Use multiple or multichannel controllers with MainStage Vintage B3
By default, Vintage B3 receives the notes for the upper and lower manuals, and for the
pedalboard, on three consecutive MIDI channels, mapped as follows:
• MIDI channel1:You play the upper manual sound.
• MIDI channel2:You play the lower manual sound.
• MIDI channel3:You play the pedalboard sound.
This allows you to simultaneously play Vintage B3 with up to three MIDI controllers.
You can also use a single-manual master keyboard—with different keyboard zones, or a
keyboard split feature—that sends data on different MIDI channels to address all three
Vintage B3 sounds simultaneously. Each keyboard zone can be transposed independently.
See also Set the MainStage Vintage B3 MIDI control mode. You can use any of your MIDI
interface inputs for your master keyboard or pedalboard. Regardless of the input devices
used, the only relevant factor is the MIDI send channel.
Note: See the user manual for your master keyboard to learn how to set up splits and
zones or how to set its MIDI transmission channel (often called TX Channel).
Set the keyboard mode
There are three keyboard modes: single, split, and multi.
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 Single, Split, or 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.
Change the default MIDI channels
Changing MIDI channels can be useful when you perform live and require quick access to
another sound module.
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 Multi.
3. Change the channel numbers for the upper, lower, and pedal manuals.
Set keyboard zones
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. 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).
