Dear All,
On a track I have created lot of nodes and line for automation[Volume]. Now I want to get rid of them and create a new afresh.
Even if I click on (-) sign and again click on to create new automation line all the previous nodes are appearing with automation lines.
Please guide me to delete.
Thanks & Regards
SG

Just right click the envelope and choose "Delete Envelope"
 
Or select the track, go to Edit > Delete Special and uncheck everything apart from Track Automation

Thank you. Right now I am in office, will go back home to try out.
