Vintage B3 MIDI setup overview in Logic Pro for iPad
Vintage B3 is unique among the included instruments in that it can be played with three simultaneous controllers—namely, a MIDI bass pedal unit and two 73-key MIDI keyboards. This mirrors the two 73-key manuals (organ terminology for keyboards) and the 2-octave pedalboard configuration of the original B3. See Use multiple or multichannel controllers with Vintage B3 for more information.
Vintage B3 can also be played with a standard 61-key (5 octaves C to C) MIDI keyboard. See Use a single-channel controller with Vintage B3 for more information.
Vintage B3 also emulates B3 preset keys—the lowest octave of attached MIDI keyboards can switch between Vintage B3 registrations. This matches the behavior of the original B3, which features a number of inverted (black) keys in the lowest octave of each manual. These inverted keys are used as buttons that recall preset registrations (a preset of your draw bar settings). See Use Vintage B3 preset keys.
For information about setup and use of dedicated MIDI draw bar controllers, see Set a Vintage B3 MIDI control mode.
