The Logic Off Topic list

i am using logic 5.5 on mac os x, and using it to tranmit signals to a 
synth i built in max msp, the synth interprets a list of two numbers, 
pitch, and duration, is there a way to make logic transmit the length 
of the note being played rather than just signifying the end of the 
note when the velocity hits 0? any suggestions would be much appreciated


thank you very much
