, and MainStage Vintage B3 Brake parameters.
