Use multiple or multichannel controllers with Vintage B3 in Logic Pro for iPad
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. 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).
There are three keyboard modes: single, split, and multi.
In Logic Pro, choose an option from the Keyboard Mode pop-up menu.
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.
Changing MIDI channels can be useful when you perform live and require quick access to another sound module.
In Logic Pro, choose Multi from the Keyboard Mode pop-up menu.
Change the channel numbers for the upper, lower, and pedal manuals with the Pedal, Lower, and UM MIDI Ch pop-up menus.
In Logic Pro, choose Split from the Keyboard Mode pop-up menu.
Tap the StLMSP and/or the StUMSP button.
Choose a note name/number in the Split Point Pd/LM pop-up menu and/or the SP LM/UM pop-up menu.
Note: 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).
You can make transpositions that are independent of the global Vintage B3 Tune parameter or transposition features of Logic Pro. These 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.
In Logic Pro, choose Split from the Keyboard Mode pop-up menu.
Choose an octave value (+/– 2 octaves) in one or more of the Transpose Pedal, Transpose LM, or Transpose UM pop-up menus.
