In Buzz, you're restricted to one step size at a time in the sequencer view. This is a drag if you're using multiple different time signatures in one track, because patterns in a different meter won't display properly if the the number of beats in that meter is anything other than a multiple of the original meter.
You can get round this by using LiveJump. When I use different time signatures within a tune what I tend to do is set the seq steps to the longest signature I'll be using and then use LiveJump on each bar of the shorter signature to make it look the same length in the sequencer display.
For example, if I've got a tune in 4/4 and 3/4, I'll have a LiveJump pattern on each 3/4 bar jumping forward (relative) one beat on the 4th beat of each 3/4 bar. That way the bars play as 3/4 but I can still view them with a step size of 16 or 32. It makes life a lot easier than if I had to view it all with a step size of 1.
Please see the attached file for an illustration; here, I'm using a couple of live jump patterns to 'skip' the 4th and 8th beats in 3/4 and 7/4 patterns respectively, whilst allowing the track to play normally for the 4/4 sections.
