used velocity settings in nonvolatile memory. This should be used only during 
installation, when you want to set default velocity of notes after each power up. For 
expression and frequent usage, control the velocity by assigning #2139.

 5.2.24 

Single keyboard transposition buttons - #2150 to #2153

A potentiometer, or special switch input can be assigned as setup buton for 
keyboard transposition. There are 4 of them to choose and their event numbers are 
150 to 153: one semitone up (150), one semitone down (151), one octave up (152) 
and octave down (153). Pressing such button (shorting input to ground) will affect 
only the last played keyboard, and this setting will be memorized in non volatile 
memory. Go to chapter 5.1.2 for more details.

 5.2.25 

Channel set buttons - #2154 & #2155

MIDI channel of the last used keyboard or potentiometer can be changed in single 
steps up or down, by using these special events. They can be assigned to any pot, 
or special switch input. Event 154 rises the channel number of last played 
keyboard, or last turned pot by one up, while event 155 does the same, but one 
channel down. The settings are stored in non volatile memory.

 5.2.26 

All keyboards transposition - #2156 to #2159

This is similar to transposition setting described in chapter 5.2.24, also you can 
have +/-1 semitone buttons (events 156 & 157), and +/-1 octave buttons (events 
158 & 159). But there are 2 main differences. Here, transposition is set at once for 
ALL keyboards in the system, regardless of what was played last, and this setting is 
applicable only as long as the power is on. After power cycle, transposition returns 
to initial settings, as adjusted by other means. This way of transposing is 
recommended for performance control, where you may want to frequently shift all 
keyboards. Go to chapter 5.1.2 for more details.

 5.2.27 

MIDI notes for stops control - #2160

In this mode keyboard plays normal MIDI notes, just like with standard note event 
131 (chapter 5.2.5), but there are 2 differences: Global Transposition does NOT 
affect this keyboard, and starting note number is 0, like other non-note events. This 
is useful in organ emulators, where stops can be controlled by note-on/off 
messages, but you really don't want the stops to change positions, every time 
Global Transposition is used.

 5.2.28 

Reversed notes action- #2161

If keyboard's contacts are normally closed, and open only when key is pressed, you 
may take advantage of this mode. If keyboard is assigned to reversed action, MIDI 
note-on is sent when contact opens, and note-off when contact closes. There is no 
need to short any unused inputs of keyboard scanner.
