Triggering samples in Ableton live using GP relayer via my midi controller

Im really new to Ableton but am trying to figure out how to trigger audio samples i have in Ableton in real time via GP5. Any help would be greatly appreciated.

You can probably use OSC:

With Audio Samples you mean clips in Ableton?

In Ableton Live you can MIDI learn each clip and then send the learned message to Ableton Live.
On Mac you can use the IAC driver for that.
On Windows there are similar solutions to use virtual MIDI
What version of Ableton Live are you using?
