sorry i forgot all about this

I did get my sbx but have only had it turned on once.......

i was trying to use it as a master to control a 202 & 303 and it worked a treat, it was when i tried to slave the pc to it i had problems.

anyway i think you could stop machines ok when they were playing but i cant remember if you were able to start them again and they would go back in sync again.

i must have another look at it again and get back to you
