Use a single-channel controller with Vintage B3 in Logic Pro for iPad
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.
In Logic Pro, choose an option from the Keyboard Mode pop-up menu in the Keyboard parameter section.
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.
Note: 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.
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 in the Keyboard parameter section.
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 in the Keyboard parameter section.
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 in the Keyboard parameter section.
Choose an octave value (+/– 2 octaves) in one or more of the Transpose Pedal, Transpose LM, or Transpose UM pop-up menus.
