Resampling was thinking that. Dont see anything about envelopes in Zones Lampdog. The parameters in zones are there for a reason I suppose like switching between samples using velocity...Just finding my way thinking out loud.. wont pretend to know more than i do. But thats how it looks to me. like Zones arent really designed for in depth layering to get a kick drum for example which is fair enough.
Anyway less thinking more doing...
THanks for the help with this. think using keygroups the way kronitron said is the answer I was looking for and then after that maybe resample it but ill have to delve in further.
