J1 - LED-buttons 1-8
J2 - LED buttons 9-16
J3 - LED buttons 17-24
J4 - connector to MBBS

The pins of each LED-button connector are 
interlaced for easier installation. Odd pins 
are LED outputs, and even pins are button 
inputs in the following manner: pin 1 - LED 
1, pin 2 - button 1, pin 3 - LED 2, pin 4 - 
button 2, etc. This is shown in the 
schematic on the left. Each 16-pin 
connector layout is the same. 

Out of the box it generates note-on and note-off messages with momentary 
buttons and LEDs (independent mode), most useful as register control in organ 
emulator. But it can be converted into a few variations, finding its way toward other 
non-typical uses. Possible controls are:

 7.6.1 

Split point - #905

This is different kind of split than the one described in chapter 5.5 and is 
independent of that one. So you can use both kinds of split at one time, and they 
can be at different points, even though it may not make much sense. The 

#905 

split controls only button's behavior, and not actual MIDI data transmitted by MBBS 
to MIDI OUT socket. Each split can work in different mode, with independent or 
dependent buttons, generating CC values or contact on/offs. To have different MIDI 
events or channels in the splits you have to also split it logically, using procedure 
described in 5.5. 

 7.6.2 

Independent mode - #908

In independent mode, all buttons work without interactions to each other. If a 
button is pressed, associated LED lights, and note-on is sent by MBBS (only if it is 
configured to send notes on this input - sequence #2131). Another touch of this 
button and LED turns off and note-off is sent. To set this mode on a split, you have 
to select it first by pressing one of the buttons in that split.

 7.6.3 

Dependent mode - #909

In dependent mode, there can be only one LED active at a time. If you press 
another button, it will light up and any one that was previously lit, will now turn off. 
In this mode only note-on messages are generated, there is no note-off. This is 
most useful for selecting presets on MIDI instrument, like described in chapters 
5.2.3., and 5.2.8. To set this mode on a split, you have to select it first by pressing 
one of the buttons in that split.
