So, easiest is to set both keyboards to MIDI channel 1, and
plug in the upper-register keyboard to MIDI A, and the lower-
register keyboard to MIDI B.
MIDI controller messages are processed on the "Ctrl" MIDI
channel. Usually this is the same channel as you use for the
upper keyboard. So, with the upper keyboard you also can
select the Preset, and send other controllers. If you don't want
the B4000+ to react on these controller messages, set the
"Ctrl" MIDI channel to off.
MIDI data is also transferred via USB. The MIDI
channels on USB are fixed to channel 1 (upper
register and controller), channel 2 (lower register)
and channel 3 (pedal register). All incoming data
from the MIDI plugs is transferred to the PC by USB,
so you are able to record them on your sequencer.
The "Oct" line is used to transpose the registers by one octave
up or down. With "Trp" you also can transpose all registers by
half tone steps.
The Split-function is enabled automatically as soon as you
select the same MIDI channels for two registers, for example,
by selecting MIDI channel 1 for Upper and also Lower. Then
the splitpoint is selected by the split-note.
