I tried to create Aux Track by right clicking on the track view as normally I create Audio/Midi track. I didn't find option for that. Later I have found its in the Output Dropdown. Now ,
i. I have Vox track output to Aux1
ii. Then I have created a clone of Aux1 and renamed it to Aux2
iii. The Output of Vox track automatically changed to Aux2.
iv. I have checked the Output dropdown of Vox track : The Aux1 option is not there.
 
Next:
I. TrackA[Marimba] - I made output to new patchpoint - Patchpoint1 created
ii. TrackB[Guitar] - I made output to new patchpoint - Patchpoint2 created
iii. TrackC[Flute] - I made output to new patchpoint - Patchpoint3 created
I changed TrackB output to Patchpoint3
I changed TrackA output to Patchpoint3
I tried to change TrackC output to Patchpoint2, but neither Patchpoint1/2 available. Is that if there is no connection remains for any patchpoint they got automatically deleted?
 
Also I can see the Aux tracks in the Track/Console view. How can I see the patchpoints?
Can I create Aux track/Patch point first and then do the assignments?
 
Sorry for too many questions. Today I started learning on Aux Track & Patch Point.
 
~Help me~

All as expected. Cloning an audio track does not clone a patch point that is selected as input, just as cloning a synth track does not create a new instance of the synth that's assigned as input. And, Yes, patch points are automatically removed when all output and input assignments that reference them are removed. You can see what patch points are available by checking the I/O list of a track. I/O assignment may not be shown by default in the Console view, but can be added by checking it in the Modules dropdown.

I understand the concept of Patchpoint that if all the connections to a patch point are removed the patchpoint get erased.
But what about the question of the Aux Track? I am still confused.

I feel there should be option for create Aux Track & Create PatchPoint after right clicking an empty area of the Track View and we can create Aux Track or Patch point, rename them as per our convenience. Then we can route desired tracks / output to them.
Just my opinion [Not sure whether we can do this.]
