MIDI support for video functions

Assuming MIDI ranges equal 5 (the default):

Video Select

num     MIDI    Video
pad     Values  Clip
0       0..12   0
1       13..25  1
2       26..38  2
3       39..51  3
4       52..63  4
5       64..76  5
6       77..89  6
7       90..101 7
8       102..114        8
9       115..126        9
.       127     None

Note that a value of 127 disables video. If this is undesirable, set Video Select's MIDI range to 4.99 instead of 5.

Video Blending 

num     MIDI    
pad     Values  Blending        description     ROP code        GDI name
0       0..12   ~Src & Dst      AND inverted source with destination    DSna    
1       13..25  ~Src | Dst      OR inverted source with destination     DSno    MERGEPAINT
2       26..38  Src & ~Dst      AND source with inverted destination    SDna    SRCERASE
3       39..51  Src & ~Dst      OR source with inverted destination     SDno            
4       52..63  Src & Dst       AND source with destination     DSa     SRCAND
5       64..76  Src | Dst       OR source with destination      DSo     SRCPAINT
6       77..89  Src ^ Dst       XOR source with destination     DSx     SRCINVERT
7       90..101 ~(Src & Dst)    AND source with destination, invert result      DSan            
8       102..114        ~(Src | Dst)    OR source with destination, invert result       DSon    NOTSRCERASE
9       115..127        ~(Src ^ Dst)    XOR source with destination, invert result      DSxn            

Video Cycle Length

num     MIDI    Cycle
pad     Values  Length
1       0..12   1
2       13..25  2
3       26..38  3
4       39..51  4
5       52..63  5
6       64..76  6
7       77..89  7
8       90..101 8
9       102..114        9
0       115..127        10

Note that numpad zero sets the cycle length to "all" which is effectively 10.
