Is it possible to increase the lengh of a sample?

Hello, new to sampling world here, im wondering if theres a way to increase the lengh of a sample since ive a set of m1 pianos and organs but if a want to play lets say a long piano chord am i limited to the lengh of the sample? ive set sample release at max but sounds the same also if i play higher notes the sample lengh decreases, just wondering i have no idea of sampling tricks :) btw im using ableton sampler



thanks!!
