MiDisp. To change display ID, you have to select the display by pressing its button
first. Then enter command #914, and the display will show current device ID,
waiting for new digits. Possible values are from 00 to 99. This parameter is
associated with the display itself, and does change when you replace the module to
another MBBS input, or another position in a chain.

Display ID show - #920
You can check display IDs of all MiDisp modules in the system at once. First you
have to press a button of any LCD in the chain, and then enter command #920.
Then all displays connected to MRG will show their current display ID.
7.8.5
Display blink - #918
This is simply to make the MiDisp blink for a while. If you have chain of displays,
they will blink in a sequence determined by their position in the chain.

KEYPAD - numeric entry for user MIDI settings
Small keypad, resembling the ones used in phone sets, is all you need for changing
every setting available in MBBS. When not in edit mode, buttons 0-9 work exactly
like any music keyboard, playing notes if default setting was not changed. Button
"#" works like the last (64th) pin in contacts connector on-board MBBS. It brings
the system in EDIT mode. If MiDisp module is connected, it is clearly indicated
there. To quit from EDIT mode without changing anything, for example if "#" was
pressed by mistake, simply enter "0". There's no command starting with 0, so it
immediately returns to normal playing mode.
The KEYPAD, as setup entry, does not have to follow the rule of "only 2 keyboards
in a chain". It may be connected at the end of 2 BBS-1K chain and it will work
correctly. The channel, event, and starting note of the KEYPAD will be the same as
2nd BBS-1K in the chain, but this in any way des not disturb the KEYPAD in correct
function as setup keypad.
The electronic board mounted at the back of the keypad (since version 7.0) allows
to connect one rotary encoder, called sometimes "endless potentiometer". It is
treated like any other POT input, meaning it can be assigned to any possible event.
Most obvious use for example is Program Change knob (event 129), but it may be
global transposition, channel shift, or simply any Continuous Controller.
The encoder used must have no detents, or 2 detents per pulse. If 1 detent per
pulse is used, every step of the encoder will result in 2 MIDI messages, crossing 2
steps. The encoder must be soldered to 3 empty pads by the side of 4-way scanner
connector. Pinout is the same as in encoder itself, with common lead at the middle,
and pulse inputs at the sides.
