How to adjust quantity of bars and notes position?

hi there, got a question: I start record my play, it is automatically adding more bars while I play, in the end I got 8 bars but the actual play just did take 6 bars, so two bars in the end is just silence. How do I get rid of these unneeded two bars? I didn’t find it how to do it.
And one more question: if after I have recorded the play I notice some particular notes are a bit slow or hurry is there any way to adjust it? I didn’t find it either.

 

From memory you can adjust the "pattern length" back to the number of bars you require? Will check later and confirm.

To adjust the beat position, tap the pad of the sound you want to adjust then go into STEP mode. You'll see your notes notes there, lit up, in the grid. Play and and adjust to the position you need it to trigger in (you'll need to adjust them for each bar).

 

Appreciate you guiding
