hey iam very happy that i found a program to translat midi to keyboard!!
but i cant get it to work every midi key stroke acts 2 times

pls make a defult option that every key stroke will only act one time!
every time a press on my midi keys it acts on impact and on relese:( icant solve it:( and cant work

i only need the four right keys on the midi to be right,up,down,left

some one can make me a preset that will press 1 time maybe?? thank you! very good program

ok i got it to work with the "eat" way but still its to hard this way pls make a defult choice
