I recorded some user patterns. The Intro, Pattern 00, has an A Sub Pattern. I want to have a longer B Sub Pattern. Pattern 00 has a Pattern Length of 5 Bars in 4/4 time. When I try to save B after changing the Pattern Length in Record Setup, the Pattern Length forces the A Sub Pattern of Pattern 00 to also change. They appear to NOT be independent, even though the manual states that the Pattern Length in Record Setup is independent across Sub Patterns of the same Pattern. Am I missing something?
