It would be courteous of you to tell people it's not free.

I just discovered all the Ableton CV Tools, which use "routing_manager1.58.maxpat" suffer the same problem as Audio Routes which uses "BrowseRouting.maxpat".

Unfortunately the devices appear to crash Live when loading an .als file or a Live Clip that was saved with one of them in it. I tested Audio Sender and Audio Routing Example. This occurs even when saved in their default state i.e. no routing assigned.
Recalling a Rack containing the devices seems okay.
