Use a single-channel controller with Vintage B3 in MainStage
If you don’t have a master keyboard that allows multichannel transmission, you can use a MIDI keyboard that is capable of transmitting on only one MIDI channel. You can use Vintage B3 Split parameters to split the keyboard in order to play upper, lower, and pedal sounds in different keyboard zones. Each keyboard zone can be transposed independently.
There are three keyboard modes: single, split, and multi.
Single: Uses the entire keyboard. You can only play the upper sound.
Split: Divides the keyboard into two. You can play the upper and lower sounds in different keyboard zones.
Multi: Divides the keyboard into three. You can play the upper, lower, and pedalboard sounds in different keyboard zones.
Technically, Vintage B3 remaps the incoming single-channel MIDI data into two or three MIDI channels when either split or multi keyboard mode is active.
In MainStage, click Main in the control bar, then click the Split button at the lower right.
Set the switch to the left of the keyboard in the central display to Single, Split, or Multi.
Changing MIDI channels can be useful when you perform live and require quick access to another sound module.
In MainStage, click Main in the control bar, then click the Split button at the lower right.
Set the switch to the left of the keyboard in the central display to Multi.
Change the channel numbers for the upper, lower, and pedal manuals.
In MainStage, click Main in the control bar, then click the Split button at the lower right.
Set the switch to the left of the keyboard in the central display to Split.
Horizontally drag the split icons to create the pedal/lower zone and the lower/upper zone.
If you select the same value for both split points, the lower manual is turned off. If the lower/pedal split is moved above the upper/lower split, the other split point is moved (and vice versa).
In MainStage, click Main in the control bar, then click the Split button at the lower right.
Set the switch to the left of the keyboard in the central display to Split.
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 Vintage B3 preset keys when split keyboard mode is active.
