There's also compression in the Timefactor Ducked Delay algo.  I messed around with it last night and was impressed.  Combining it with a slapback setting on Delay B yielded a pretty good chicken pickin' tone.  I've never been able to keep a compressor on my board for long because I just don't use it that much live.  Having it available in the H9 for those few occasions that I do use it is a nice bonus.
