Hi, I am considering buying SR18 but have a question which i hope you guys can help with. I normally work in song mode and prepare and sequence all the patterns in advance. However what if i want to insert a few blank bars in the middle of the song, how can i do this? On my Boss BR i can insert blank patterns (or patterns with just a 'tick') which also help keep time whilst simultaneously playing an instrument. Does Alesis have something similar? I cant see anything in the reference list and the manual does not mention anything
