I have a small problem with syncing these two devices. all works perfect exept for one thing: 
when I stop my sequencer (logic8) and start it again the a-155 does not start from tick 1 but 
from tick 2, it resets itself to 1 but 9 times out of ten i sort of jumps over tick 1 and just 
starts from 2 so it is one step before the main sequencer (logic)... Otherwise its completly in 
sync only this weird thing happens...
