iPad - drum sequencer - jumping around?

Hey guys,

when I open the drum sequencer it doesn't play a sequence. It jumps around weirdly. I've made a little video to demonstrate:

Am I doing something wrong?

Lemur 5
iPad 2
iOS 6.1.3 (I hope I don't have to move to 7 as I'm afraid it'll impact the performance of my iPad 2)

Best
Hans

EDIT: I have just checked on my iPhone 5S with iOS 7.1 - here it seems to work. Oh noooo.... I don't want to move the iPad to iOS 7....

Do you have Slave Clocks to MIDI set to off?

Please post a screenshot of your Lemur Settings page.

Best regards,
Nick

I have this when Lemur receives the clock over Wifi mainly. When i plug in the cable everything is fine.
