The pattern editor in Studio One is very powerful and nice(like the different lenght) If you could set for single pattern lanes also different playback modes like:

-Ping Pong so that it plays backwards after playing forward one cycle and vice versa.

-or just backwards

-a randomized start point

-and random pattern note playback in which the note order of a pattern is randomized, it is a nice addition to the trigger probability

-also a faded pattern note speed up/speed down would be nice,
