when i try to change the Pattern from Pattern 1 to Pattern 2, than it is not in Time. It sounds like, when i change the Pattern, it change not from the beginning of a pattern, always sounds like a change in the middle of a Pattern.
In the PROJECT > CONTROL > SEQUENCER menu, set CHAIN AFTER to PAT.LEN (see page 37 of the manual).
Make sure that this setting is not overridden by the settings of USE PAT SET and USE PRJ SET under CHAIN BEHAVIOR in the PATTERN SETTINGS menu (see pages 90 to 91 of the manual).
