Help syncing 808 to Logic Pro 9

[freemake]

Hello,

For several years I was able to use my TR808 with an old version of Logic Express just fine, but now (after several years of not making any music) I have a copy of Logic Pro 9 and I'm a bit stuck.

For some reason, whenever I stop a Logic 9 song and then start playing it again, even if I set the position pointer in Logic back to zero (or not), my 808 won't go back to the start of its pattern, which it used to do in Logic Express, i.e. the 808 pattern will continue from wherever it last stopped. This of course means that even though it is playing at the correct tempo, the pattern does not fall into step with other sequenced instruments.

I'm sure fixing this must be something very simple that I'm just can't see because of my frustration. Can you please help me?

Thanks.
