need help with timing problem

ok, first off let me thank this community for existing, for without i would be up the creek without a paddle :)

to the problem, im putting together a project which will house sample banks of multiple samples, these are to be triggered by user interaction with kinect via max.

for the purposes of the sample banks, ive put together a patch housing the samples in polybuffer~, with play~ used for individual playback. what id like to know, is there a way to sync the play~ objects to the main transport tempo, allowing for realistic tempo control/manipulation on the various samples. i already found a tutorial online which achieved synchronization between samples, taking the sample lengths and transposing the samples in sync. ive posted the patch below, is there a way to sync directly to the tempo of global transport and in turn alter the samples or should i be looking more towards timestretching?

i have posted two examples, one using phasor and the other with groove syncing to wave

any help would be grateful, i know how basic this must be, but its puzzling me :)

thanks in advance and keep up the good work
