your trying to create new samples, so u need to copy that sample to however many zones u want instead of zoning it.... get it.....
because i think what ur doin is lets say ur zoning 4 parts... so when you start-end the first zone, u go to do the next and u are wanting part of the end of the first zone to be included in your second zone....kind of overlap zone-ing.... kinda hard to explain i hope u get what im tryna say here son....thats why i say if ur zoning to 4 parts, then just make 3 more copies of that sample so u got 4 total now, and THEN set start end points on each sample the way u were tryin to do with just the one sample....
p.s. anytime u slice a sample into zones, the start point will always affect the end point of the previous zone and the end point will always affect the start point of the next zone...
get back if im not gettin this right.. . . . . .
peace love and nappiness
