Problem with gp when playing with ableton tracks

#1

Hi GP world,
I must be overlooking something here but I am going to be using ableton live for some playback of tracks at some gigs, but I must be missing something quite obvious to those who already do this.
Every time I switch a rackspace during playback it changes the pitch of the rackspace, I noticed that when ableton link is engaged this does not occur so when playing along with tracks does link have to be on or is there something else going on that can be rectified.
Sorry for the noob question but I am new to ableton its not my usual daw.

Probably running Ableton with a different sample rate than GP

thanks for the quick response I did check this and it appears to be the same so unsure as why but when link is enabled it seems to work?
