update, good news

problem was i was using the pads,
pads dont know when you release them,

you must use buttons,
and put them in momentary mode
choose a sysex string of length 5, as this will give you the 7 bytes as in ketron sysex pdf
and then choose the sysex string with data type SINGLE which gives you a VARIABLE byte
you then choose the 5th byte as variable
this 5th byte is the Status byte (pressed, released)
you can set it 7F(pressed) OR 00(released), doesn't matter

and the trick is then to set your low value to 127, and high val to 0

and YES you button will press, and release via one button press

and i also have the volumes working too, via CC volume message (7)

i know this all sounds complicated,
i was determined to figure this out, and i did

feel free to email me if you guys need help

time to buy my Novation SL MKII 61 key, and start programming
