The multipad will always start on beat one.
So my best guess is that your phrase isn't filling the bar(s) or that you recorded onto beat one.
For example, if your phrase ends on beat 2, there will be a 2 beat silence (beats 3 and 4) before the multipad starts the repeat on beat one.
If when you recorded your phrase you ended on the first note of the repeated phrase, the multipad won't start the repeat until it gets to beat one of the next bar.
Basically, you have to play until beat 4 (and no more!) to get a clean loop using the multipad.
Not sure what you mean by 'midday' pad, so this might not be the issue.
Hope that was clear enough.
