Download the free Tom Cosm M4L Device called “Locator Trigger”
and use the “OSC TouchOSC” Device (this can be downloaded from Ableton)
Press the Learn button in the OSC TouchOSC Device to catch the incoming OSC message and map it to the corresponding Go Button in the Tom Cosm Device.
Now you can locate the Ableton Locator by pressing one of the widgets.
Super Easy.
Have Fun
