changing kick decay and trigger over a period of time

hey,

as a newbie i'm trying to find the most efficient way to do the following:

1. alter the decay time on a kick drum from a bang (for example: first bang 'Decay Time 50ms', fourth bang 'Decay Time 150ms', option to go random as well)

2. alter the timing slightly of the same kick drum (for example: first bang 'Delay Time 25ms', fourth bang 'Delay Time 175ms')

am trying to avoid typical grid sequencing but much prefer the audio rate option

hope that makes kinda sense

P ;)
