I have some questions regarding the MBSEQ_HW.V4 and LEDs set up: 
 
MBSEQ_HW.V4 says: 
#           SR  Pin 
LED_TRACK1   1   0 
LED_TRACK2   1   1 
LED_TRACK3   1   2 
LED_TRACK4   1   3 
 
#                SR  Pin 
LED_PAR_LAYER_A   1   4 
LED_PAR_LAYER_B   1   5 
LED_PAR_LAYER_C   1   6 
 
#         SR  Pin 
LED_BEAT   1   7 
 
 
But on http://www.ucapps.de/midibox_seq/mbseq_v4_dout.pdf the order is opposite. I guess this is not a misstake, but why is it different? 
 
Next questions, further down: 
#           SR  Pin 
LED_GROUP1  11   0 
LED_GROUP2  11   2 
LED_GROUP3  11   4 
LED_GROUP4  11   6 
 
#                SR  Pin 
LED_TRG_LAYER_A   0   0 
LED_TRG_LAYER_B   0   1 
LED_TRG_LAYER_C   0   2 
 
Is SR 11 the first shift register on board 2? 
Why is LED_TRG_LAYER_X = 0? Is it up to me to put in the numbers I want here?
