You could switch the decay/gate mode on the Redrum's kick channel to 1 (square icon), which means it'll play the sample for the length of the midi note. (If you've used Redrum's own step sequencer, copy the pattern to a track and disable Redrum's pattern section.) Now you can adjust the kick length to your liking.
